Put the sprue on a line angle by default

here's a quick tip!
If you place the sprue on the facial of a large crown, generally a size 14 block is required. If you place the sprue for a crown at the interproximal, it generally takes a smaller size block to get the job done and the milling time is shorter as well. But you have to cut the sprue off the contact area and if you are sloppy, you can remove the contact.
By moving the sprue location to the facial line angle by default you get the best of both worlds!
