Import fail in Sketch Pro 2018


Hi All

I am having trouble importing a DWG block (from AutoCAD 2018) into sketchup pro 2018. I have read prior posts and seen that saving the AC drawing in an earlier format (2013), and exporting the block again, should help solve this. However, this has not worked.

I’ve tried simplifying the drawing ie explode all and removing text, but it still doesn’t seem to be working. I rely heavily on using Sketchup to make 3D models of my designs, so at a real loss until I can sort this! Any help would be greatly appreciated.




There are so many variables with CAD drawings that it’s difficult to know for sure what’s causing the issue. Upload the DWG and someone will take a look for you. If it’s too big to upload, use dropbox or similar and post link.


Hi Eric

Thanks for your getting back to me. I have attached the original AC plan and the exported AC block. I look forward to hearing your thoughts.

First thought. Even though you save the file as an earlier version, do you export the block as an earlier version? If it’s exporting as 2018, I would have thought you cancelled out the backsave…


Good shout Ian. I did think about this, but I can’t find the option to export as an earlier version. There only seems to be an option when saving [as] the whole file.


I am unable to import either of your files into SU. All I get is a blank import window. That leads me to believe the versions you have are still 2018 or later.

I don’t have Autocad but I am able to open DWG up to 2013 version, but I am also unable to open either of the DWG in CAD. I get “unsupported version” message.


Sorry Ian, I uploaded the newer versions without thinking. The 2013 version for the whole file is below, as is the exported block. However, the block may have reverted. I probably just need to find out how to export as an earlier version in AutoCAD. Perhaps I’m on the wrong forum! 18.HTN.402.Stage 2 Concept Plan@A1PL.19.9.18.dwg (1.3 MB)

So numb nuts over here (me) has worked it out. I have to open the exported block and save as earlier version. Thanks for the help anyway guys. It is a bit of a schlep, mind. Hopefully Trimble will make Sketchup more compatible with AC 2018 soon!


Well, both of those files import into SU successfully. But to me they look the same? (nevermind)

You beat me to the open block/save as earlier version thing. Glad you got it figured.
