Hi Once I have built a torus / doughnut shape, is there an easy way to increase the accuracy of the underlying geometry? i.e. When I go: View ==> Hidden geometry, I want to increase the number of segments in the circle. The reason why I want to do this is because I am going to want to use the sha…

definitely, it bypasses most of the inherent tolerances built into SU…

OK I feared as much. Thanks :smile:

[image] TheOnlyAaron: You will need to redraw using a circle with more sides Notice that the shape is the product of two circles: the profile and the path. Each contributes to the granularity of the final shape; to ensure a mesh that is uniform in both directions, change the number of segment…

Too true! Both “circles” should be redrawn to make the smoothest possible geometry. Also, @ship69 , you may want to try Artisan to smooth out the existing geometry, before startign from scratch.

Wait - except that I can’t make it work. Here’s what I did: click on the circle tool type in a number (e.g. “100” using the keyboard) click where I want the circle to start, and start dragging type in the number I want (e.e.g “25.5”) ==> but it drew in 24 sides Hang on, it worked for 48 sides. …

hit the Enter key after typing 100

Step 2 sets number of sides–hit Enterto execute, then set your center. -Gully

[image] john_drivenupthewall: stick to multiples of 4 drawn on axis, is best practice. Would 2 to the power of something be even better? e.g. 128. Either way would 128 be a reasonable number for a smallish slightly complex 3D shape that will have lots of curves? PS What is the convention he…

You want to have a point on axis at each cardinal point. Hence 4 on axis. -Gully
