Why are all the extrusions jagged/polygonal?


When I make a loft or a boolean difference, I find that the resulting shapes aren’t smooth but polygonal.

Why is this happening?


A few examples

did you change Options>Mesh setup?

Hi, thanks for replying

No I didn’t change anything, should I?

Yes, try with smooth & slower option and also with custom setup.

Hi Alan,

Keep in mind that when in Shaded display, what you see is a mesh approximation of your accurate surface. You can ontrol the coarseness/smoothness of the display mesh by picking Tool -> Options -> Mesh. Just keep in mind that a finer mesh will be larger, thus possibly showing down the display of large models. Check the help file for more information on display meshes.

Hope this helps.
