Which allows you to display a visualization cube that easily displays the ISO view on the other side by clicking on one of the corners of the cube (the gray one at the top in front of it for example).
_ Orient your 3D as you want (personally I use the keyboard arrows, or even shift + arrows, it's more precise)
_ Press "space bar".
_ Click on new view (logo of a spotting scope with a star). You can save this view with a name (like "ISO_2") and find this orientation when you insert a 3D view in your drawing!
The created orientation can even be saved for use in all your other 3D models...
