Site-defined Mask Layers not showing up in Add Layers menu?

Make sure that your materialpath (Setup - User Preferences - Paths - Config) is set to define where your site defined layers are configured. There should be a masklayersitefile.xml here that defines the layers.

Thank you for the response, I was not able to find it.

Its in the screenshot you sent - third from the bottom..........

Ok, got it. What do I do now? Im not sure where my site defined layers are configured.

So as I first said you need to generate a masklayersitefile,xml, put it in a directory then point the materialpath to look at that location. Heres a COS solution How to create masklayersitefile.xml file (cadence.com)

Thank you very much.

I tried to open the link, but it brings me here.

So you need the either the HOSTID that your software license is hosted on or Reference key (which is allocated by the Cadence Channel Partner if you bought through them). You need a valid maintenance contract to be able to access the Cadence support site.
