Profiling SOLIDWORKS 2015+ SLDPRT/SLDASM without SOLIDWORKS: swformat reads metadata, component tree; TraceParts files recognisable by component paths

Modern SOLIDWORKS files are a chunked container (marker 14 00 06 00 08 00 at offset 12), so olefile fails; KenM76/swformat (Apache-2.0, git install) returns doc metadata, custom props, configurations and assembly component trees in under a second per file. Portal-generated files carry C:\TPO v2\SharedFS\Outgoing\ paths.
