How to transfer trimmed surface from Dynamo to Rhino using Rhynamo/Mantis Shrimp?

I’m facing some problems in transforming geometry from Dynamo to Rhino. Faces trimmed in Dynamo are not trimmed both in the 3dm from Rhynamo and in GH from Mantis.
This is the geometry

Actually, the 3dm is slightly better but with a very weird behaviour: half of surfaces correct, viz not (see pic)

in GH

Any suggestion?

First and foremost: No minimal reproducible sample files = no answers.


Sorry, I thought it was sort of well-known issue.

I was able to reproduce the issue. I will look at possible solutions and post here if I can fix this. Thanks for reporting.

I’m facing the same issue currently. Has a solution been found by any chance? Thanks in advance! I love using Mantis Shrimp!
