where I can find mouse sensitivity in catia ?

CATIA has an option to change the Pick Window size in order to have the cursor look at a larger/smaller area. Tools + Options - General + Display + Performance

Which means that you can control mouse setting in your system rather than in catia

guys I mean just like in alias there is a mouse sensitivity option to control how much the cursor can move when using control points or feature modeling in icem shape

I found it it's in the tools dashboard there is a step size and that's what I've been looking for, The small step size is useful when you want to do small tweaking to the control points

Thank you very much for sharing your experience with the community.
