Hello SOLIDWORKS Power-Users and welcome to the 16th SWPUC.


For 5,000 points and eternal glory proposed the best, most elegant technique for unknitting a surface body in its individual faces.




  1. Download the attached file
  2. Use these options for importing the file in SOLIDWORKS. We need a surface body as the result.


     3. Resolve any topological errors at face level. Gaps are acceptable.

     4. Using only SOLIDWORKS features (exporting out as a neutral format (or other type of format), and importing it back, with the option to not knit faces is not acceptable) "unknit" the existing surface body in such a way that would generate individual bodies.


You get an extra 1000 points if you explain in detail your method.

Other 1000 prizes and certificates of SOLIDWORKS Power-User can be won, if your method stands out.


In case you are a programmer, and would like to submit a macro for performing the unknitting, we should have a separate award. The user submitting the fastest macro that will get the job done, will get 5000 points. The only conditions are:

  1. You wrote the macro.
  2. You gift the macro to the SOLIDWORKS Community
  3. Ideally the macro should prompt the user to select a face belonging to a surface body, or multiple faces belonging to multiple surface bodies, and unknit the bodies in individual faces. If those faces are pre-selected, the macro will go ahead and unknit the surface bodies that contain the selected faces.
