model mania is a modeling challenge - not a drawing creation challenge. the counterbore in your model is at the correct depth. doesn't matter what the drawing shows for model mania.
The Counterbore depth is dependent on the plane from which the Hole Feature is created.
In this case it would be an imaginary plane in the real world as there is no part face to measure from.
The 7mm dimension is the controlling dimension that can actually be measured in the real world.
I've should have mention that I am using the model mania challenges for practice.
Thanks guys, I assumed that was the case when I dimensioned the part. Again, I was practicing and making sure my part was correct. I've failed CSWP segment 1 due to a wrong dimension.
