🧾 What Zoom tools do
Zoom tools help you navigate around your roof model by changing magnification and position. Most zoom functions are available using your middle mouse button, including scroll wheel zoom in/out around cursor location, pan, and double-click to zoom fit.
When multiple views are displayed on screen, you must first select the view you want to alter. The current zoom scale is always reported in the status line at the bottom of the graphics area.
