How to add 3D sketch to existing 2D sketch

[broncomech]

I was asked to do some modifications to an existing project, most were simple edit the existing dimensions or add a fillet but one modification is proving to be very difficult.

There are a group of features that are perpendicular to a plane that the part owner wants rotated/tilted 15 deg.

3D sketch sounds like it should work but Fusion refuses to allow selecting the required plane when attempting to edit the existing sketch.

 I have managed to create the desired feature in a new project but can not duplicate the steps in the existing project, (see attached file). Is there any way to add 3D sketch elements to an existing 2D sketch?

There are multiple issues with this design right from the start.

But if you Edit a sketch, you can turn on 3D Sketching.

Check back in a few minutes.

Edit: I got pulled away into other stuff, but your first sketch is not fully defined. I doubt 3D Sketching will get you where you want to go with this.

I edited the original sketch, turned on 3D sketch and could only sketch on the original plane.

Note the file posted was only a test not the file I am actually working on, that file is not mine to post.

You should get a 3D triad to manipulate sketch plane.
