WinDoor - draws windows and doors. Now upgraded to run on Sketchup2014. Coming soon is a completely new window and door program which works by extruding profiles. The windows/doors are coloured/textured on the outside and hatch patterned on the inside according to the front and back colour/texture on the profile. Section length, glass and spandrel areas and other calculations for the windows will be available. BIM at it's best!
Circle3x3DPoints - draws a circle from 3 x 3D points.
