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), Alias draws a line between the endpoints and shows the distance.
   • If the curves are not tangent continuous, Alias draws lines showing the tangents of each curve and shows the angle between the tangents.
   • You can drag left or right to change the length of the tangent lines (if your curves are not tangent continuous).
   • If the Curvature option is on, and the curves are tangent continuous, Alias shows another locator pointing to the intersection, with the curvature deviation value.

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.
