When using a custom getObject class to select surfaces I would like to be able to restrict the available choice to the faces of polysurfaces or extrusions that are on a predefined list.
It may be that I can’t see the wood for the trees but I can’t work out how to write a custom geometry filter to achieve that. Can anyone help?
Thanks for your reply. I’m ok with the general mechanism for custom geometry filters (e.g. I have one that restricts selections to closed solids) but the aspect I am struggling with is how to limit surfaces that can be picked to those that are components of objects in a list. Specifically, I guess, how to reference the object that a surface is a component of.
