Add a 3 max dimension to my drawing

[Hubert_Los]

Hello,

I am looking for a program to add a 3 max dimension to my drawing. I know it exists in a forum somewhere, but I can't find it. Can anybody help?

This rule is taken from my blog. (www.hjalte.nl) There you will also find other rules that will auto-dimension holes and bend dimensions.
