Arrowhead bug

I don´t use this command too much (arrowhead on curve), but does it work on mac? I can´t make it work!

Using Version 6 (6.23.20035.13182, 2020-02-04)

yeh works ok here on Rhino6 Mac & WIP Mac

weird, WIP works fine here as well, R6 not.

Works for me too in latest version of Rhino 6!

Hello - what happens? Does the command start then do nothing when you click on a curve, or?


Hi @pascal Pascal,
basically, yes. Command starts, but after clicking the curve, the arrow does not appear. Or is there any setting in R6 controlling the scale …?


Hi @petumatr, are you still experiencing this issue? I have had this issue for about a month or two now.

Hi @pascal — I can subtly see a graphical dot almost microscopic that appears after running the command. That allows me to assume that the command has been run and it has effected the selected end of the line, but it is not representing itself properly.

I am using Rhino for Mac Version 6 (6.24.20079.23332, 2020-03-19)
