The problem of data conversion from Brep to Curve is solved.
As you said, the model display options were not working properly.
The reason is that the Japanese menu is “detailed”, “simple”, and “scheme”… I misunderstood the meaning of the word. Setting it to “scheme”. worked for me. Attach the model view of ARCHICAD and the screen of grassshoppar.
The simulation is now possible. But there are still problems.
Thermal zone surface offset is in error. Your archicad data didn’t show any errors. I imitated your various settings many times, but I couldn’t fix it.
do you know why? Please let me know if you understand.
