Always learnt something useful from your video, thank you! A question here, I see the sketches for clean up the thread-end are not fully defined. Actually why we are always encouraged to fully define sketch? And when is it appropriate to not do so?
Nice catch, Because it is a tutorial, I did not bother myself defining it fully. Why are they important; In the real world applications, you never have the desired result in one go, which means you will revise your 3D's a lot. If your Sketches are not fully defined, they will fly around, and you will get a big mess after a small change. This is the principal reason, Secondly, it is easy to make changes on well-defined models Third, those dimensions are usable in drawings. You can directly get them to your drawing sheet. There are other reasons, but these are main ones.
You started very slowly which make easier to follow and understand the video, but as you progress, you were very fast. The same with with many of your videos I have watched. It would be great if you consider explaining a bit slower.
You're right, bro, I am already too fast, and when I prepared this video, I had only 30 min, so I rushed a bit more. I will keep in mind for the next tutorials.
