hi,
we are using recent dwgdirect libraries in our product for importing dwg/dxf files.
we have some customers who have very simple dxf files that did not come from autocad that have some of their x or y coordinates in the format.
for example:
======================

entities
0
line

57.00578033447266

=========================
you seem to interpret the "d-03" the same way that autodesk does, which of course is good....
however, some systems seem to ignore the "d-03". unfortunatly one of our customers has 1000 of dxf files where they would like us to also ignore the "d-03".
certinaly we could just strip off the "d-03" ourselves in a pre-process, but we do have a few questions.
a.) do you have any idea what the "d-03" is all about?
b.) is there a switch or can there be a switch to ignore this?

sorry we had it a little backwards, this is the correct post.

certinaly we could eventualy figure out what the "d-03" means and massage the dxf file ourselves in a pre-process, but we do have a few questions and are hoping you can save us a bunch of time.
a.) do you have any idea what the "d-03" is all about?
b.) is there a switch or can there be a switch to interpret this?
i think the author of program writing such files made a mistake having used "d-3" instead of "e-3" which means decimal exponent.
3.5e-3 would mean 0.0035
surely we need to interprete double values from dxf file as autocad does.
