Cant create a loft

[mann.frazer]

Hi, ive attached a project im just about finished with and i cant create a loft of this slot at the back which a retention pin slides into. i would really appreciate it if someone could help me understand why this isnt working.

Thanks

I've never seen a 3d-Sketch being used for a loft. That might be because I'm a beginner in CAD / Fusion 360 but the proper way I know is using simple sketches with rails. Important is, that lines do intersect each other. This is described in this post perfectly. 

If you prefer multimedia tutorials you might want to watch e.g. this video::

You can create this loft.  As @lichtzeichenanlage says, 3D sketches take an extra step.  Normally a solid loft from sketch data requires 2D profiles.  Some of your profiles are 3D.  So, using the Boundary Patch command to create these "3D profiles" is the way to go.

I'm not 100% sure what you want the result to be, but here is one way to loft from this data:

@jeff_strater you'd have to agree though that for a new user that trick is hard to discover 😉

I agree 100%.  I was thinking this morning about how we could automate that.  Shouldn't be that hard.

A quick follow-up to this thread, a detail which I had forgotten in the first response.  The restriction on 2D profiles is only for solid Loft (in the Model workspace).  You can use 3D geometry in a surface Loft (in the Patch workspace).  But, since you probably want a solid in the end anyway, you would have to create boundary patches for those faces anyway, so the work is not that much different, I guess.
