Export with Alpha Channel

GDL Enthusiast



I am trying to export from the floor plan with an Alpha Channel. Every option I have tried of the export results in an image without an Alpha Channel when re-opened. I have tried all image types, Tiff, Jpg, Png, exported with Alpha channel or high quality with Alpha Channel. I have tried exporting the image with a transparent fill in place, and also with a fill set to background. Still no Alpha channel present. Is this a known Archicad bug or am I doing something wrong?


Many thanks in advance!

If you can elaborate the use of the alpha channel, say looking for transparency or bump, I may be able to help you. Also any end product image you can provide?

Hi Rajesh,


Thank you for responding. Attached is a screenshot of what is on the floor plan before export. Attached is a screenshot of typical export settings with Alpha Transparency. Lastly attached is the exported image (zipped as this site wont allow uploads of a TIFF file). I cannot seem to find any other options for export and would welcome help. 


Ideally I would like to export anything I create on the floor plan e.g. a site plan or a small detail drawing, and with that export it with a transparency. It is great for post processing work in image editors. Thank you again for responding and all the best!
