[DesignModeler] Edge changed after importing CAD to DesignModeler

ntm5702 · August 2, 2018, 02:44

Hi all,

I'm very new to DesignModeler and I encountered a problem shown in the attached picture. I export the CAD file as *.sat file, then import this 2D geometry to DesignModeler. When I select edges, I found some circles are complete while some others are incomplete, only a small part of the circle. I'm pretty sure these circles are same in CAD and have no idea why this strange edge appears. If I process to mesh, these edges remain incomplete. Since I need to assign different boundary condition to different circles, I'm also worried that the boundary condition could be incomplete.

Anyone have encountered this problems before? Thanks in advance!

The picture is here, and the green region is edge.

Hi,
suggestions:
1. try to delete the edge in space claim
2. try use other cad file format
3. it is better to design this simple 2D model in space claim itself

Thanks...

Thanks for your reply! I will try to do it with Spaceclaim. Thank you.
