Default Faces/ geometry.
Jack Keays
Posts: n/a

I have a face in a model which consists of maybe 20 edges and is highly curved. I want to replace one of the edges of the face with 2 different edges. However when I delete the old face and recreate it using the old edges plus the two new replacement edges, the shape of the curve/face is different. The original face was imported as an ACIS file. Has anyone any idea how I can over come this problem? Thank you. Jack.

Hi Jack

I pursume, you created the the geometry in Autocad/Solidworks/or Mechanical Desktop. If you are trying to create a curved surface, you should be using a spline, not a straight edges. 20 edges for a single face, results in a complex face to mesh.

My advice is draw the geometry (curved geometry), by a spline approxiamtion, this should be plenty good enough, until the number of edges curved or otherwise Regards is significantly reduced. Then export the sat file.

Regards Oliver

Thanks Oliver, but I htink my problem is simply that the original geometric parameters which describe the shape of a curved face are lost if u delete that face. IN other words, if you delete a face in Gambit, leaving the edges, and if you then create the face from the same edge, u end up with a different shaped curve when you render the surface. ANy ideas?
