Hello
I am trying this plugin for the first time, i'm not a huge user of sweethome 3D so maybe i made a mistake, but i can't seam to have the wire go to a negative level ?
Like from the ground floor to the frist floor, no issue, but going down to the "basement" it won't do it ?

Can someone please ...
