Broken display mesh - how to refresh? [Solved]

It seems that the display mesh of these NURBS surfaces is broken. How can I restore proper display and get rid of the mesh lines? (This is rendered view)

Hi Rolf - ShowrenderMesh/HideRenderMesh may be the trick here.

Much better, thanks!

But I’m also experienceing shortage of NURBS surface area… so to speak. After some filleting the flat vertical surface somehow “shrinked” although the nurbs structure seems intact. How to fix that? (compare with the wireframe below)

Hi Rolf - I’d extract that face (ExtractSrf ), delete it and then Cap the object (if it is solid) Does that fix it? Feel free to post a file with the object…

-Pascal

Done, sir.

Hi Rolf - there are a couple of locations that needed a bit of clean-up - that one surface was ‘bad’ (ExtractBadSrf) but you’ll see if you look where my red arrows are, where things were un-clean in your file.

OK, thanks. I didn’t really notice when that surface went bad, but based on your arrows it seems it was due to a FilletEdge command that the vertical surface went bananas.

Normally one would just undo until the wrecking is reverted, but I missed this one so I had no idea. Thanks.
