adjusting hole size

Hello,
I was wondering if there are ΔΎ thing possible in MOI which I'm used from DS mechanical.
I used DSM previously and now trying to migrate to MOI.

1. Can I select the surface and draw onto it?
so far I noticed that I will always draw on zero height whatever view I have and not on the surface.
If I want to draw a circle somewhere on big plane on model I attached and subtract it from the surface.
Other words: make 0,5mm deep hole of 10mm diameter in the middle.
Is there a simple way of doing it?
All I can think of is quite complicated like create at 0 height and move manually for the value which would have to be calculated and then do a boolean diff.


2. Can I adjust hole sizes of the 4 holes in the corners?
Again, way I can come up with is quite complicated.

I would be very thankful if someone can explain to me.

Atached model is quite simple so it's easyier to see operation, but more complex models will be real pain doing above mentioned.

Thanks.
Juraj
