I am trying to add a curb to a plan, and am doing it by creating another “floor” which is offset from the main floor by 6”. It works fine until I try to create a break in the “curb” by editing it’s boundary. In the sketch below, line “1” is the outer limit of the curb, and line “2” is offset from line “1”. Line “3” is where I want to start my gap in the curb. I can trim lines 1 and 3 with each other, but when I try to trim 2 and 3, I can only select line 3, line 2 is not able to be selected. Hints to correct this please?
