3D viewer missing; cant see where it is on my screen

so far cant see anything on the top of the bar, just what it looked like in videos and screenshots.
I got the free version, so please let me know if thats the case.

just to let you know i havent been using upverter lately so please fgure it out if i need an update or something to fix this, because 3d view gives me more of a balanced view of my prototype.

Hi there!
Take a look down the left-hand toolbar.
The bottom icon is an orthographic cube with “3D” printed on it:
Click on that, and you’ll get a 3D preview of your design.

Upverter is entirely web-based and completely free. You don’t miss out on anything just because you haven’t set up a credit card, and there’s nothing to upgrade.
