Hi,

Is there a way to merge two surfaces (using the union boolean operator for
example) and retain facet/triangle IDs for the merged geometry such that you
can differentiate between the original two surface mesh triangles in the
merged geometry? I am able to generate a merged geometry using the union
operation however, not sure how the surface IDs can be stored in the initial
surfaces and consequently be propagated to the merged geometry. Essentially
I want the output to be a single surface mesh with two distinct IDs assigned
to triangles belonging to shape 1 and 2 (used to generate the merged
geometry). Does anyone have a solution for this? Any help would be much
appreciated!

Best regards,

Nishant Ravikumar
