While exporting elements in 3D to AutoCAD a huge file set is being generated. In detailed export mode a 3D-modell is created for every profile and every gasket. In doing so, it can happen quickly that in case of a 50m * 15m curtain wall more than 25000 objects accumulate, consisting of several hundreds of areas each.
The export of a complete curtain wall with all details can thus take some time.
For big curtain walls it is therefore recommended to use the much simplified export mode, which is a lot faster. In the simplified mode, profiles are exported with a highly simplified contour line (hence the name), making the data volume to process significantly smaller.
