Closing a Revolved Form

Anonymous — Mon, 24 Jul 2017 22:33:35 GMT

Hi,

I'm having a really hard time with forms. Rudimentary forms are no trouble, however, when trying to revolve a form into existence and then close it, I'm getting some grief.

The basic shape is 2 circles tangent to each other, with an offset around the lower half of each to make a shell.

After the shell is made, I need to close the top. I get issues with coincident vertices at 3 locations. The middle location, where the point is, I have been able to resolve. However, the locations on opposite sides I cannot figure out.

It seems if I delete these points, weld them, or try to add a face instead of bridging them, they all result in the body losing its shape and becoming composed of planes and points, which I do not want.

I have struggled for probably 5 hours now to close this form without it exploding an I cannot.

Thanks for your time,

smellymane

Your problem may be due to not constraining the sketch properly. Check out this screencast. you can also get a slightly different result if you convert the solid body.

Hi,

Is this what you want to achieve?

Hi Timm,

Thanks for the reply. Pardon my ignorance, but is there anyway to do cuts with forms inside the form editor? I tried cutting the solid form outside of the form editor and going back into the form but this of course reverted the timeline and showed me the full solid. I need just a quarter of the fully revolved solid.

I also tried redoing the sketch, following the exact workflow you presented, and still had the same 3 locations with the coincident angles error. This is tricky.

Thanks again!

Hi Saeed,

No. What I want is just a quarter of a spherical shell that doesn't have the coincident vertex error. I need it as a form because I manipulate it into a certain shape that is very difficult to do with regular solids.

That's the shape I'm looking for.

Thanks,

Scott

Hi,

Making this shape can cause you errors in the sculpt environment, so you can only imagine what editing it will result

Could you attach a picture of the final result that you want to achieve so that we can help you choose the right workflow
