I have intermittent problems exporting PDFs from Layout.
The reseller told me that the problem lay in me importing pre 2020 models into Layout.
Over writing the whole model with a 2020 version is not enough.
The only way to make everything work is to systematically go through a pre-2020 model to find which group, component, line or imported base drawing is at fault. When a model might contain thousands of elements this process can take hours. That’s just insane!.
I don’t believe that for a second. I’ve used models created in earlier versions of SketchUp in LayOut 2020 and had no problems with exporting PDFs. I’ve also opened older LO files and exported PDFs from LO2020 as well.
I expect there’s something else going on. Perhaps you could share a problematic LayOut file?
I had to revert to a printer to get drawings out but I am using Layout’s for this exercise. The drawing relates to views only with no dimensions shown.
I have found a north signifier at the edge of the SU view - wondered if that could be the problem.
Does it fail even if you start a new file using your A3 template and try to export an empty page with only your titleblock etc? I am starting to suspect an issue with your template. What fonts are you using? What happens if you change all your template text into something boring and bog-standard like Arial, with no effects?
Your profile says you are using SU 2018 under Windows 7. Did this issue arise on upgrading to version 2020? Did you also upgrade Windows?
To answer your question further. This problem only occurred when I installed SU pro 200 in a new Windows 10 machine.
With the time that this problem has been going on without a fix I have decided that for the few times that this does occur I will use something like Cute Writer.
