Hello,

I have noticed that ThinkGeo 13 has much better support for importing .dwg CAD files into the map compared to ThinkGeo 10.

Unfortunately I have recently come across a .dwg file that is unable to be imported into my map and causes TG13 to throw an error.

It seems like it may be related to a bad/invalid value relating to an angle?

It is not particularly urgent as there is a workaround I can do to successfully import the .dwg file by converting it to a different format beforehand.

I thought I would share the .dwg file in question however so that you can take a look at it if you wanted to and help improve the CAD importing side of your code.

I have attached the .dwg file in question (it’s within the zip folder due to being an unsupported file format), and the error that gets shown when I try to import it into my TG map.

[DWG file.zip](https://community.thinkgeo.com/uploads/short-url/r4rQDMpRqhfwm66kixCZPCRClpa.zip) (2.0 MB)

Hopefully this is of some use to you.

Kind regards,

Luke

Thanks Luke,

We appreciate you sharing the .dwg and we will take a look and see if it’s a scenario we can support or an issue in the .dwg. I will let you know what we find out.

Thanks,  
John
