Hi,
Progecad simply does not create an identical r12 output to the native acadr12 dxfout command.
This is the same for the many convertors that I have tried.
I cannot change the utility routine, the company has gone belly up and the routine is actually a suite of software designed to create a digital terrain model. The suite of routines that demand the initial R12 dxf file of the contours works really well for us in our style of work where it creates a VERY smooth representation of the undulating surface model.
Surely there is a utility or convertor out there that will take a r2004 dxf output and change it to what was an r12 output, they all say they will but when you open the resulting file it does not look anything like the old r12 output, there is a huge amount of r2000+ stuff within the file.
One thought I have had relates to a utility that first attacks the r12 dxf file in that it prepares the files necessary for all the other routines in the software to work.
The routine is an *.exe file, I do not know how it acts on the dxf file however I suspect that it extracts the vertex data points and arranges them somehow. If someone knows how to crack into an exe that might be a help to find out what it actually does to the r12 dxf.
