This tool can be used to convert CAD lines in floor plan view into 3D architectural walls. Two parallel CAD lines can be converted to straight walls.
Select Building / Wall / Walls on DWG drawing
Click near to the wall starting (1) and end point (2), then on the opposite side of the wall (3). The wall appears in the 3D view.
If the wall joints in the 3D model are incomplete, choose the L or T wall connection options from the toolbar appearing at the top of the ARCHLine.XP application window, and join the walls properly.
