To upload a CAD file:
Click New Project.
Use the dialog box to upload a file. You can upload multiple CAD files using control + select.
(Optional) Adjust the Model Scaling factor. For example, a value of 1.0 will not change the scaling while a value of 2.0 will double the size of the mesh, and a value of 0.5 will halve its size.
These files can also be uploaded while still compressed as GZ, TAR GZ, and ZIP files.
Upon successful upload, you'll be taken to the Geometry tab where you can modify your geometry as needed. Surface and volume tags from the CAD file will appear within the Geometry panel. They will retain the same names as they had in the CAD file. Names can be changed by right clicking on the existing name.
Important:
CAD geometries should be clean and watertight in order to guarantee that we can import them. Review our CAD Model Best Practices.
CAD files created in non-commercially available versions of CAD applications (alpha, beta, or educational versions) may fail upon upload.
Note:
You can mix discrete/STL formats with continuous formats in the same project without any additional steps.
