The elephant in the room nobody talks about — Autodesk Fusion's generative design is actually more mature for multi-constraint topo-opt than SW right now, even in 2026. I know it's heresy on a SW thread but if your company has a Fusion subscription alongside SW, it's worth running topo studies in Fusion just for the cloud solve capability and the cleaner obstacle geometry workflow, then importing the output body into SW for the rest of the process. The export as a T-Spline body that you can then convert to a STEP for SW import is genuinely usable now. Worth knowing even if you live in SW land.
Combine this with a parameter sweep on load magnitudes and you can explore a design space automatically overnight. The API reference lives at help.solidworks.com API docs — make sure you're on the 2025 version of the docs, some method signatures changed from 2024.

Real talk — SolidWorks' native topology optimization (available through Simulation Premium) is honestly still limited for production use without a workflow wrapper. The results it gives are organic mesh blobs that you then have to remodel manually anyway. What I've actually shipped in 2026 uses a hybrid approach: run the topo-opt in SW for load-path intelligence, export the STL, bring it into nTopology or Altair Inspire for cleanup and lattice infill, then reimport the final B-rep solid back into SW for drawing and assembly. The AI part is in the middle step — nTopology has ML-assisted smoothing that respects your manufacturing constraints (minimum wall thickness, draft angles for injection molding, etc.). It's not magic but it cuts the "interpret the blob" step by about 60%. Check ntopology.com/resources for their 2025 workflow guides, they're genuinely good.
