Thank you for the link for the explanation, I was worried because the customer I am making this Bolo for was adamant about having the slight curve in.

Thank you for your help.

Hi Tom, yeah it's the same thing as in the link Marco posted above, just a display artifact and not any true problem.

The actual surface is fine there, and if you export to a mesh format you can force the export mesh to be refined in those areas by using the "Divide larger than" option in the mesh export dialog.

The realtime display mesh just did not get a lot of triangles in that particular area, that tends to happen with a shape that's fairly large but only shallowly curved. When the display mesher breaks things down by angle deviation, an angle of 10 degrees is kind of noticeable in an area shaped like that.

It's not anything actually wrong, it's just something to ignore. It's not really feasible for the display mesher to do a pixel perfect job like a full render because it's more oriented to do things fast.

Hi Brian,

> I noticed that doing Rebuild, to create more points, helps a lot, so does mesh angle of 1.

Best not to do either of those things though - it's just a display artifact and the best thing to do is to just ignore it.

Be careful setting your view mesh angle setting to 1 degree because that will make for an extremely high density mesh to be generated on other kinds of objects and you will easily run out of memory that way. So you'll probably want to put that setting back to the default 10 degrees which already makes pretty dense meshes on most things already, just not on things with this particular kind of "broad but very shallowly curved" specific type of shape.

The actual surface is fine and will respond to any modeling operation normally here, and you can make those problem areas to be more refined at mesh export time by putting in a distance in the "Divide larger than" meshing option at export time.

Michael, thank you for the excellent information.

Thank you for all your help.
