Limitations of InterLayer Checks
Inter layer checks do not:
Permit checking between Etch Layers, such as TOP etch to BOTTOM etch
Same Layer checks (Coverlay_top to Coverlay_top)
Distinguish between a Trace (Cline) or copper area (Shape).
Other Classes, Subclasses, and objects that are not included in the Inter Layer checks are:
Drawing format
Analysis
DRC
Text (on any subclass)
Board geometry outline
Silk Screen layers
Named dielectric layers
The subclasses enabled for InterLayer checking are :
Conductor Layers (No Text) Place Bound (TOP/EMBEDDED/BOTTOM)
Pin/Via Layers Filmmask (TOP/BOTTOM)
All Mask Layers (stackup defined) Soldermask(TOP/BOTTOM)
Rigid Flex Subclasses Pastemask(TOP/EMBEDDED/BOTTOM)
Surface Finshes Subclasses User Defined Subclasses*
*User defined subclasses in excluded classes are not enabled.
