Scaling breaks sketch

[anthonyrossi01]

I am trying to increase the size of a sketch scale using the "Sketch Scale" command. My issue is that the drawing breaks when I try to scale it. I would guess I am missing something about Constraints yet all of the tutorials I have watched don't really apply to lines that touch end to end. Warning: The rest of the file/timeline is a pretty good mess.

I think I did show scaling 2D geometry, including tangent arcs, in message 17, but here is the video form.  If it were me, and I needed to create different sizes of this geometry, I would use a set of user parameters and sketch dimensions to allow for different sizes just by changing those parameters.  Again, scale is destructive, because it deletes the dimensions.
