In the Drawing Settings dialog, which tab would you use to change the coordinate system for the drawing?

• A. The Units And Zone Tab
• B. The General Tab
• C. The View Tab
• D. The Display Tab

Answer: (A)

Changing the drawing’s coordinate system is handled where units and spatial reference information are managed. The tab that combines measurement units with the coordinate system (zone, datum, and projection) is the one you use to set or modify the drawing’s coordinate system. That tab typically offers the Coordinate System options so you can select the desired projection and zone, which directly governs how distances and positions are interpreted in the drawing. The other tabs deal with metadata (General), view definitions (View), or visual/display options (Display) and don’t control the spatial reference. So the correct place to change the coordinate system is the Units and Zone tab.
