As an exercise
I am designing this portico with a wood covered casing over a principal glass door entrance to a building.
When I traced the two point curve of the outside the upper part of the plane filled up no problem.
But when I try to trace the matching curve on the inside in the back
only the bottom part (that is supposed to be glass doors) fills up.
I can’t seem to find the spot to snap to along the upper line (where I made the vertical line)
Checked the meeting points at the end
can’t fine where something is not co planar to fill out the upper wood part.
put lines across but it still does not fill up
