I’m trying to create a Perspective Projection drawing like this one in Rhino 5:
I know it sounds a bit weird (it’s an assessment issue in my country (NZ)).
I’m basically trying to reverse enginieer the drawing in image D above out of a building model.
So far it all works fine. The only part I’m having difficulty with is setting up (image B). I have to set the vanishing points parallel to the edges of the building.
I’m using the 2 Point Perspective view (thanks for that by the way!)
I’ve set up a station point (using the ‘place camera and target’ tool)
I’m now trying to set up the viewport properties (particularly the lens length), but I don’t know what lens length to use to get the 90 degree viewing angle.
Is there a better (quicker =) way of doing this?
Hope that makes sense.
Thanks for your help
