This documentation page references Altium NEXUS/NEXUS Client (part of the deployed NEXUS solution), which has been discontinued. All your PCB design, data management and collaboration needs can now be delivered by Altium Designer and a connected Altium 365 Workspace. Check out the FAQs page for more information.

Summary

Returns all objects whose X1 and Y1 properties comply with the Query.

Syntax

OnGrid(X1 : Number,Y1 : Number) : Boolean/Boolean_String

Each instance of Distance_String is a numerical string that specifies a distance in the PCB (Library) file. To be returned, an object's X1 property has to be an integral multiple of the first distance specified, and its Y1 property has to be an integral multiple of the second distance specified.

X1 and Y1 specify coordinates in the PCB (Library) file. To be returned, an object's X1 property has to be an integral multiple of the first value specified, and its Y1 property has to be an integral multiple of the second value specified.

All coordinates are referenced to the absolute origin (and not to the user origin or component insertion point), and at present, all coordinates always use units of mils. (1 mil = 0.001 inch).

Example Usage

OnGrid(25,25)
OnGrid(25,25) = True
OnGrid(25,25) = 'True'
Returns all objects whose X1 property is an integral multiple of 25mil and whose Y1 property is an integral multiple of 25mil.

OnGrid(5,100)
OnGrid(5,100) = True
OnGrid(5,100) = 'True'
Returns all objects whose X1 property is an integral multiple of 5mil and whose Y1 property is an integral multiple of 100mil.
