Name of Dynamic Block Inserts about dxf-parser

[Serthys]

I tried launching the three-dxf sample with the test file and I can see the correct name shown.

Maybe the name '*U146' you see there is Unicode?

If AutoCAD shows different block names then we may need a sample file. I don't know if it's stored in extended data or a standard dxf code/value pair.

I investigated this a bit more.

This is my understanding. When inserting a dynamic block, AutoCad anonymizes the name (*U... like name). However, if you use the BLOCK_RECORD table in the TABLES section, you are able to following ownerHandles to link a particular insert --> block (anonymized name) --> base block (which is named).

I extended the version of dxfParser I had to also parse the block record table which helped with this investigation. More than happy to open a PR for this, but perhaps later versions already have this?

Thanks again!

Ah, I see. A PR would be great. There hasn't been any other development on the BLOCK_RECROD table. I'm a little behind on maintaining this repo, but I've been making bits of progress lately and hope to bring in some PRs soon.

can you share your code, thank you! @pranavramkrishnan
