Hairscale in pointdeviation doesn't work

Hello, I want to change the hairscale in pointdeviation pop up window.,
it doesn’t work.
can this be solved?

I have the same problem in Rhino 7.14. There is also a problem with bad point: when I try to type “0.7” zero is ignored.

Hi Problem is still not solved, hope to get a reaction from the Rhino developers, at the moment I’m working in Rhino 6 again to get around this problem.

Dag Albert -
I am not seeing that here.

From your screenshot, it would appear that you haven’t started the analysis yet. That needs to be done before you can change any of the settings.

Hello Wim,

I can change the number for the hairscale, but the scale remains the same. I asked my colleague overhere and he experience the same.


Hi -
Please run the Rhino SystemInfo command and copy-paste the result here.

Hi Albert -

What happens when you rotate the view? I filed a bug for those hairs getting clipped depending on the view - RH-68110.

Hello- this is fixed in 7.18, which is not available yet.
