I’m preparing an FE analysis model in Rhino, to import into Strand7.
I’ve found the most reliable CAD format for this seems to be IGS. There’s
one aspect of this that is causing problems though, it seems that the
export process removes split edges. I haven’t tried all the provided options,
can any one advise if it’s possible?
The resulting IGES surface has only four vertex.
I’ve been trying primarily the Lusas based settings (as this is a similar use case).
“Use Simple entities when possible” isn’t checked for curves or surfaces.
