Hi, i’m trying to find an easy way to apply some Holes in a circle.  
eg: the lug nuts for a wheel.

What is the best method to achieve this?

@lurka  
This is one way to achieve your objective.  
Draw a Circle representing the PCD

Draw a second Circle at point on the first Circle representing the Bolt diameter

Transform \> Move/Copy \> set this tool centred on the PCD Centre \> select the Bolt Circle [highlighted] \> select the Copy Icon [+] \> use the appropriate Arrow to Rotate e.g. for a 5 Bolt set up, 72º and repeat as required adding 72º each time.  
Divide 360º by the number of Bolts required, i.e., 4 will require a movement of 90º.
