How have automatically all dimensions?
I don't know which program you are using but in Catia it works like that.
First you should create the technical drawing of the part you want to design then you should select the view you want to put your dimensions -be sure that your view is in the red rectangle- then click on "Generate Dimensions", do your arrangements and that's it!

but don't trust that button so much since sometimes it gives you undesired dimensions or sometimes it doesn't give you what you want so that u have to erase or add by your hand.If you miss out some of them, then you will be mistaken :) good luck
