Since I didn't get any reply from the Support to this question, I just re-post it:

https://community.dialux.com/get-support-with-dialux/post/how-to-export-workplane-and-included-calculation-objects-into-a-dwg-file-MComOtxEbqzoHki

So I would really like to export the calculation objects/surfaces along with the workplanes. The space is a car park with an automatic workplane and I added calculation surfaces to DDA car parks and vertical illuminance. When I export to dwg, I get only the results on the workplace, however there is a note that every result exported but not shown... Where can I find the not shown results in the dwg file? ... or how to export to get all the results??
