I need to export a 3d model from Catia to be used in C3D. I have saved the Catia model as a .stp file. I then opened this file in Inventor and created a .sat file from it. I then imported the .sat file into C3D. The model appears in C3D as a mesh. When I check the properties of it, it is listed as a surface but it isn't a C3D surface or anything that I am able to use for quantities etc. Very confusing!!
I need to create a tin surface from this to be used for quantity checks. Can anyone offer any advice on this issue? I am not very familiar with Catia or Inventor but am very experienced with C3D.
I am using Autodesk Civil 3D 2011.
Thanks in advance!
Change the Visual Style from 2D Wireframe to Shaded or Realistic.
Thanks for the repsonses!
I got it to work by exploding the mesh twice which then left splines. Did a multiple PEDIT on these to convert them to 3D POLYLINES and then built my surface based on that.
