Grids and Cursors
Before placing objects in the Schematic Editor, set the grids to enable easier placement. Altium Designer offers three grid types: visible grids for navigation, snap grids for placement, and electrical grids for aiding the creation of connections. Grids are document options, meaning that they are saved with the individual design, and therefore, grid settings may differ between one design document and the next. Set the grids initially in the General region of the Document Options mode of the Properties panel.
Visible grids appear whenever the zoom level allows them to be sufficiently spaced, displayed as either lines or dots. The Snap Grid is the grid that the cursor is locked to when placing or moving schematic design objects. Electrical grids override snap grids since they allow connections to be made to off-grid parts. Enable Snap to Electrical Object Hotspots so that when moving an electrical object in the workspace, if it falls within the electrical grid range of another electrical object to which it could connect, it will snap to the fixed object and a hotspot (red cross) will appear. The electrical grid should be set slightly lower than the current snap grid or else it becomes difficult to position electrical objects one snap grid apart.
Grids can be quickly modified or toggled between enabled and disabled through keyboard or mouse shortcuts, for example, press G to cycle through the Snap grid settings of 10 mil, 50 mil, and 100 mil. You can also use the View » Grids sub-menu. Use the Schematic - Grids page of the Preferences dialog to set Imperial and Metric Grid Presets.
You can change the Cursor type to suit your needs in the Cursor region of the Schematic - Graphical Editing page of the Preferences dialog. For example, a large 90 degree cross that extends to the edges of the design window (Large Cursor 90 option) can be useful when placing and aligning design objects.
When the active document is a schematic document (
*.SchDoc) and no design object is selected in the design space, the Properties panel presents the Document Options.
The following collapsible sections contain information about the options and controls available under the panel's General tab:
The options in this section of the panel determine which schematic objects may be selected in the design space.
- All - On button – select to remove object filtering so that all types of objects may be selected.
- Object buttons – toggle each object button to enable/disable the ability to select that object type.
The following collapsible section contains information about the options and controls available under the panel's Parameters tab:
When a design object is selected, the panel will present options specific to that object type. The following table lists the object types available for placement on a schematic sheet – click a link to access the properties page for that object.
