Hi Max, Thanks a lot. It works like a charm!
I'd like to know if it is possible to create NASTRAN bulk data file for geometries like the following [image: Untitled.png] I have the geometry in dwg and dxf file format created from AutoCAD. Basically, I have specified coordinate positions to create points at every delx= say,0.5 in CAD.
