I can imagine for some users that it's hard to visualize in their head which part of the object will be visible. How can I make this more user friendly for the users? Should I put icons next to the options?
The 3D environment is considered in 3 axes, which is not easy to visualize for a non-professional user
In more immersive environments and advanced interfaces (Cinema,Blender). it is good to use options specific to reality.
However, if we do not have such a possibility, it is worth using the icons you mentioned
you can also use the clickable icon, but this pattern may not be intuitive enough
I'm not sure it's correct- isometric left proposition
