Hello,

To zoom in and out, you can use the mouse wheel.
Alternatively if you work with a laptop, you can also use the multi-touch trackpad (e.g. 2 fingers slide up or down on a macbook).

To rotate the model use the left button of the mouse (or trackpad).
To pan the model use the right button of the mouse (or trackpad).

Hope it does solve your issue. If it doesn't, could you let me know you computer configuration/browser so that I can have a look at that?

Regards

i am on a acer chrome book. what button do i use to zoom in and the button to zoom out? i want to know how because i am building something big. i mean BIG.

It is very easy to zoom in or zoom out screen by using a wheel of a mouse or you can use the zoom options from bar icon. The https://www.superiorpapers.com/ is one of my favorite sources to learn new about the trackpad and I think you should follow these instructions.

Thanks for posting this question — here’s what works for me when I need to zoom out (or navigation gets tricky):

If you’re using a mouse, simply use the mouse-wheel to zoom in and out. If you’re on a laptop or trackpad, you can often use a two-finger scroll (or pinch gesture, depending on your setup) to adjust zoom. To rotate the model, hold the left-mouse button (or trackpad gesture), and to pan/move the view, use the right-mouse button (or laptop equivalent). That’s exactly how I work when building large models.

If that doesn’t solve the problem: double-check browser zoom settings, or try another browser — sometimes performance varies depending on hardware or browser compatibility.

Hope this helps — happy building!
