I've got a vb.net program that reads coordinates in from an excel file. It places blocks (dwg file) that are called into autocad at the coordinates read from the excel file.
The program appeared to function well until I stumbled across an issue with the generated autocad drawing. Once the program is complete and all the blocks are drawn in autocad I can save the file as a .dwg file and open it again without issue. The problem I'm having is when I save the file as a .dxf file (2000, or 2007 version) and try to open it again in autocad, I'll get a message like the following:
Error in BLOCK_RECORD Table
Invalid symbol table record name: "" on line 1824.
Invalid or incomplete DXF input -- drawing discarded
I really don't even know where to start looking to resolve this. Why would the .dwg file be fine (or so it appears) but the .dxf file has this issue??
