Help with Acad generated Dxf file

honoluludesktop

Although I utilize Dxf in my work, I do not use AutoCad and the Dxf files that I generate differ according to the application creating them. I need a Dxf generated from AutoCad as follows:

A block consisting of 6 rectangular closed polylines in the form of a 12"x12" cube with a line on the top surface.
A block consisting of a circle 12" in diameter with an arc in it.

I need to know which version of autocad is used for this export, and would appreciate anyone that can post this file for me.

ok here you go... hope this is what you want... let me know if it works.

Autocad 2010

HD 1 & 2

Krisidious

is this what you want? this is Number 1.

if you could give me a screen shot of what you want I can put it up.

edit. ok I see it now... give me a minute.

Hi Krisidious, Thanks. I can work with them. Interesting, none of my apps can read the files. Perhaps I require Dxf from an earlier version. Since I can't yet view them, I am assuming that each file contains one block; one the cube, and the other the circle.

He can save as an earlier version DXF - e.g. 2000 ?

here they are exported to DXF 2000

Acad 2000 DXFs

Hi Krisidious, The 2000 files opened with all of my apps., but I can use both of them, thanks! Upon visual inspection the Dxf models contain lines, 3d faces, circles, arc, but only a few polylines. I didn't take into account how drawings are made in AutoCad. Perhaps there is no specific tool to create a polyline, and thus the model consist of 3dfaces. Thanks again, these are of help to me.

Well, I spent the day looking at the way various applications read and write dxf files, as well as the differences between Acad versions.

My own Cad program outputs a dxf that is no longer compliant with Acad v 11 (maybe not even since 2000). But fortunately, it hasn't affected my work. I have been writing a SU plugin to modify my Cad2Dxf output in order to improve its performance. As long as I was doing this, I thought I might be able to post a DxfIn for SU-free users, but have discovered that there are too many considerations, requiring rewriting my code to accomplish even a very basic version of this. Good thing for me that my Cad2Dxf is easy to understand.

Thanks for the support everyone, hopefully I will finish soon:-)
