Check continuity between curves

Check whether two curve endpoints have position, tangent, or curvature continuity.

Previous: Drag dynamic cross sections through surfaces

Show the continuity between two curves

1  Choose Evaluate > Continuity > Curve continuity.

2  Click the intersection of two curves.

• If the curves are not positional (the distance between the curve endpoints is greater than the Maximum Gap Distance tolerance), StudioTools draws a red line is drawn between the endpoints.
• If the curves are not tangent continuous, StudioTools draws lines showing the tangents of each curve and prints the angle between the tangents on the prompt line.
• You can drag left or right to change the length of the tangent lines (if your curves are not tangent continuous).
• If the Curvature Check option is on, StudioTools prints a message about the curvature continuity in the prompt line.

3  Click the prompt line history button (at the left end of the prompt line) to see the messages printed by the tool.

What if...?

I can't see the difference between the two tangent lines clearly?

Drag right, or choose Evaluate > Continuity > Curve continuity and use the options to increase the scale of the tangent lines.

I want to change the maximum gap distance tolerance?

Choose Preferences > Construction Options and set the Maximum Gap Distance option.
