Hi,
Anybody knows how to drive the length of a spline in TS7?
I have a spline with fix end points and I want to constrain the length of that spline to a given value.
When using the dimension tool in a sketch, it will let me put a length dimension but as a driven dimension and not a driving dimension

I don't have the most elegant solution to your problem but perhaps you can try using the 'optimize' command.
If you can parameterize your spline curve with a single variable x, e.g. angle of a control point
1. Create a 'Length parameter' L for the spline curve
2. Use 'Optimize Parameter' and fill in the following fields:
Measurement: L
Target: <desired length of spline>
Driver: x
3. Choose sensible min, max and tolerances etc.
