From Rhino 6.27, which I am running on an Evaluation license, I am not being able to merge 3DMs, or bring them in as GDL, into AC 24. The Grasshopper-Archicad connection does work.
I get a
“The selected 3DM file could not be imported.
Unable to successfully process the file, try checking with the original author.”
With 5.5.4, for which I got a full license, Merge and import as GDL work fine. Is it that 6 Evaluation does not merge or import?
