I have a torus or a doughnut shaped object. I want to cut it in half like bagel with cream cheese. After using the slice curve and using group split my torus is hollowed out. If I redynamesh or use close holes, it closes the closes the center of the bagel. What am I doing wrong? I just want to cut a bagel in half.
Sorry. It closes the holes and the center of the bagel.
I am using version 4r8. I forgot to say that.
When there are two holes like this, the computer can get confused with how the mesh should be closed. You can help it out by using the curve bridge tool, or by using Zmodeler to manually bridge a few polygons before using an automated solution like close holes.
Is there any way to do this on a high resolution model?
I tried the curve bridge tool and it works almost perfect. It shows the lines set up in the right place but it is leaving overhang in a couple of spots. Am I doing something wrong? Is there a video on this tool?
Is there clean up you have to do?
I figured it out. I just have to watch a few videos and spend a little time on clean up. I appreciate your help. Thank you.
Simple tip, maybe this helps:
- try closing holes as you did
- normally the new generated polygons should have own polygroups
>> turn on showing polygroups - select that polygroup you did not want and delete it
When I close the holes, it fills everything in as one polygroup.
Hi,
but often the polygroup is not connected.
If so, you could just ctrl-shift-click-select that one generated polygroup, and with “polygroup > auto group” (or whatever the name was) you would get different polygroups.
Another workaround would be to create a (thin) thickness of your mesh first before you slice it, the slice it and close holes and you would definetly get more than one polygroups (because of the small gap between the inner and outer shells.
you select only the shells you need and delete the rest (delete hidden).
very simple it would be in maya with “bridge”.
sometimes other software is useful.
Here are three options, entirely in zbrush, that take less than 10 seconds each.
