Hi,

I have been set the task of drawing a piston head in solidworks, and as I have very few hours under my belt I dont really know where to start.

It should ultimatly look something like this : http://www.autofieldguide.com/images/090505a.jpg

I need some help as to what sort of processes would be used to create this, I will happily put in the hours through the tutorials to learn how to use them but I first need to know what the tools I need are, mainly to cut out sections of a cylinder like can be seen at the bottom of the piston head pictured.

If time allows I also should put a dome on the top of the head, but again dont know what tool would be used to achieve this.

THanks guys/gals
