There is a check box for staircases in Furniture Library Editor 1.6 released yesterday.
For the most audacious users, there's even an accompanying text field to enter the cut out shape of the staircase using the SVG path syntax.
This shape should be closed and fit in a square spreading from (0, 0) to (1, 1) which will be scaled afterwards to the real size of the staircase. The default value:
M0,0 v1 h1 v-1 zBut you can enter a much more complicated shape like the pie matching the spiral staircase available in the default catalog:
M0,0.35 h0.47 l0.375,-0.35 l0.088,0.118 A0.5,0.5 0 1,1 0,0.35 zIn case you enter a wrong shape, it will appear in red in the text field (but don't worry it won't make crash Sweet Home 3D if you don't fix it).
Good luck!
