Sweep direction?

jens_restemeier — Sat, 19 Apr 2025 07:20:17 GMT

I want to make an extrusion on an angled surface perpendicular to the Z plane, not the angled surface. Apparently the only way to do that is with the Sweep feature and a path.

For some reason I can only get it into the surface, not out of the surface. Simplified example (my project is much more complicated, I can't simply reorient the main surface):

This circle is a sketch on the angled surface, set up with a sweep with a short line as path. I read some suggestions that the direction of the sweep depends on the order of points in the path, but the path oriented either way seems to result in the same sweep. Is the little arrow controlling the direction of the sweep? I have not found a way to change its direction, though. Setting a negative value for direction doesn't seem to be accepted.

Please attach your model so the Forum users can take a look and work with your data. Just guessing, which one of these is what you desire.

ExtrudeSweep

If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

I attached my file. I need the bottom one, with the extruded surface parallel to the base surface, but the extrusion itself in the direction of the Z axis.

Convention is to have the path associated within the profile being Swept, you have shown this is not mandatory.

Your path is well below the profile and has Fusion unable to extend past and above your Profile.

Might help....

Hi,

Do you want an elliptical profile?

Thanks, looks like that was the problem:

I originally had the path closer to the origin, which put it below the plane of the surface. Putting it onto the surface makes it work.
