Revolved Shell - Badly Shaped Elements

Nate6325 · September 8

I drew the cross-section of a flat-bottom tank in autocad and imported to Mecway as a dxf. If I revolve the full section, I receive an error stating that some elements are badly shaped. The elements that are shaped badly are those lying on the axis of revolution (lots of elements converging to a single point). I could include a hole at the axis of revolution to keep this convergence of elements from occuring but, I'd like to know if I'm missing a simpler solution that would allow me to model the entire top and bottom of a tank or vessel without this issue of badly shaped elements occuring. Any suggestions are greatly appreciated!

Including screenshot of revolved tank section with error message for clarity.

Normally, Mecway converts the on-axis elements to triangles and they're OK. One way this problem can happen is if the original node was slightly on the opposite side of the axis.
