Help needed: what's the best way to create surface from 3D paths in fusion 360?

[Anonymous]

I am trying to create an irregular shaped surface by spanning several paths (see below), and I couldn't find in any of the YouTube tutorials on how to do this in Fusion 360. 

The closest thing I could find was using the Patch tool, but the surface created is not correct, as it does not go through the slanted lines (bottom picture - surface interpolation introduces unintended curvature).  The work-around I have is to trim this into 4 separate sketches, and patch each separately, and then stitch them together.

It seems there should be a way to connect these paths to create a surface.  (This is pretty straightforward in other CAD programs I've used.)

Thanks in advance!

Can you export and attach your *.f3d file here?

Will a Loft with Guide Curves return the expected results?

Thanks for looking into this.

I tried to make loft work, but I couldn't get it to accept the line segment as the profile.

There must be something like this in fusion 360, no?  (this is from Rhinoceros manual user's guide)

Hi @Anonymous

Lofting in Patch mode should work, but you need to turn off Chain Selection. See screen cast below.
