Even though you can use CET with a touchpad, navigating with a scroll wheel mouse is recommended. Below, we describe how the mouse buttons work.
Left mouse button (2D and 3D view)
Use the left mouse button to select objects, tools, menu options etc. Left-click and drag on an object to move it. You can also use the left mouse button for panning, but you could then move objects by accident. Instead, use the scroll wheel as described below.
Scroll wheel (2D and 3D view)
Roll the scroll wheel forward/backward to zoom in and out in the drawing.
Press the scroll wheel to pan (move side-to-side or up and down) the drawing without the risk of accidentally moving objects.
Right mouse button (3D view)
Hold down the right mouse button in the 3D view to circle or orbit around your focus point. Just clicking the right mouse button in 2D or 3, opens a context menu.
It is important to watch the color of the cursor as you work. It is subtle, but the color changes based on what you are doing and where the cursor is.
- White: the cursor is white when you are moving the mouse around to select toolbar buttons, menu options, or when it is idle on the screen.
- Blue: the cursor is blue when hovering over an object and when selecting an object. Objects will snap together when moving with the blue cursor.
- Yellow: the cursor is yellow when hovering over yellow rotation arrows or yellow snap/stretch points.
- Green: the cursor is green in the space between an object and the selection frame around it. When moving with a green cursor, objects do not snap.
