That second video (runtime 16:12) is killing me from the official tutorial. The differences between the version in the video and the latest available are too wide for a newbie like me. I figured out how to make the arc in the bracket using the Tangent arc instead of the circle arc like in the video.

But then I get to the triangle (around the 8 minute mark) and it all gets frustrating from there. If I follow the video to the "T" that triangle won't be in the middle of the extruded bracket. When you resize the extruded triangle, it also resizes the bracket. I'm like okay, I guess it's cause I merged them and that's how the new version rolls. So I undid that. Made a new triangle sketch, extruded it and tried to resize it prior to merging it. What happens is the bracket still resizes with the triangle. I don't understand. Again, I was born yesterday on all this. It's why I'm still following tutorials. But it's hard to learn something when the information is outdated.

So is there tutorials more up to date with the latest version? Or lessons that use a version closer to how ver 3 functions then what I've seen in the official videos?

Preferably video, it's a better learning medium for me then text.
