Triangles and subdiv.

ZBrush Usage Questions
#1

I am having a problem reconstructing subdivisions as it pops the error “mesh contains triangles, operation cancelled.”
I have seen a lot of responses to this problem for in depth detail and all that but I am trying to do something much more basic.
I load a cylinder3D, go to edit mode, make polymesh3d, open geometry and hit reconstruct subdiv. That is when I get the error that the mesh has triangles.
I am trying to turn the cylinder into a octagon for a school project and can’t get it to work.
Does the default mesh come with triangles and if so what the heck for?

Any help would be amazing.

#2

that’s because there are triangles at the top.

Why not just adjust the number of sides in the initialize panel before you create a polymesh 3d?

#3

Yes, or:

  1. Select the PolyMesh3D Star in the Tool palette.
  2. Go to Tool>Initialize and press the QCylX button.

Ta-da!

Thank you so much. I am very, very new to the program. I didn’t realize that was a option.

Is there a way to do something like that to a object that is already a 3Dmesh?
In my class I am supposed to use the append in the subtool subpalett, to bring in the cylinder3D and resize that down to a octagon as well.

#5

If you append the Cylinder3D as a subtool it is automatically changed into a polymesh. It will then have the Initialize sub-palette that I describe in my answer above, and you can press the QCylX button just the same. (Experiment with the different options to see the results.)

Thank you again, very much.
