Took some doing and I uploaded a video of the process to the Autodesk site.

Are the drawings on the net correct for the bolt carrier?
Is this really smaller than 1.25 inches square and 3.1 long?
The bolt carrier I am designing does not exist in real life, that is one reason it is taking so long to build one for this project. It is a combination of AR180 and Airsoft L85A2. I can not speak to the accuracy of the drawings on the net but they are a good starting point. Measuring an existing AR180 bolt would be how I plan to model that when I get around to it.
