PCB_Dlg-ChangeCommentComment_AD

The Comment dialog.

Summary

This dialog allows you to specify the properties of a component's Comment string, independently of the component itself.

Access

Provided the target component comment string is visible in the workspace, the Comment dialog can be accessed in one of the following ways:

• Double-clicking on the comment string.
• Placing the cursor over the comment string, right-clicking and choosing Properties from the context menu.
• Using the Edit » Change command and clicking once over the comment object.

Options/Controls

• Width - the current text stroke width (the "thickness" of the lines used to produce the lettering).
• Height - the current height of the text characters. The character width used to display or print the text is automatically proportioned to this height. A minimum height of 36mil (0.9mm) will allow the string to be legibly photoplotted.
• Rotation - the angle of alignment of the comment string, measured anti-clockwise in degrees from the horizontal.
• Location X/Y - the current X (horizontal) and Y (vertical) coordinates for the bottom-left handle of the comment string (the point by which it is held by the cursor when moving). Edit these values to change the position of the comment string in the horizontal and/or vertical planes respectively.

Properties

• Text - use this field to directly enter the required text for the comment.
• Hide - enable this option to have the comment string hidden from the workspace.

• Layer - the layer the comment string is currently assigned to. Comment strings can be assigned to any available layer, click on the list to view and select a different layer, from all those currently defined for the board.
• Mirror - enable this option to flip the comment string across an axis that depends on the string's current Rotation and Location X/Y.
• Autoposition - the current positional style for the comment text, in relation to its parent component. Choose a style other than Manual to have the text remain in that chosen position as the component is moved and rotated. To freely position the comment text and have it follow the parent component's movement/orientation, choose the Manual style. The following positional styles are available:
  • Manual
  • Left-Above
  • Left-Center
  • Left-Below
  • Center-Above
  • Center
  • Center-Below
  • Right-Above
  • Right-Center
  • Right-Below
• Font - use this field to choose the type of font used for the comment's text, either Stroke or TrueType. The dialog will present options based on the chosen type.

Select Stroke Font

This area of the dialog and its asscociated option are presented only when the Stroke option is chosen for the comment text's Font.

• Font Name - use this field to choose the required Stroke font. Available options are Default, Serif, and Sans Serif. The Default style is a simple vector font which supports pen plotting and vector photoplotting. The Sans Serif and Serif fonts are more complex and will slow down vector output generation, such as Gerber.

Select TrueType Font

This area of the dialog and its asscociated options are presented only when the Truetype option is chosen for the comment text's Font.

• Font Name - use this field to choose the required TrueType font. The drop-down list is populated with TrueType and OpenType (a superset of TrueType) fonts found in the \Windows\Fonts folder. Note, the list will only include entries for detected (and uniquely named) root fonts. For example, Arial and Arial Black will be listed but Arial Bold, Arial Bold Italic, etc will not. Use the Bold and Italic options to add emphasis to the text.
• Bold - enable this option to make the comment text bold.
• Italic - enable this option to make the comment text italic.
• Inverted - enable this option to display the text as inverted, within a layer-colored bounding rectangle.
  • Inverted Border - use this field to specify the border around the text. The bigger the border, the larger the resulting bounding rectangle.

Tips

1. If the parent component has its Lock Strings property enabled, the comment text string cannot be selected or graphically edited. In addition, the Comment dialog will not be accessible.
