Hi Michael,

As you noted earlier, it is the curved surfaces. Boxy shapes and 3D forms are more efficient.

The IGES file import is a full 3D model in VW and with boxy forms, triangles. VW 3D to 2D conversion offers fill (hidden line rendering) or no fill, aka wireframe. Wireframe = manual clean up while the other is fast and there is a manipulatable isometric with the bare minimum of lines as the product.

As you predicted, a sphere from MOI via IGES generates a complex 2D result using the hidden line rendering method vs. the wire frame (pics attached). So, yes, how the IGES curved surfaces are worked in VW is key.

I was hoping I had missed a MOI/IGES on-off switch, dial, slider, radio button or whatchamacallit that would help or that some bright spark would have a bypass. Alas, it is not to be.

Thanks,

Leonard
