Can't move black points in 3D Sketch

Anonymous — Sat, 30 Sep 2017 01:55:29 GMT

I'm designing a facemask via a 3D sketch and then sweeping a profile along the path. Most points are needed to be coincident but for some reason I am unabe to move several coincident points, specifically the black ones. Neither the points nor the lines are fixed.

Hi @Anonymous,

You can move the black (fit) points in a 3D curve. You just cannot "drag" them by just left clicking on them. Drag only works on 2D sketch data (because the drag is not ambiguous in 2D). So, edit the sketch, and use the Move command to move them in 3D:

Thanks for the reply. What’s weird is that I have been doing that. I ensure that I edit the sketch, select move on the point to where it gives it its multiple DOF. But when I attempt to move the point, the point stats while the arrow icon/cube moves.

@jeff_strater-I'm getting the same behavior with his file. Some of the points move with the move command, but some don't

here's a screen cast. lots of weird stuff here

Yep! That is exactly what I'm referring to. The sketch was intially made all on the same plane and then moved out from the plane from there. I have no clue as to why the points behave like that in this situation.

But in addition to this, most of the sketch features are splines, and when moving them from 2D to 3D, they lose all kind of functionality with the tangency/curvature handles. The green handles show but do not allow for any editing. I don't know if this might lead to other evidence but it's something that has also been happening in parallel.

By moving from a 2 d to a 3D spline you get into a very buggy area of Fusion 360. Apply a smooth or tangent constraint between the spline and maybe a projected line element and you either cannot move the handle anymore, or while the constraint symbol is still shown you can pull on the handle violating the smooth constraint. It’s very frustrating!

Yes, there are some bad behaviors to this sketch, thanks for sharing the video, @laughingcreek. We'll look into these. It seems like points with active handles cannot be moved, and there is some failure with a coincident constraint as well.
