Using 3d face function to mesh

[ranjit]

Hello!!..

 

I am using FE-pipe software for FEA analysis and it requires using Autocad to plot and mesh geometries.One example requires splitting the space between two concentric arcs into quads using "3D face" function. I have attached the before splitting and after splitting autocad files with this thread( I have got these files with the FE-pipe software) . Can anyone explain how one does this in autocad? Watever I do I cant seem to properly(ie. get the "begin" file to look like the "end" file)

begin.dwg

 

(I know 3dface function is used to define quads, but I cant understand how one draws these quads along a curve. One of the requirements for the FE-pipe software to work is that the corners of the quads lie on the curve itself).

 

PLS HELP!!
