Issue:

The Quadrangulate Mesh block stops at 50% or fails when meshing lattice structures.

Applies to:

• nTopology
• Export Part
• CAD Body from Mesh

Cause:

The Quadrangulate Mesh block isn't meant for lattice conversion. With lattices being so complex, the Quad mesh will try to run but most likely get stuck or fail. The Quadrangulate Mesh block was designed to use with Topology Optimization workflows.

Solution:

It's best to look at other methods to export your parts, such as meshing or slicing. If you are trying to export your lattice as a CAD part, check out this article to read up on CAD export limitations.
