Diptrace generated DFX file help needed

[boylesg]

Having trouble getting my head around the following DFX file.

First of all, if 0\nSECTION\n pairs with 0\nENDSEC\n, what does 0\nSEQEND\n pair with?
And what does 0\nPOLYLINE\n pair with?
What are Edge_Bottom and CONTINUOUS?

I have tried looking at the DFX specification but the problem is it doesn't include examples and it contains a lot of other confusing info that is irrelevant to my particular DFX file.

Need to understand the DXF file syntax, particularly the group codes.

Applying it, you'd know that Edge_Bottom is a layer name and CONTINUOUS a line type.

I think, the DXF polyline example is straightforward an can be decoded almost intuitively with DXF spec at hand.

What do you want to achieve?

If you can find one an Autodesk Autolisp manual would help your understanding, or just look for DXF format somewhere like this maybe..

10, 20 are co-ordinates, etc. etc.
