Custom Heatsink Integration and Board Cutouts

Hello,

I am designing a custom board for a fanless, high-temperature enclosure. I notice the RoboDesigner allows for custom board shapes, but I have a few questions about integration with thermal solutions:

1. Board Cutouts: Is it possible to define non-rectangular internal cutouts (e.g., for specific heat pipe routing or mounting standoffs) within the Layout Designer, or are custom shapes limited to the outer perimeter?

2. Heatsink: Is the standard heatsink attached to the CoM considered when generating the 3D CAD models (DXF/STEP)? What are the options for specifying a custom, taller heatsink (e.g., a skived fin or vapor chamber solution) that interfaces with the base module, and are there tools to model the mechanical constraints of such a custom component?

Sorry, no good answers for you.
Custom cuts are not yet supported. Will be supported somewhere in future, but not now.

And currently there is no support for heatsinks, either custom or off-the-shelf.
