Can't open 2D export from Google Sketchup about dxf HOT 4 CLOSED

Thank you for the bug report. This looks like another case where the Autodesk DXF spec isn't complete; the spec says 102 codes are supposed to be of the format:

102
{some-string
// a bunch of other code pairs
102
}

But this looks like a specialized shortened version used when only one code pair would be in the group.

I have two questions for you:

1. How were you using this library? NuGet package or clone/build locally? What version/commit?
2. Can you email me a file that leads to this error? [email protected]

Figured about the 102{ stuff from source code, but I'm not familiar with DXF spec. If this VTR thing is uncommon, I can manage without you changing the code. I can just delete those 6 parameters from the file. I tried that and now it works.

I'm using online NuGet version 0.3.1.

Here are both Sketchup file and DXF export file.

FYI, I've created PR #62 which will allow this file to open.

My original guess about the 102 handling was off and the problem was ultimately that the XRECORD object in your file didn't specify the duplicate record handling flag which means a subsequent read of the code 280 pair was mis-interpreted as that which caused the rest of the object to be read incorrectly.

Edit: this also means that to get the proper fix on your end you'll have to take a source dependency and build locally instead of consuming the NuGet package, because there's been a lot of compat work happening since release 0.3.1, including changes to reading in XRECORDs which means I can't take a targeted fix. That and I'm not yet ready to release the 0.4 NuGet packages.
