I'm a beginner with FreeCAD (0.19, Fedora). After some research and video tutorials I managed to design my part, expect one last step.
I created 2 lofts, to represent the outside and the inside of what I call the tunnel.
I now need to subtract the inside shape to the outside shape to create a big whole.
I tried to use the cut or the boolean buttons, sometimes after converting my lofts to solids, but this always ends up with something not expected.
I attached my project file. Here is a view of what I want after playing with the visibility but I can't achieve the same in an exported STL file.
How to subtract this loft to another?

Re: How to subtract this loft to another?
Lofts : Solid=true
Why do you need bodies and parts ?
Code: Select all
├ Cut (Cut)
│ ├ TunnelOutside (Loft)
│ │ ├ Face (Face)
│ │ └ Face001 (Face)
│ └ TunnelInside (Loft)
│ ├ Face002 (Face)
│ └ Face003 (Face)

Re: How to subtract this loft to another?
Many thanks Shalmeneser.
I know I shouldn't use multiple bodies but at my level that's the way I found to do more complex shapes.
Can you tell me what you did to my original file to get this result? (your first file)
I will take the time to have a deep look of your other files to understand how I should have done that.

Re: How to subtract this loft to another?
A loft in Part can be just a face or a solid.
Part create different solids and you need to fuse / cut / intersect them to get the resulting solid.
But 2 bodies and 1 part object do not give 1 object. You need to fuse them all. (Or select them all before export)
