Curve Length Constraint
General
- With the function, you can set a constraint for the length of the spline curve if the endpoints of the spline curve are fixed.
- You can edit the shape of the spline by modifying the curve length value.
-
Add a Curve length constraint to a spline in a plane sketch or in a 3D sketch.
Add curve length constraint
- Select the spline curve.
- Select the context-sensitive menu function Constraints > Curve length.
The added length constraint is displayed only in the feature tree of the part.
Note:
- In a 3D sketch, you can use this constraint in modeling hoses, for example. The Piping Design hose parts use this technique.
- You can edit the constraint using the functions in the feature tree of the part. Select the dimension constraint and the context-sensitive function Edit, or double-click the dimension constraint.
