The lattice from CAD face doesn't match up with the CAD face shape

Issue:

The lattice from CAD face doesn't match up with the CAD face shape as I expected it to. 

Applies to:

  • Lattices, CAD faces

Cause:

This is because CAD faces are essentially 4-sided patches that are trimmed to a certain shape. When the CAD face is reparameterized, it uses the untrimmed surface, resulting in your lattice not matching the trimmed shape. This is a limitation with the CAD face format. 

Solution:

We are actively trying to improve this behavior. In the meantime, we recommend trying out different blocks to create a lattice from your part:
