The Schematic – General page of the Preferences dialog

Units

Select Mils or Millimeters, whichever is desired.

Options

• Break Wires At Autojunctions – enable this option to break wires at autojunctions (autojunctions are automatically inserted when two wires/buses/signal harnesses are connected in a T-type fashion or when a wire/bus/signal harness connects orthogonally to a pin or power port/bus power port).

• Optimize Wires & Buses – enable this option to prevent extra wires, poly-lines, and buses from overlapping on top of each other. Overlapping wires, poly-lines, or buses are removed automatically.

  You need to enable this option to have the ability to automatically cut a wire and terminate onto any two pins of this component when this component is dropped onto this wire.
• Components Cut Wires – enable this option to drop a component onto a schematic wire. The wire is then cut into two segments and the segments are terminated onto any two hot pins of the component automatically. You will need to enable the Optimize Wires & Buses option first.
• Enable In-Place Editing – if this option is enabled, the focused text field may be directly edited within the Schematic Editor rather than in a dialog box. After focusing on the field you want to modify, click it again or press the F2 shortcut key to open the field for editing. If this option is not enabled, you cannot edit the text directly and you have to edit it from the Properties panel. You can only graphically move this text field.
• Convert Cross-Junctions – enabling this option denotes that when the addition of a wire would create a four-way junction, it is instead converted into two adjacent three-way junctions. Disabling this option denotes that when a four way junction is created, the two wires crossing at the intersection are not joined electrically and if the Display Cross Overs option is enabled, a cross-over is shown on this intersection.
• Display Cross-Overs – when this option is enabled, the wiring cross-overs will be displayed with small bridges on the currently focused schematic sheet.
• Pin Direction – enable this option to display the direction of pins of components on a schematic document. The pin direction is indicated by the orientation of a triangle symbol.
• Sheet Entry Direction – enable this option to display the direction of sheet entries on a schematic document.
• Port Direction – when this option is enabled, the port is automatically drawn to suit the I/O type attribute. The direction that an Input or Output Port is drawn will depend on which side of the sheet the Port is currently placed (left or right), when the Unconnected Left to Right option is disabled. 
  • Unconnected Left To Right – when this option is enabled, unconnected ports are always displayed in a left-to-right direction (referred to as a right style).
• Drag Orthogonal – if this option is enabled, when you drag components, any wiring that is dragged with the component is kept orthogonal (i.e., corners at 90 degrees). If this option is disabled, wiring dragged with a component will be repositioned obliquely. Click the check box to toggle its status. 
  • Drag Step – select the desired size from the drop-down. Options include: Smallest, Small, Medium, and Large.

Include with Clipboard

• No ERC Markers – enable this option to include No ERC Markers in the clipboard/
• Parameter Sets – enable this option to include Parameter Sets in the clipboard.
• Notes – enable this option to include Notes in the clipboard.

Alpha Numeric Suffix

Each part in a multi-part schematic component is uniquely identified by an alphabetic or numeric suffix. Use this drop-down to choose how the suffix is presented:

• Alpha – choose this option to use an alphabetic suffix with no separator (e.g., R12A, R12B, R12C). The setting will be applied to all currently open sheets.
• Numeric, separated by a dot '.' – choose this option to use a numeric suffix with a dot separator (e.g., R12.1, R12.2, R12.3). The setting will be applied to all currently open sheets.
• Numeric, separated by a colon ':' – choose this option to use a numeric suffix with a colon separator (e.g., R12:1, R12:2, R12:3). The setting will be applied to all currently open sheets.

Pin Margin

• Name – normally, component pin names are displayed inside the body of the component adjacent to the corresponding pin. This option controls the placement of component pin names. It specifies the distance (in hundredths of an inch) from the component outline to the start of the pin name text.
• Number – normally, component pin numbers are displayed outside the body of the component directly above the corresponding pin line. This option controls the placement of the pin numbers. It specifies the distance (in hundredths of an inch) from the component outline to the start of the pin number text.

Auto-Increment During Placement

Objects that are identified numerically will have their value incremented during repeated placement, based on the Primary and Secondary settings. For example, if Primary has a value of 1 and you press Tab during Net label placement and set the Net Name value to D01, the first net label placed will be labeled D01, the second will be D02, then D03, D04, and so on. Note that the numerical value must be the entire value or a suffix (it cannot be a prefix). Enter a negative number to decrement the value during placement.

• Primary – any object that is identified numerically will have its numerical identifier incremented by this value, if the value is edited during placement. Examples include Parts, Net Labels, Ports, Off Sheet Connectors, Sheet Entries and component Pins. 
• Secondary – any object that includes a secondary numerical identifier will have that numerical identifier incremented by this value. The Name field of Component Pins is a Secondary numerical identifier. 

Port Cross References

• Sheet Style – choose one of the following sheet styles for the cross referencing of ports on a schematic sheet or schematic sheets within a project.
  • None – no sheet style is added in the cross reference string of all ports.
  • Name – names of the sheets that the ports are linked to are added in the cross reference strings.
  • Number – the sheet numbers of the sheets that the ports are linked to are added in the cross reference strings.
• Location Style – choose one of the following location styles for the cross referencing of ports on a schematic sheet or schematic sheets within a project.
  • None – no location style is added in the cross reference string of all ports.
  • Zone – the reference zone numbering (the sheet borders have the zones) is added in the cross reference strings of all ports that are associated to the parent objects such as the location of sheet symbols.
  • Location X,Y – the locations of the ports are published in brackets in the cross reference strings for all ports that are associated to the parent objects such as the location of sheet symbols.

Default Blank Sheet Template or Size

• Template – use the drop-down to set the default user template that will be used to create new schematic sheets. If No Default Template File is selected, a default blank schematic is created when you open a new schematic sheet. Use the Data Management – Templates page of the Preferences dialog to set the path to the templates directory.
• Sheet Size – use the drop-down to select the default blank sheet size that will be created every time you need to create a new schematic document. Sheet size can also be specified at the local document level using the Standard Page Options settings of the Properties panel in Document Options mode.
• Drawing Area – reflects the dimensions of the sheet size chosen in the Sheet Size field. This field is uneditable.

File Format Change Report

• Disable opening the report from older version – enable to NOT create a report when an older Altium Designer schematic file format document is opened. The report informs you that the document was created in an older version of the software and provides some information on features of the opened document that may be lost or have changed. This option is disabled by default.
• Disable opening the report from newer version – enable to NOT create a report when a newer schematic file format is loaded in Altium Designer. The report informs you that the document was created in a newer version of the software and provides some information on features of the opened document that may be lost or have changed. This option is disabled by default.

Graphical Editing

The Schematic – Graphical Editing page of the Preferences dialog provides numerous controls related to the editing of schematic-based documents directly in the design space.

The Schematic – Graphical Editing page of the Preferences dialog

Options

• Clipboard Reference – if this option is enabled, when you copy or cut a selection within the design space, you will be asked to select a reference point. This is useful when copying a section of circuitry that is to be pasted back into a schematic sheet. This reference point will be the point where the section of circuitry will be held when pasting. Note that the clipboard reference location is overridden by the nearest electrical hot-spot if the Object's Electrical Hot Spot option is enabled.
• Add Template to Clipboard – enable this option to also copy the current sheet template to the clipboard when you copy or cut from the current schematic sheet.
• Display Name of Special String – enable this option to display the names of the special string used by Text String objects as faint superscripts on the schematic sheet.
• Display Names of Special Strings that have No Value Defined – enable this option to display the names of special strings when they have no defined value. Disable this option to essentially hide these names, which can be of great benefit when several special strings with long names start to overlap.
• Center of Object – hold the object being moved or dragged by its reference point (for objects that have one, such as library components or ports), or its center (for objects that do not have a reference point such as a rectangle).
• Object's Electrical Hot Spot – hold the object being moved or dragged by the nearest electrical hot spot (for example the end of a pin). With this option enabled, the software moves the clipboard reference location of the object that is about to be pasted to its nearest electrical hot-spot.
• Auto Zoom – if this option is enabled, the schematic sheet is automatically zoomed when jumping to a component. Zoom level remains as it was if this option is disabled.
• Single '\' Negation – if this option is enabled, a net name can be negated by typing a backslash character before the first letter in the net name. This applies to ports, net labels, sheet entries, power ports, and harness entries.
• Confirm Selection Memory Clear – the selection memories can be used to store the selection state of a set of objects. To prevent inadvertent overwriting of a selection memory, enable this option.
• Mark Manual Parameters – parameters displayed with a dot denotes that auto-positioning has been turned off and that parameters are moved or rotated with its parent object (component, for example). To hide the dots, disable this option.
• Always Drag – if this option is enabled, every time you drag a component (or selection of components) on a schematic document, the electrical wiring stays connected. Press the Spacebar to rotate the component(s). Use Ctrl+Spacebar to toggle the wire start/end mode (corner modes).
• Shift Click To Select – enable this option if you want to use Shift+Click to select specific primitives in the design space. When this option is enabled, click the associated Primitives button to open the Must Hold Shift to Select dialog to access a list of primitives from which you can determine which are to use this Shift+Click method for selection.
• Click Clears Selection – enable this option if you want to deselect all design objects by clicking anywhere on the schematic design space. Regardless of the setting, you can deselect a selected design object by clicking on it.
• Place Sheet Entries automatically – enable this option if you want to have a sheet symbol generate a sheet entry with a matching net name automatically every time a new connection with a valid net name is wired to that sheet symbol. Otherwise, a connection with no net name wired to a sheet symbol will generate a sheet symbol with a system-generated net name.
• Protect Locked Objects – enable this option if locked objects are not to be moved and are to be ignored if they are part of a selection that is being moved. Disable this option and you will be prompted with a warning dialog if you attempt to move locked objects.

• Display Strings As Rotated – enable this option to display strings at their rotation angle (including upside down and left-reading). Disable this option to have strings always kept as right-reading, as they are rotated.

  Note that this option is not available if the operating system supports DBCS (e.g., if Japanese or Chinese locale is set for the host OS).
• Reset Parts Designators On Paste – enable this option to reset component designators when pasting onto a schematic sheet. When components are pasted, their designators will be reset to "?".
• Sheet Entries and Ports use Harness Color – enable this option if you want Ports and Sheet Entries to change color to match the color of the Signal Harness. If you specify a color for the Signal Harness, the Port or Sheet Entry will change to match. Disable this option if you prefer your Port and Sheet Entries to maintain their default color.
• Net Color Override – enable this option to view net highlighting. When this option is disabled, the Net Color Override dialog will appear if you attempt to highlight nets.

• Double Click Runs Interactive Properties – enable this option to either open the Properties panel when editing placed objects using double click, or disable it to open the modal dialog when editing placed objects using double click.

  Right-clicking on a placed object then choosing Properties from the context menu will result in the modal dialog opening if the Double Click Runs Interactive Properties option is disabled. The Properties panel will appear instead if this option is enabled.

• Show Pin Designators – enable to display the pin designators in the design space.

Auto Pan Options

• Enable Auto Pan – check to enable auto-panning.
• Style – auto-panning comes into effect when the cross-hair action cursor is active and you move the cursor to the edge of the view area. If auto-panning is on, the sheet will automatically pan in that direction. Set this field to control cursor movement during auto-panning. The options are Auto Pan Off, Auto Pan Fixed Jump (pans the sheet by a fixed step, which is set in the Step Size field – the cursor remains at the edge of the view area), and Auto Pan ReCenter (pans the sheet by a fixed step, which is set in the Step Size field – the cursor is re-centered in the view area after the pan).
• Speed – drag this bar to set the auto-panning speed. The further to the left, the slower or finer the auto-panning movement.
• Step Size – enter a value to set the size of each auto-panning step. The step size determines how fast the document pans when auto-panning is enabled. The smaller the value, the slower or finer the auto-panning movement.
• Shift Step Size – enter a value to set the size of each step when the Shift key is held during auto-panning. This determines how fast the document pans when auto-panning is enabled and the Shift key is pressed. The smaller the value, the slower or finer the auto-panning movement.

Color Options

• Selections – this field shows the current color used as the highlight color for selected items. When an object on a schematic sheet is selected, it will be highlighted using this color. Click the field to access the Choose Color dialog in which you can change the color as required.
• Special Strings with No Value – this field shows the current color used as the highlight color for special strings that have no assigned value. A special string that has no assigned value on a schematic sheet will be highlighted using this color. Click the field to access the Choose Color dialog, from where you can change the color as required.

Cursor

• Cursor Type – select an option from the dropdown list to set the style of the "crosshair" editing cursor. This cursor is displayed when you are performing any editing action in a schematic document. The following options are available: Large Cursor 90 (cursor takes the form of a horizontal and vertical line extending from the edge of the document area); Small Cursor 90 (cursor takes the form of a small cross made with a horizontal and vertical line); Small Cursor 45 (cursor takes the form of a small cross made with 45 degree lines); Tiny Cursor 45 (cursor takes the form of a tiny cross made with 45 degree lines).

Compiled Names Expansion

The project is automatically compiled after every edit action that you perform, or whenever you run the Project » Validate command. Once the project has been compiled, multiple document tabs appear at the bottom left of the schematic editor design space. The left-most (Editor) tab displays your original, logical schematic. To the right of this tab there will be a tab for each compiled (physical) schematic - one tab in a standard design, or multiple tabs in a multi-channel design (a tab for each channel). Learn more about dynamic compilation, and examining the connectivity in the compiled project.

The compiled schematic is displayed when you click on the Compiled tab. The amount of dimming applied is configured in the System - Navigation page of the Preferences dialog (hover the cursor over the image to display).

On a compiled tab only the components are available for editing, so all other design objects are dimmed (to indicate that they cannot be edited). The dimming level is configured in the System – Navigation page of the Preferences dialog.

The options below apply to how the objects are displayed on the compiled tabs:

Display the expanded compiled names of the following objects – enable the below listed desired objects:

• Designators – when a design project is compiled, all the logical sheets are expanded into physical sheets, and as a consequence, some nets are also expanded to reflect on the expanded physical sheets. Enable this option to allow component designators on physical sheets to acquire expanded net information when logical sheets are expanded into physical sheets. The drop-down menu controls how the expanded compiled names of designators are displayed after the project is compiled.
  • Display superscript if necessary – when the logical designator name and the compiled designator name differ, then the superscript is displayed.
  • Always display superscript – display superscript text for designators.
  • Never display superscript – never display superscript text for the designators.
• Net Labels – when a design project is compiled, all the logical sheets are expanded into physical sheets, and as a consequence, some nets are also expanded to reflect on the expanded physical sheets. Enable this option to allow net labels on physical sheets to acquire expanded net information when logical sheets are expanded into physical sheets. The drop-down menu controls how the expanded compiled names of net labels are displayed after the project is compiled.
  • Never display superscript – never display superscript text for the net labels.
