I am currently working with the student version of Archicad 26 and the add-on for Cinema 4D. For Cinema 4D I use version 2023.
I read in the forum that when exporting in Archicad's .c4d format there is a choice of whether to export as a class or a layer. Is it possible that this is not possible with the student version? In addition, the scaling of the model is not correct when importing into Cinema 4D, is this related to the use of the student version?
