Import and inspect a relief mesh in Fusion
An STL is a mesh, not a dimensionally constrained CAD solid or a toolpath. Import it correctly before deciding how to use it in design and manufacturing.
Use Insert Mesh
In Fusion’s Design workspace, use Mesh → Create → Insert Mesh. Select the STL and set Unit Type to Millimeter. Adjust the up direction, center or ground placement as needed, then confirm.
Compare bounds with the intended size
Compare imported dimensions with the measured bounds on the result page. A curved bounding box differs from the unfolded length. Inspect holes, thin walls and disconnected fragments. Large meshes may need reduction in downstream software.
What remains before manufacturing
Plan CAM around the actual stock, workholding and tools, and inspect the simulation. This site supplies geometry and depth images, not machine programs. Even shallow reliefs can contain inaccessible detail; the operator must assess the process before a test cut.
