Guitarde Dormers Carpenter's Art

French Guitarde
Wall dormer or Balcony, circular or elliptical in plan view

This drawing is of two intersecting cylinders. I think I can develop the orthographic projections that will develop the correct curve of the intersecting cylinders.  I need to study this a lot more.

I started off with these two intersecting cylinders and realized that the horizontal cylinder is not rotated correctly. 

The horizontal cylinder rotated correctly for the guitarde.

 I'm not sure, but you might be able to build a guitarde with a cylinder and sloping plane. However, most of the guitardes look like the intersection of cylinders or cones.

Comparison of the sloping plane and horizontal cylinders intersecting the vertical cylinder.

Orthographic development for the sloping plane for a circular plan. 

Here are links to pages on the internet with the guitarde images on this page.
