What can prevent solids from combining?

Andi H Mar 6, 2014 10:01 PM

I am trying to add to solid bodies together. getter "Geometric Condition"? what could cause this. Some of the surface are parallel to each other

Hello Andi,

Can you post the part?

Do you have linear contact between them?

Usually non-manifold conditions, e.g. tangent contact or opposite corners touching along edge or point. Sometimes it's a surface irregularity that the parasolid kernel no likey.

Here is the problem I was trying combine the spiral bottom with top portion. THe top par was solidified based on surface I got from the bottom part. So I had alot of tangent contact

I guess when I changed the contact it fixed it

  Andi,
  
  Tangent contacts are one of the "non-manifold conditions" that Roland mentioned. It's a limitation in SolidWorks that you just have to work around, either by leaving tiny spaces or tiny overlaps where the tangency should occur.
