I’m working on a pretty basic problem, I’m trying to model a square room with 4 arches and a circular domed ceiling. Attached is a really bad picture but it should give you a sense of what I’m trying to do.
My approach is to make 4 arcs along the 4 walls
Then I want to make an arc across the diagonals. I’ll then rotate that arc to create the ceiling and cut it with surfaces from my 4 archs.
I think this all makes sense except for the life of me I can’t get an arc to go from one corner to the next. I am using the perspective view to chose my center point and start of arch, but then the curve gets created along the X,Y axis not the Z. If I use my Front view, I can’t select the correct points at all.
Below I use the Perspective and I create an arc from the correct point A to point B, but it’s on the wrong axis.
Below I use the Front view and I can’t even select the correct point A.
So my question is, if using the perspective view, how do I tell rhino that I want a curve (or any action) to occur along the Z axis?
Many thanks & apologies for such a simple question.
