Ahhh I think it depends on what you're trying to test. I downloaded the dxf file but would not open in QCAD, LibreCAD, DoubleCAD or BCL. Well, I thought, of all the nerve!!
With multiple attempts, I was finally able to open it in BCL and have a look at all the drawing objects. This is not a suitable test dxf file for BCL in my opinion, because:
1. It contains too many drawing objects (499) with lots and lots of duplicate objects.
2. However -- having said that -- this is a suitable dxf file for performance testing with engraving software such as T2 Laser!!!
3. BCL doesn't engrave (currently) so it can't really performance test the file. About all BCL can do with it is to test that all the drawing objects BCL supports handles them OK in the file. So, with that in mind, I have added the missing drawing objects, mainly formal Single and Multi-line Text objects, Splines and Ellipses. See attachment.
I am in the process of finalizing one optimizing feature within BCL before I do one last Save As and produce an additional test dxf file for BCL, but attached is what I've modified your original file down to for BCL.
As I said, your original file may be perfectly fine for engraving performance testing with T2, but I would do a Save As on it as it does have some internal corruption to it structure. @Zax's dxf optimizer may be able to fix this too.
