in the attached file I can´t change the preview mesh settings. No matter if I set the to low, high or custom settings, the preview meshing always remains the same (very coarse).
disable meshing is unchecked and as i pointed out, i tried all the various settings (low, high, document and custom). looks like a bug to me, i am on rhino 8 sr2.
something weird seems to go on here.
if i unpreview the custom preview component and preview the components plugged to it instead, the following happens:
disabling meshing does not show wireframe but gives the coarse mesh shown in my first screenshot
enabling any meshing (even low quality) shows a smooth mesh
also opened the file in V6. different result, but still not as expected …
