Very sorry for so many questions!
I'd like to control the size of a spline (sketch) with two parameters - width and height, while retaining its basic shape, just as in the figure below.
What I want is to make both the width and the height of the spline adjustable separately. But it seems that, either with Uniform Scale or Non-uniform Scale contraints on the spline, only one of the two parameters can be adjusted.
It seems that Scale Curve does not help. And also I don't want to constrain point by point on the spline, since some splines may have >10 defining points.
Do I miss something? Or is it possible?
In your file, when p16 (height) is increased, only pole no.3 moves up, and but poles no.2/4 stay fixed. Then the "basic" shape of the spline is modified.
I hope that, when p16 (height) is changed,
In your "Spline control_mf_02.prt",
I just find that:
Thank you for suggestion of Scale Curve feature!
My original goal is to use other objects and contraints in a single sketch to control the shape of a spline. In my plan, working in a single sketch would make the whole design, especially in case of many splines involved, much much easier to handle. It's very dissappointing to find that Scale Curve for Sketch does not help.
Using Scale Curve feature would require building some expressions to correlate the spline, scale factor and contraining objects. It seems to be a little sophisticated. But it seems to be the only way to accomplish the job. I would try it.
