Summary

Returns all objects on the following layers: Top Paste, Bottom Paste, Top Solder, Bottom Solder, and Internal Plane layers (Internal Plane 1-16). These layers are all of an "Inverted" or "Reverse" nature, because the presence of any object on these layers results in a corresponding opening in a solder paste stencil, or in the solder mask film, or a corresponding absence of copper (in the cases of Paste Mask, Solder Mask, and Internal Plane layers respectively).

Syntax

OnMultiLayer : Boolean

Example Usage

Summary

Returns all objects on the 'outside' signal layers – Top Layer and Bottom Layer.

Syntax

OnOutside : Boolean

Example Usage

OnOutside
OnOutside = True
Returns all objects on the 'outside' signal layers – Top Layer and Bottom Layer.

Not OnOutside
OnOutside = False
Returns all objects except objects on the 'outside' signal layers – Top Layer and Bottom Layer.

Note

Note that objects placed on the Multi-Layer layer will not be returned by the OnOutside query keyword. Use the OnMultiLayer query keyword to target objects on the Multi-Layer layer or the ExistsOnLayer('Top Layer') Or ExistsOnLayer('Bottom Layer') query to target objects (including objects on the Multi-Layer layer) that have shapes on the Top Layer or Bottom Layer.

Summary

Returns all objects on the Top Paste and Bottom Paste layers, and all pads on the Top Layer and Bottom Layer – the pad objects on these layers are returned because they also render to the Top Paste and Bottom Paste layers respectively.
