00:00 Intro
00:23 Learn what an undercut in injection molding is. We'll demonstrate how an undercut makes it difficult for a part to be ejected from the mold.
00:50 We'll discuss the 4 main ways to avoid an undercut in injection molding.
01:01 Shutoffs explained. You'll learn how removing material under the undercut can help the part eject better from the mold.
01:26 Moving the parting line explained. This is the easiest way to avoid an undercut in injection molding.
01:42 Bumpoffs explained. Learn when and how to use a bumpoff for undercuts.
02:16 Sliding side-actions and cores explained. Learn to use side-actions when an undercut can't be avoided.
02:47 We'll remodel a part with a snap-fit feature and undercut in Fusion 360. You'll learn how to create a shutoff by making a cut out under the snap-fit feature. Finally, we'll add a draft angle to the design.

    You forgot to mention lifters, which is afaik the most common way to solve the undercut issue after shut-offs, since they are cheaper than side-action and more flexible in placement.. Furthermore minimum draft angle for a metal-to-metal surface in the mold is typically 3 degrees minimum. 1.5 degrees for that shut-off is very tight. Wouldn't it also be simpler to just extrude with a 3 degree draft from the undercut surface through the bottom of the part. That way you dont have to create a sketch, and you don't have to use the draft command, so fewer features on your timeline.

    This is great and interesting (as was the previous video). You do a good job and that's lovely! As a suggestion for this video and the previous one: adding a really simple simulation of the ejection will help a lot to understand how your solution actually helps. If you do compare side to side the initial model without shutoff and your result with a shutoff, I am convinced that anyone could understand that ;-) Anyway, you do a good job, thanks a lot. And now I am waiting for the third video ;-)

    so something im working on is basically a box, but it would require a straight up hole (or two) in the side...seems like my only options are side action & changing the parting line, and changing the parting line would just create more undercuts...
