Assemble first component into asm

Afternoon all,

After reading this essentials book I have been given, it says the first component is always set fixed by default.  I do not want that.  I want to put the part where I want in reference to the asm datum planes.  For example mate offset prt plane to asm plane.

I am starting to struggle it seems with this SW stuff coming from my Pro/E world.  And yes I know I know.  I need basic training but this will not happen for a couple of weeks and in the mean time I need to get things done also.  the essentials book helps and the online help does, but I am struggling to find what I want and need.

Thanks guys.

Sid
