These preconfigured grids, also known as Grid Presets, are defing in the Schematic - Grids page of the Preferences dialog. While the current grid values are saved with each document, you can also define a number different grids that you want to have available as you work. Imperial and Metric units are supported, but it is important to appreciate that all Altium-designed components are created on a 100mil Imperial snap grid, if you switch to a metric grid, then the pins of these components will not fall on a neat snap grid. Grids are configured for each schematic sheet.Īs well as defining the current grid's settings, you also select the Units in the Document Options dialog, in the Units tab. Grid settings are saved with the individual design file, so grid settings may differ between one design document and the next. Set the grid values in the Document Options dialog, click Project | Content | Document Options to open the dialog, or double click in the sheet border.
The Electrical grid overrides the Snap grid to pull the cursor to the nearest electrical hotspot (such as the end of a pin) when the cursor is within the range of the current Electrical grid. The default Snap grid is in mils, and all Altium components are designed with their pins on a 100mil grid. It is important to select a Snap grid that suits both your company requirements, and also the components used in your designs. The Snap grid is the grid that the cursor is locked to when placing or moving schematic design objects. Note that the cursor is not locked to this grid. The color of the visible grid, and the choice of lines or dots is made in the Schematic - Grids page of the Preferences dialog. The Visible grid appears whenever the zoom level allows it to be sufficiently spaced so it can be displayed, as either lines or dots. This is the grid you see on the schematic sheet.
The Schematic editor has three types of grids: Grid Grids and Cursorsīefore you start placing objects in the Schematic editor, you need to know how to configure and use the grids, and set the cursor style. Just getting started in the Schematic editor? read on to get some pointers on how to place and edit design objects. Editing Objects in the SCH Inspector Panel.
