This ArchiCAD Add-On can convert 3D Studio (.3ds) files to ArchiCAD GDL objects. The conversion process can be customized by the user. The conversion process is customizable with the Options command from the Extras>>3DS Converter menu. The user can assign the correct x,y or z instead of the original (x=x, y=y, z=z) assignment. There can be a '-'-sign before x, y or z. For example, when 3ds file is converted from Lightwave, the recommended assignment is: x=x, y=z, z=y.
