Moving Crv Start Pts to Acute Angle

by kleerkoat

I have a reoccurring issue here where I have a lot of curves that I have to manually move the curve seam to the point on the curve where it is at the the sharpest angle.

 

Attached is my first attempt on a single triangle using galapagos to find a point along the curve, but I'm not sure if my methodology is correct, and if it will be adaptable to the selection of 30+ curves.  One issue with the galapagos is it never actually finds the point, it gets close to the area of the point though.

 

Any help would be appreciated.

 

Thank you,

ryan

    If you really want to use Galapagos, you should do something like that:

    (set the number of digits to 6 in the slider)

    The trick is just to test the angle between the point on curve, and the 2 points just before and after it.

    It will probably faster to use Discontinuity if you only have sharp angles though.

    (Just saw Danny's solution, even better).

      thank you for the replies, I'm going to go over them and see what's going on with them.

       

      I'll probably be back with some more questions. ;-)

       

      thanks again!

        ok, so I've got it worked out thanks to you guys and it's working wonderfully.

         

        But now there is the question of how do I change those curve's start points to the point that it's found?
