spline adjustment in 3d sketch

Anonymous — Fri, 01 May 2020 18:31:13 GMT

I cannot adjust my spline curves in a 3d sketch. The handles don't work in fit point and the control points don't control. Julia with AD said that the control points should work but the fit point doesn't. I tried the control point spline and the cotrol points are dead. Is ths for real? I can't control curves in a 3d sketch. I feel foolish for asking this.

you have to use the Move command to adjust geometry in 3D splines - fit points, control points, or tangent handles. Drag will not work in 3D. Can you share your design here?

I do not see an issue with either type of Spline in a 3D sketch. I can move the fit points, adjust the handles of a fit point spline easily. I can also move the control points of a control point spline. Take a look at the Screencast, if I am not understanding your issue. let me know.

I can't get either the handles or control points (not here now) to work. I also can't select items to mirror. I will try move

this article: How-to-share-a-Fusion-360-design will show you how to share a design with us.

Sketch Mirror also does not work on 3D sketch geometry. Anyway, I don't recommend sketch mirror - model half of the boat, and do the mirror in the solid or surface toolset.

the handles don't move, the control points (not there now) don't move. https://a360.co/3d8QHrk

I can move the spline control point in that design with eh move command.

However, I've done a lot of surfacing in Fusion 360 and I don't think I'd create the curves for a boat all in one 3D sketch as that is difficult to manage.

Looking at the curvature there are probably too many spline control pints in that curve already.

here is a screencast showing how to move 3D spline handles using the Move command:

That worked! Thanks for the help.
