Zooming in and out
When you want to change the size of your design in the view space you will need to zoom in or zoom out.
Zoom in
When you want to view your design a bit closer you'll need to zoom in. When you zoom in you will see more details, but you might not see everything at once.
Zoom out
When you want to view more of your design you'll need to zoom out. When you zoom out you will see less of your designs details, but you will see more design at one time.
Fit all in view
You can use the Fit all in view command to automatically zoom in or out to fit your whole model on the screen.
