I was watching a video on the NYC CNC YouTube channel that was posted by John Saunders. If you haven't had a chance to see any of the videos he posts, you should go check them out. He does a really nice job with the projects that he does. If you like what you see, make sure you subscribe to his channel.
John has a segment he calls the Wednesday Widget. There are two videos for this project. One for the CAD design using Fusion 360 and one for the CAM design also using Fusion 360. As I was watching the videos I saw a couple of things that could have been done to make modeling this part a little easier.
In this first video I will show you a couple of different ways to draw the profile of this part. You will see how to use the line tool to draw a line that is target and coincident to two circles without having to do any trimming. You will also see that you can use the line tool in Fusion to draw an arc. We will also use the symmetry constraint to center a feature on the part.
In the second video, we'll look at a couple of techniques for quickly placing a hole on a part. A word of warning for the method used. If the geometry of the part is edited, the hole location will not keep the original design intelligence. The hole will stay where it was originally located. If the geometry of the part changes, you will have to edit the location of the hole.
In the final video I'll show you how you can select only certain elements of a closed profile while creating a 2D contour. A note about the methods shown. Holding the alt button down will only work using Windows. While using OS X the only way I could select an individual line was to click the closed profile and then click the closed profile again to bring up the open contour mini toolbar.
