Zooming allows you to increase or decrease the size of the drawing viewport. There are five ways of zooming.
| 1) | Using the scroll wheel (mouse wheel) or the Zoom In/Zoom Out icons of the toolbar or the View menu Zoom In/Zoom Out options you may increase or decrease the viewport by 10%. |
| 2) | Using the zoom percentage dropdown you may increase or decrease the viewport by an arbitrary value. |
| 3) | Using the Zoom All icon of the toolbar you may readjust the viewport so that the bounding box is fully displayed and centered on the drawing area. See the “Setting the Bounding Box” section. |
| 4) | Using the Zoom Window icon of the toolbar or the View menu Zoom Window command you may define a selection box with the pointer. Drag the pointer using the left mouse button to draw a selection box around the region you want to zoom. When you release the mouse button, the drawing area will be redrawn so that the selected region occupies the whole drawing area. |
