Connect two dissimilar meshes with a curved, closed mesh net
When connecting two shells with dissimilar cross sections, a smooth transition from one contour to the other is often desired. This method performs just this task.
Note: You can generate only one connection at a time.
- Arrange the parts into the desired position and merge them into a single part using
Modify >
Edit shells > 
Merge selected parts.
- Select the new part and choose
Home >
Repair part.
- Remove the triangles closing the surfaces that you want to join.
- Select the triangles that include the open contours that you want to join. To do so conveniently, you can right-click the hole edge and choose
Select all surrounding triangles from the context menu.
Note: It is not necessary to select the triangles only that actually touch the open contours, so you can be generous in your selection. However, you must not select the entire shells, either. - From the main menu, choose
Join Contours.
The six steps of connecting two dissimilar shell ends: Two separate shells, Repair entered, shell faces opened, triangles that include the holes selected, transition generated, change applied.
