thats a very nice surprise Pascal thanks a lot, i think thats a useful plugin/script and works speedy enough for a bunch of such curves. they still have some hick ups though:
• escaping the py script before i do anything or after using match i get an exception error but it works after i select the direction. the plugin does not mind early escapes.
• when i pick a curve which has a corrected tangent already the script burps up an exception, the plugin just quits and leaves me with the otherwise very fancy direction arrow
something important still:
it changes the curve pretty strong, see picture below. using a degree 2 curve with 3 points is logically out of the question, so i rebuild it to degree 3 the match command does that automatically. but either way using the match command or your plugin/script it lifts the middle point up. the green curve indicates how it “should” be, achieved here through scaling the ControlPolygon Points in 1D to the boarders while the dashed green line was created through blend which results in a better continuity. but probably i am asking too much now, i believe that would need some deeper digging.
@maxz thats how i learned many things here either, good motivation for sure, this time i was probably too dumb and/or too lazy
yup the very first py script which is now replaced had “set tangent direction base point”, “pick point” is a bit too abstract i think.
