Hi Brian, it seems to work to export curves to Alibre using SAT format.

If I remember right there may be something that they don't like to load files that have some mixture of both curves and surface/solids within the same file.

So try making an SAT file that contains only curves in it and you may be able to get those over.

Hi Brian, also it looks like you already found this but just in case anyone else is reading this and wants to know how to import curves into Alibre, there is also a different "insert surface" import method that can also bring in curves as well, which Ralf explains here:

But a regular import of SAT format seems to work also.

SAT format for a Catenary worked for Import to Alibre!
Thankyou.
