problem geometry

[woodbutcher]

I've ben working on a cabinet sketch and was very detailed in drawing making sure to input dimensions by the keyboard and when i finished and went back to explode and dimension almost every measurement was slightly off. Anyone ever experience this? I have used sketch up for a long time, but never to do a detailed cabiet to build from.
