Hello All,

Need some solution for conversion to DXF from DRW.

We are working in Inch. I have all models in Inch and when I am saving Creo drawing in to DXF, my dimension are not correct.

for example. if I have dimension 100 Inch in Creo It becomes 2540 Inch in DXF. So basically my dimensions are multiplying by 25.4 while conversion.

please find attached creo and dxf files for same part.

please give me some solution to this issue.

Thanks

Brijesh,

I apologize ... my first response had to be confusing for you.

1.] I opened the drawing and modified detail settings using the following procedure

File > Prepare > Drawing Properties > Detail Options > change > click Open a configuration file button and choose DTL file

Some DTL files are located in Creo 2.0\Common Files\M030\creo_standards\draw_standards directory, I used standard_in.dtl in my test.

2.] My first DXF file was wrong because I missed that your view has the scale 0.075.

To output this view in 1:1 scale I set config.pro option dxf_out_scale_views yes

3.] I turned drawing format off and exported t001979_z01.dxf file. It contains $INSUNITS set to 1 (inches). Therefore I hope it is correct .

Welcome to the forum, Brijesh.

This is not a normal case. I have often exported and re-imported inch based files and it works correctly.

Please make sure that the part file is inch-units; the drawing file is inch-units; and the DXF export is inch-units.

The drawing scale should be a hint as to what the displayed units of the drawing are. Also remember that the drawing exports to DXF as 1:1. Therefore, a scaled view will be according to the drawing's view scale.

If you would like, you can attach the file to a post and someone will have a look at it. I cannot open academic file but I can open full version files in Creo 2.

    You can attach files if you open the Use advanced editor.

    How are you importing the file and to what program?
