Awesome. I joined this site specifically to get this plug-in. It's been a bane in my rear end that Sketchup couldn't simply draw dashed (or construction lines) that didn't go into infinity. Couldn't make a clean diagram that way. (And I know SU is more for 3D than CAD- but it makes sense to model something and then CAD it out in the same app. I also know Layout can draw them, but that gets messy too).
I literally just used the plug-in, but something I noticed right off I want to ask about:
I see that drawing the Construction lines flags to SU they are indeed construction lines. When I "Delete Guides" they are deleted as well. I tried grouping them and locking, but they still get deleted if I use the command. Is there a way to makes these lines unique to SU so they won't get deleted when cleaning up my drawings with the Delete Guides command?
Thanks again. This will cut down on a lot of cursing 'round here!
