I am migrating from V21 to 2017 Tcad Deluxe and am finding the construction lines to be too short to be very useful. I am used to them being infinitly long. Is there a setting, or method of creating construction lines long enough to go completely across the drawing?

Go to "Options / Native Draw" and click on the "Advanced" button. Checkmark "Construction lines" and anything else. This should cure having short $Construction lines. You could also use "F5" to refresh the screen. It's a Redway problem.

Thanks John! I might not have found that one for a very long while.. Works like it should now..
