Spline Point Stuck to Axis

famadorian

If I draw a spline, then have its end or starting point attach to one of the axis, it gets stuck;)

I can't move it from there. 

Is there some trick to "release" it from the axis' hold?

The end of your spline has a "horizontal" or "vertical" constraint to the origin.  If you hover over the endpoint that is "stuck" the constraint will show up as a horizontal or vertical line (respectively) within a blue box.  You can then click on this constraint and delete it with the delete key:

You can also easily find this constraint by checking the "show constraints" box in the sketch dialog, then delete it the same way.

Indeed; thank you, but I don't understand why it automatically puts a restraint on it, without me asking it to do it. 

Anway, thanks.

@famadorian - most of the time it is useful, other times it is just plain annoying - holding down the SHIFT key while sketching will disable automatic constraints.

Using shift …I would have thought holding down the shift key when you do want to attacht the point, because then it is a willful act…
