Incomplete or glitched surfaces

I re-opened my file containing a couch and the cushions have changed appearance. It is the same on normal or rendered views. The curves on the surfaces look correct but the actual surface does not. Do I need to remake these objects?

Hi JMurie -

can you export & post one of these objects?
One thing to try is this test command (does not autocomplete, save before using this command)


Does that clean up the meshing?


The command is unknown when I entered it. Here are a couple of the cushions.
cushions.3dm (2.3 MB)

Hi jmurie- ExtractSrf and UntrimBorder the large flat faces then rejoin … looks better here.


Thank you
