How do you line up viewports?

[Dadgad]

Now that you mention that you are using SOLVIEW generated viewports you might want to try this. Click into the respective viewports and zoom extents. I believe that will take care of your alignment issue.

It turns out, according to my experience anyway:

 

Construction lines were able to cross viewports in Paper Space vertically and horizontally, so basically I offset the construction lines by using through option to the geometry.

 

By using that technique, I get semi-permanent a visual confirmation. An object tracking method is much more ephemeral. (for lack of a better word.)

 

Thanks for all your help.
