Blend Line Failure

Problem86.3dm (39.0 KB)

In the attached I have a pair of blue and green lines.

If I try to do BLEND between the blue and the green, the BLEND command stops as soon as I click the BLUE curve.

BLEND {Command Ends}
BLEND {Command Ends}

(I was doing a bunch of similar pairs and these did not work.)

Hi Jim - the blue curve has two points staked up at the end. (= massive curvature)
-Pascal

Thanks, I could not see that even with zooming in.

Use CurvatureGraph for the curve. The resulting curvature comb has a spike at the end.

PointsOn to turn on control points. Then use window select around what appears to be a single point. Two points will be selected. I use this method to check for multiple control points when curves are behaving strangely.
