Overview
Roof Wizard is designed for highly efficient operation using a three-button mouse.
Once you're familiar with the controls, you'll be able to move quickly through commands and geometry input with minimal clicking.
This article explains what each mouse button does and how to use advanced shortcuts for zooming, snapping, and navigating your model space.
Basic Mouse Functions
Mouse Button | Function |
Left click | Selects commands or digitises a point on the screen |
Right click | Cancels, finishes, or aborts the current command |
Middle click (scroll wheel) | Snaps to a point or line end, opens inline commands or help |
It is strongly encouraged to use a mouse with a scroll wheel.
Zooming and Panning
The middle mouse button also gives you powerful view control:
Scroll wheel — zooms in and out
Hold middle button and drag — pans the job view
Double-click middle button — performs a Zoom > Fit-Screen
Ctrl + drag middle button — spins the model around the current viewpoint
These controls allow you to easily reposition or scale your view without navigating menus.
Snapping to Geometry
Snapping makes it easier to select exact geometry points.
Middle click — snaps to the end of a line
Shift + middle click — snaps and aligns to another line at the selected location
The cursor will now “jump” to nearby endpoints to help you place your pick box more accurately.
Why Use the Mouse This Way?
Using mouse shortcuts makes modelling faster and smoother — especially for large or complex jobs.
Once you’re familiar with these controls, they can save you dozens of clicks per job, especially when digitising outlines or adjusting planes.
