CAM放置和编辑技术

Using Cut/Copy and Paste

The CAM editor supports standard cut/copy and paste techniques using the following commands:

• Edit » Cut (shortcut: Ctrl+X) – clear the selected object(s) from the current document and copy them to the CAMtastic Editor's clipboard.

  After launching the command, the cursor will change to a square and you will enter cut mode. You will be prompted to select objects to include in the cut. Simply position the cursor over an object you wish to include in the selection and click. Clicking away from an object allows you to drag a selection area, for including multiple objects in the selection. Selection is cumulative.

  Continue adding objects to the selection and then right-click to effect the cut and exit cut mode. The selected objects will be cleared from the workspace and copied to the CAMtastic Editor's clipboard.

  The command can be canceled at any stage before the right-click by pressing Esc.

• Edit » Copy (shortcut: Ctrl+C (or Ctrl+Insert)) – copy the selected object(s) from the current document to the CAMtastic Editor's clipboard.

  After launching the command, the cursor will change to a square and you will enter copy mode. You will be prompted to select objects to include in the copy. Simply position the cursor over an object you wish to include in the selection and click. Clicking away from an object allows you to drag a selection area, for including multiple objects in the selection. Selection is cumulative.

  Continue adding objects to the selection and then right-click to effect the copy and exit copy mode. The selected objects will be copied to the CAMtastic Editor's clipboard.

  The command can be canceled at any stage before the right-click by pressing Esc.

• Edit » Paste (shortcut: Ctrl+V (or Shift+Insert)) – paste the contents of the CAMtastic Editor's internal clipboard into a CAM document.

  First, ensure that the document you are pasting into is not the original document from which the clipboard contents were copied, or cut from.

  After launching the command, the contents of the clipboard will appear floating, ready for placement. Simply move the cursor until the object(s) are in the required position, and click to effect placement.

  The object(s) to be pasted will not be floating directly on the cursor. The reference point for the original copy, or cut, is taken as the origin point of the originating document. Therefore, the actual contents of the clipboard may appear at some distance from the cursor, and you will need to zoom out in order to see them.

Multiple Copy

To copy one or more selected objects and then paste multiple instances of the selection wherever required in the current document, choose the Edit » Copy on Field command from the main menus. 

After launching the command, the cursor will change to a square and you will enter copy mode. The procedure involves the following sequence of actions:

1. Select the objects to include in the copy. Simply position the cursor over an object you wish to include in the selection and click. Alternatively, clicking away from an object allows you to drag a selection area, for including multiple objects in the selection. Selection is cumulative.
2. Once all required objects are selected, right-click.
3. A bounding box will appear around the selection and you will be prompted to select a reference point. This is a coordinate relative to the selected object(s) and is used to accurately position the copies of the selection in the workspace. Position the cursor where you wish the reference point to be and click.
4. A copy of the bounding box will appear floating on the cursor - held by the reference point. Move the copy to the required location in the design space and click to place.
5. Continue placing further copies of the selection (rather like using a rubber stamp), or right-click, or press Esc, to exit.

Clear Selected Objects

To delete selected objects from the current document, choose the Edit » Clear command from the main menus (shortcut: Ctrl+Delete (or Ctrl+E)). After launching the command, the cursor will change to a square and you will enter deletion mode. The procedure involves the following sequence of actions:

1. Select the objects to include in the deletion. Simply position the cursor over an object you wish to include in the selection and click. Alternatively, clicking away from an object allows you to drag a selection area, for including multiple objects in the selection. Selection is cumulative.
2. Once all required objects are selected, right-click - the selected objects will be removed from the document.
3. Continue deleting further objects, or right-click, or press Esc, to exit.

Mirror Selected Objects

To mirror selected objects about a defined mirror line on the current document, choose the Edit » Mirror command from the main menus (shortcut: Ctrl+M). After launching the command, the cursor will change to a square and you will enter mirroring mode. The procedure involves the following sequence of actions:

1. Select objects to include in the mirror operation. Simply position the cursor over an existing object that you wish to include in the selection and click. Clicking away from an object allows you to drag a selection area, for including multiple objects in the selection. Selection is cumulative.
2. Once all required objects have been selected, right-click.
3. You will now be prompted to select the first point for the mirror line. Position the cursor at the required location and click.
4. You will then be prompted to select the second point for the mirror line. As you move the cursor, a guide line will appear. Movement is restricted to vertical or horizontal planes only. When you have sized the mirror line as required, click again. A dialog will appear asking whether you wish to delete old objects. Clicking Yes will place the mirrored copy of the selected objects and remove the original selection. Clicking No will place the mirrored copy and leave the original objects.
5. Continue to mirror further selected objects, or right-click, or press Esc, to exit mirroring mode.

Move Selected Objects

To move selected objects in the current document, choose the Edit » Move command from the main menus. After launching the command, the cursor will change to a square and you will enter movement mode. The procedure involves the following sequence of actions:

1. Click on the objects that are to be moved, making them selected. Clicking away from an object allows you to drag a selection area, for including multiple objects in the selection. Selection is cumulative.
2. When all required objects have been selected, right-click. A bounding box will appear around the selection and you will be prompted to select a reference point. This is a coordinate relative to the selected object(s) and is used to accurately position the selection in the workspace.
3. Position the cursor where you wish the reference point to be, and click.
4. The bounding box will appear floating on the cursor - held by the reference point. Move the box to the required location in the workspace and click to place. The selected objects will be moved to their new position, relative to this point.
5. Continue selecting further objects to move, or right-click, or press Esc, to exit movement mode.

Rotate Selected Objects

To rotate selected objects about a specified rotation 'base' point, in the current document, choose the Edit » Rotate command from the main menus (shortcut: Ctrl+R). After launching the command, the cursor will change to a square and you will enter rotation mode. The procedure involves the following sequence of actions:

1. Click on the objects that are to be rotated, making them selected. Clicking away from an object allows you to drag a selection area, for including multiple objects in the selection. Selection is cumulative.
2. When all required objects have been selected, right-click.
3. You will then be prompted to select a base point. This is the point about which rotation will occur. Move the cursor to the required location and click to define this base point.
4. The Enter Value dialog will now appear, from where you can enter a value for the rotation, in degrees. Enter a positive value for anti-clockwise rotation, or a negative value for clockwise rotation. After clicking OK, the selection will be rotated about the base point, and by the rotation angle specified.
5. Continue selecting further objects to rotate, or right-click, or press Esc, to exit rotation mode.

Object Selection Tools

When in editing mode (carrying out an editing operation), you can use a number of techniques to select objects to act upon.

Objects will only be selected if the Add selection mode is enabled (Edit » Selection » Add). Conversely, objects will only be deselected from an existing selection, if the Remove selection mode is enabled (Edit » Selection » Remove). When in respective mode, you are free to add further or remove objects to/from your current selection, simply by positioning the cursor over individual objects and clicking, or by dragging a selection box around a group of objects.

The objects that can be added will depend on the selection modes enabled - Flash/Point and/or Draws.

• To toggle the Flash/Point selection mode ON or OFF, use the Edit » Selection » Flash command from the main menus (shortcut: Ctrl+F). With this mode turned on, you can include flash/drill point objects in your selection.
• To toggle the Draws selection mode ON or OFF, the Edit » Selection » Trace command from the main menus (shortcut: Ctrl+T). With this mode turned on, you can include non-flashed objects in your selection.

Use the following command from the Edit » Selection menu for object selection:

• Edit » Selection » All – select all objects in the current document, on all enabled layers.
• Edit » Selection » Display – select all objects that are displayed within the bounds of the design space.
• Edit » Selection » Window – select design objects within a user-defined area. After launching the command, the cursor will change to a crosshair and you will be prompted to select the first corner of the selection area. Position the cursor and click to anchor this corner. You will then be prompted to select the second corner. Move the cursor to size the selection area and click to anchor this corner. All objects that fall completely within this defined area will become selected.
• Edit » Selection » Crossing Window (shortcut: Alt+C) – select design objects within a user-defined area. The objects do not have to be wholly inside the defined boundaries of the area. After launching the command, the cursor will change to a crosshair and you will be prompted to select the first corner of the selection area. Position the cursor and click to anchor this corner. You will then be prompted to select the second corner. Move the cursor to size the selection area and click to anchor this corner. All objects that fall completely, or partially inside this defined area, will become selected.
• Edit » Selection » Previous (shortcut: Alt+P) – reselect the objects that were part of the previous selection, if you have previously carried out an action that involved making a selection of objects. Using this command during a current selection, where one or more objects have already been selected, will add the objects in the previous selection to the total selection.
• Edit » Selection » Object (shortcut: Alt+O) – select objects in the design space, one at a time. After launching the command, the cursor will change to a small square and you will enter single object selection mode. Simply position the cursor over an object to be selected, and click. Continue adding further objects to the selection as required.

Using the Selection Filter dialog accessed by choosing the Edit » Selection » Filter command from the main menus, you can define a filter to select particular objects associated with particular Dcodes, and located on specified layers. 

The top half of the dialog is used to define Dcode(s) and Layer(s) to be used in the filter. You can specify individual Dcodes and layers, or ranges, separated by commas. For example, to apply the filter to layers 2, 6 and layers 9 through 15, you would enter:

2,6,9-15

You can also specify Dcodes and layers that you don't want to be included, using the exclamation mark as a prefix. Using the above example, if you did not really want to apply the filter to layers 11 and 12, you would enter:

2,6,9-15,!11-12

Leave a field blank if you want to apply the filter to all Dcodes or layers.

Use the bottom half of the dialog to determine the type of objects you wish the selection filter to be applied to - either flashes, traces (draws), or both.

After defining the filter as required, clicking OK will take you back into the main design workspace, where you will be prompted to select objects. Simply drag a selection box around the entire design. Only those objects that fall under the scope of the selection filter will become selected.

Place Array

To copy selected objects and place them in a defined array within the current document, choose the Edit » Objects » Array command from the main menus (shortcut: Ctrl+A). After launching the command, the cursor will change to a square and you will enter array placement mode. An array is placed by performing the following sequence of actions:

1. Click on the objects that are to be included in the array, making them selected. Clicking away from an object allows you to drag a selection area, for including multiple objects in the selection. Selection is cumulative.
2. When all required objects have been selected, right-click. The Edit Array dialog appears. The dialog allows you to define the number of rows and columns in the array and also to precisely define the spacing for the array, using one of two methods:
   • Distance - this method allows you to specify the spacing between rows and columns, in relation to the size of the image (i.e. the selection of objects). When you specify a value in a Distance field, you need to add the required spacing to the value in the Image Size field and enter this combined value as the distance. For example, if the image size is 0.5inches and you require a 200mil spacing, you would need to enter 0.7 in the corresponding Distance field.
   • Gap - this method allows you to specify the direct spacing between rows and columns and therefore not dependent on the image size. For example, if you require a 200mil spacing, you would need to enter 0.2 in the corresponding Gap field.
   Click the Show Preview button to expand the dialog to display the array preview window, where you can view how the array will look when placed. The preview will update as you make changes to the array settings.
3. After defining the array as required, click OK to effect its placement. The array starts with the original selected objects and is placed upwards and to the left.
4. Continue selecting further objects to include in further arrays, or right-click, or press Esc, to exit.

Break Trace

To break a straight trace into two segments, choose the Edit » Objects » Break command from the main menus. After launching the command, you will enter break mode and will be prompted to select the location for the break. Simply position the cursor over the point along a straight trace - in which you wish to create the break - and click. The trace will be segmented at this point.

Continue breaking traces into further segments, or right-click, or press Esc, to exit break mode.

Chamfer Trace Edges

To bevel two adjoining trace edges in the current document, choose the Edit » Objects » Chamfer command from the main menus. After launching the command, the Enter Value dialog will appear. Use the dialog to enter the X and Y distances from the intersection of the two lines, at which the new connecting line should be drawn. After clicking OK, the cursor will change to a square and you will be prompted to select the first line. Simply position the cursor over the line and click. You will then be prompted to select the second line. Move the cursor over the line and click again. The new connecting line will be inserted, providing the bevelled edge that connects the two original lines.

Continue to chamfer further adjacent lines, or right-click, or press Esc, to exit.

Extend Line

To extend one line in order to meet another, in the current document, choose the Edit » Objects » Extend command from the main menus. After launching the command, the cursor will change to a square and you will enter line extend mode. The procedure involves the following sequence of actions:

1. Select a target line. This is the line to which the chosen line will be extended to meet. Simply position the cursor over the required line and click.
2. Select the line that is to be extended. Again, position the cursor over the required line and click. If the line to be extended, when extrapolated, would intersect with the target line, it will be extended to connect with the target line at this intersection point. If no intersection would occur, a warning dialog appears, alerting you to this fact, and the line will not be extended.
3. Continue extending further lines, or right-click, or press Esc, to exit.

Fillet

To fillet the connecting edge of adjacent lines, choose the Edit » Objects » Fillet command from the main menus. After launching the command, the Enter Value dialog will appear. Enter a value for the fillet radius and click OK. The cursor will change to a square and you will be prompted to select the first line. Simply position the cursor over the required line and click. You will then be prompted to select the second line. Again, position the cursor over the required line and click. The connecting edge of the lines will be rounded according to the fillet radius specified.

Continue filleting other pairs of lines, or right-click, or press Esc, to exit.

Join Objects

To join together individual line, arc and polyline objects, choose the Edit » Objects » Join command from the main menus. After launching the command, the cursor will change to a small square and you will be prompted to select a single trace (draw) object. Simply position the cursor over a line, arc, or polyline that is part of the chain of segmented objects that you wish to join, and click. The entire chain will become highlighted, indicating that the previous individual line/arc/polyline objects have now been joined, and will be considered as a single object for editing purposes.

Continue joining together further individual trace segments, or right-click, or press Esc, to exit.

Modify Objects

To change the shape and/or layer for selected objects in the current document, choose the Edit » Objects » Modify/Change command from the main menus (shortcut: Ctrl+D). After launching the command, the cursor will change to a square and you will enter modification mode. The procedure involves the following sequence of actions:

1. Click on the objects that are to be modified, making them selected. Clicking away from an object allows you to drag a selection area, for including multiple objects in the selection. Selection is cumulative.
2. When all required objects have been selected, right-click. The Modify/Change dialog appears. Use the dialog to change the shape (aperture) used for the objects, and/or the layer that they are drawn on. Leave a field blank in order for no change to take place.
3. After setting the options for the change as required click OK - the selected objects will be updated according to the defined modifications.
4. Continue selecting further objects to modify, or right-click, or press Esc, to exit modification mode.

Add Offset to Objects

An offset is a 'shadow' of the selected line or arc, drawn at a specified distance from the original. To place offset lines/arcs on the current document, choose the Edit » Objects » Offset command from the main menus. After launching the command, the Enter Value dialog will appear. Use this dialog to specify a value for the offset distance. After clicking OK, the cursor will change to a square and you will be prompted to select a single line or arc object. Simply position the cursor over the required object and click. You will then be prompted to select the side to offset. Position the cursor to one side of the line or arc and click - the offset line/arc will be drawn at the specified offset distance from the original.

Continue selecting further lines/arcs to offset (using the same distance), or right-click, or press Esc, to exit.

Scale Selected Objects

To scale selected objects in the current document, based on a specified base point and scale factor, choose the Edit » Objects » Scale command from the main menus (shortcut: Ctrl+U). After launching the command, the cursor will change to a square and you will enter scaling mode. The procedure involves the following sequence of actions:

1. Click on the objects that are to be scaled, making them selected. Clicking away from an object allows you to drag a selection area, for including multiple objects in the selection. Selection is cumulative.
2. When all required objects have been selected, right-click.
3. You will then be prompted to select a base point. This is the point of origin for the scaling. Move the cursor to the required location and click to define this base point.
4. The Enter Value dialog will now appear, from where you can enter a value for the scale factor, in terms of a percentage. After clicking OK, a dialog will appear asking whether you wish to scale apertures. Make your decision as required - the selected objects will be scaled from the base point and in accordance with the scale factor.
5. Continue selecting further objects to scale, or right-click, or press Esc, to exit scaling mode.

Edit Text

To edit text objects in the current document, choose the Edit » Objects » Text command from the main menus. After launching the command, the cursor will change to a square and you will be prompted to select the text you wish to modify. Simply position the cursor over the text string and click. The Edit Text dialog appears.

Use this dialog to modify text attributes such as font type (either Standard or TrueType), appearance of the text, and the actual content of the text. After clicking OK, the text will be changed on the document, in accordance with the options you have defined.

Continue selecting and modifying further text objects, or right-click, or press Esc, to exit.

Add, Delete, or Move a Vertex

Use the following commands to add additional vertices or to remove or move an existing vertex to line and polyline objects, in the current document:

• Edit » Vertex » Add – after launching the command, the cursor will change to a square and you will be prompted to select the line, or polyline, that you wish to add a vertex to. Simply position the cursor over the line segment, or polyline edge, that you wish to add the vertex to, and click.

  You will now be prompted to select the location for the new vertex. Move the cursor - a guiding line will appear as you do so - to the required location and click to anchor the new vertex. The ends of the original line will remain anchored, but the two segments either side of the new vertex will be redrawn to join at the new vertex position.

  Continue adding vertices, or right-click, or press Esc, to exit.

  • A single line segment will become a polyline object after adding a vertex to it.
  • Any polyline objects that contain more than two vertices may have a vertex deleted, or removed.

• Edit » Vertex » Delete – after launching the command, you will be prompted to select the vertex you wish to delete. Simply position the cursor over the vertex you wish to remove, and click. The vertex will be removed and the polyline will be redrawn accordingly.

  Continue deleting further vertices, or right-click, or press Esc, to exit.

  • A line, by definition, must have at least two vertices (i.e. its end points) and therefore you cannot delete a vertex from a line that has only two vertices.
  • If you click on a segment of the polyline, the oldest-placed vertex for that segment will be the one deleted.

• Edit » Vertex » Move – after launching the command, you will be prompted to select a vertex to move. Simply position the cursor over the required vertex and click. You will now be prompted to select a new location for the vertex. Move the cursor - a guiding line will appear as you do so - to the required location and click. The polyline shape will be modified accordingly.

  Continue moving further vertices, or right-click, or press Esc, to exit.

  • If you click on a segment of the polyline, the nearest vertex along that segment will be selected for moving and, although the whole polyline appears selected, the vertex to be moved will have a guideline attached to it.
  • The vertices of arcs may not be moved.
