Help with adding dimensions


New member
Hi all,

I've just started using inventor six. This is my first attempt at using a CAD program, so I began with the tutorial.
Using the tutorial "creating a part", ive managed to draw my first componant. The problem is when I go to add a dimension, the drawn lines (and the background grid) get completely hidden as I drag the mouse pointer over them!
I've followed the tutorial exactly, but cant work out what im doing wrong. Hope someone can help me.
