Dan Coldrick commented on TIKA-3731:
------------------------------------

related to https://issues.apache.org/jira/browse/TIKA-1735 but that looked to 
also try to include a parser so thought it would be good to split the two 
issues and get the bug fixed.

> The tika DWG reader is only pulling meta data from up to drawing format 
> AC1024  (see code snippet) where it looks to be AC1027 & AC1032 can also be 
> read from the same get2007and2010Props meta data extractor.
> {code:java}
>  switch (version) {
>             case "AC1015":
>                 metadata.set(Metadata.CONTENT_TYPE, TYPE.toString());
>                 if (skipTo2000PropertyInfoSection(stream, header)) {
>                     get2000Props(stream, metadata, xhtml);
>                 }
>                 break;
>             case "AC1018":
>                 metadata.set(Metadata.CONTENT_TYPE, TYPE.toString());
>                 if (skipToPropertyInfoSection(stream, header)) {
>                     get2004Props(stream, metadata, xhtml);
>                 }
>                 break;

>                 }
>                 break;
>             default:
>                 throw new TikaException("Unsupported AutoCAD drawing version: 
> " + version);
>         } {code}
> Looks like the case statement just needs extending and for examples files to 
> be created for AC1027/AC1032.
