I understand, but when I attempt to drag a point from a freehand roof shape to match a point on another freehand roof shape, it jumps around as if snapping to a grid even though the grid snap is off. I cannot place one point from a freehand roof shape directly over another.

The basic problem is creating a homogeneous roof with multiple freehand roof shapes. My assumption is that certain coordinate endpoints of one shape need to match the coordinates of another, but I can't achieve that. Using the auto roof function creates a perfectly placed roof with shapes ending at corresponding coordinates. I can't seem to do this with the freehand shapes I draw.

Thanks for the response.
