Hello, New to the message board, but I am a student studing Mechanical Engineering.  I am struggling with MMC, LMC, Tolarance, Allowance. and using plus-minus, single limit, limit dimensions.  I am using 2012 AutoCad.  If anyone knows a place online that can better describe these, and help me with using them on drawings that would be wonderful.

Thanks

On the dimension toolbar select "Tolerance" which brings up the Geometric Tolerance dialog box. Is that what you're after ?

For the dimensions you will create different dim styles for each of those that you listed, you might need several of each.

 

Use Tolerance command for the actual Feature Control Frame.

 

For Datums create one in Mulitleaders, that is what I have done.

 

For understanding GD&T without specific questions it is too wide open to help you.
