Hi Pilou,

> does it possible to insert a ratio of proportion on the 3axes?

I'm not quite sure what you mean - do you mean something that will deform the view by stretching it more in one direction than another direction?

It will not do that - it will perform an orthographic projection in the same way as the Top, Front, or Right views, but from any direction.

But you can control the precise view angle by using Options / View / 3D view angles - I think that may help if you want to get a particular angled proportions set up...
