Importing an STL Midplane

An STL Midplane mesh is not a standard format. However, if you need to import a Midplane mesh that is stored in STL format, follow these steps:

1. Import the STL.
   
   In the Import dialog, set the model type to Dual Domain, not Midplane, and then click OK.

2. Click (Mesh tab > Mesh panel > Generate Mesh) and create a mesh on your model.

   This process will remesh the STL surface into a Midplane mesh (but the type will still be set to Dual Domain).

3. When the Mesh complete! dialog appears, click OK.

4. In the Study Tasks pane, right-click Dual Domain Mesh to change the mesh type to Midplane.

5. Assign properties (such as part surface) to the newly-created mesh.
