I have drawn a fit point spline and can't edit the points or or the tangent handles. I don't know what I did to cause this problem as I have other files that I can edit splines in. The spline that I can not edit is in "Sketch 1" in "stand extension".
Also when editing the tangent handles for splines is there a way from stopping them from being changed symmetrically? Change the length of the each end of the tangent handle a different amount?

Solved! Go to Solution.

Seems like these 2 tangent constraints are causing the problem but I don't know why.

No. The only way in Fusion is to use 2 splines. I know some programs allow non symmetrical handles but if you import an SVG with non symmetrical handles it gets split into 2 splines.

Weird that the spline can only be adjusted by inputting distances rather than dragging points.
Also weird that the tangents that you identified as a possible problem are not part of the splines
Could not figure out the problem so just redrew as tangent arcs. Splines seem to be a bit finicky from time to time. This is not the first time I have had this problem.
Thank you both for having a look.

The problem was the two coincident constraints where the splines touched a previously drawn curve. The constraints would have been created when I trimmed the linework between the two splines. Removing the constraints allowed the splines to be edited by dragging the spline points.

@laughingcreek The problem is the same as reported in FUS-64376 by @jeff_strater a couple years ago, I guess that's a little bit immemorial 😁. When fit point splines are coincident with projected geometry like this, it creates this condition. The sketch team has the ticket open, I just added more notes and asked them to look at it again.
