Perspective view, lines stucked horizontally, they can't go vertically

e.g doing a circle and it’s stuck like that I can’t make it by 90 degrees

you can work around by rotating it later, but in many cases its not the best

The default CPlane for the Perspective view is World Top, so any new planar object like a circle drawn in that viewport will fall on a plane parallel to that.

To draw a circle in another plane in the Perspective viewport, you need to change the active CPlane. See the user guide or the training manuals for more info on CPlanes.

I’d recommend having a look at a few Getting started video tutorials.
They can be found on the Learn page.
The User’s Guide and Level 1 Training guide are comprehensive sets of tutorials.
