To increase efficiency, you can separate your drawing model from annotations using the Model and Layout tabs.
It takes time to display dimensions, title blocks, keynotes, and other annotations. If you draw these on a Layout tab, display-time and visual clutter are reduced when you work on your model (on the Model tab). progeCAD allows you to dimension model space entities on either the Model tab or a Layout tab -- you can make the choice depending on the method that works best for your needs.
