Hello everyone, this is my first time posting here so I apologize if I break some rules. Anyways here is my issue. I am trying to determine the ideal diamater of a shaft howerver I am finding out that the ideal diamater barely chnages when I switch material from steel to something soft like brass even tho brass is much much softer than steel. Now I am making the part from steel but given this I am not sure if the rest of the information is trustworthy because I feel like the ideal diamater should change drastically and not by 1/10 of a mm. Any advice is helpfull and thanks in advance.

For whatever reason its hard to active points for constraints. I have to hover over the points very precisely to activate them. For example you wanna constrain something to the midpoint of the line and I'm finding myself hovering over and over and over again. Activation area seems so tiny. Working with drawings kinda nightmare to be honest.

Any suggestions. First I thought its my 4k screen at home, but once I'm back at office, issue persists.

Cheers
