Don, I have tried several times to open your example and get a message that it failed to open, no filter matching that file. Not sure what this means, I saved it (your file), closed my drawing, thinking that it wouldn't open the same drawing twice, still can't open it. Could this be because you have V16 and I have V12? I always forget to post that bit of important info...
Henry, I accomplished placing the flanges by using the "n" command after creating a group, then editing the group to get rid of the temp line. I then mirror copied using your suggestion of the shaft as midpoint snaps for the "mirror line". I had to extend the shaft lines on the "mirrored" (right) side of the drawing to meet the flange, which I don't really understand, as I drew them as protruding 1/2" on both sides of the grinder bearings, but I assume the mirror copy feature places them correctly, so I extended the lines to meet the flange.
I also copied the flange again so I could put one back next to the flange detail as a side view. Then placed two construction lines tangent to the "front view" of the flange in order to locate the side view as a projection. Two issues with that:
1.) I selected snap mode "tangent to an arc or curve" expecting to place the cursor on the top "edge" of the circle (90 deg) and snap to it. Instead, I got a point marked by an "x" seemingly in the middle of nowhere on the drawing and THAT is where the tangent line snapped to. Deactivate snap modes and the "x" goes away. I ended up placing the line by eye using the cursor and it appears to have landed where I wanted it. I am certain there is some sort of snap I could use to do this "properly". Should I have used "quadrant snap"? Would that have let me snap the construction line to the "top" of the circle?
2.) When I moved the copied side view of the flange over next to the front view I placed it essentially the same way I placed the construction lines in the first place; that is, by eye. Again, it appears I got lucky, but there must be a correct way to accurately do this that uses "snap points" on the construction lines. Right??
