How to Leave a Smooth Surface after Cutting from an Odd Geometry
How to Leave a Smooth Surface after Cutting from an Odd Geometry
(OP)
Hi, everyone.
I'm editing a model of an aorta in SolidWorks, and I need to cut off the some extra parts I do not need... Specifically, there are arteries coming off of the aorta. I need to somehow cut them off the main branch, but have the surface I cut them from be smooth after the cut. I was wondering if anybody had some ideas as to how I could do this.
Check out this image to see what I'm talking about: https://www.healthbase.com/hb/images/cm/aorta.jpg.
There are arteries at the top, which in my model would need to be cut.
Any ideas or thoughts would be appreciated. Thanks,
Phebotalus

TheTick - Thanks, I'll try using that function.
Eltron - Yes, I have tried that. But since the model is composed of hundreds of surfaces all at odd angles to eachother, SolidWorks cannot calculate how to properly make the cut.
ctopher - The function seems to be disabled, I'm not sure why.
bsj0526 - Could you explain more what you are talking about? I'm not sure I'm quite following what you are thinking about.

I made a representative geometry by creating a boundary solid between 2 ellipses and a sweep of another ellipse and saved this out as an STL.
Imported the STL deleted the faces joining the main body to the other body and then did a body delete with the rest. Surface filled the hole and knitted into a solid.
On the other side I tried a different approach by doing an extruded cut then filled then did another extruded cut slightly smaller and did another fill. This was to contain the faceted surface to an annular ring (check out the curvature before and after).
I hope this helps and makes some sence.

Also, 3d studio max or blender.org (free) could be used to edit these files.

If there is a way to get the STL in point cloud form the resulting shape will be a lot smoother.
