hi,
we will try our best to get rid of this issue. But as you know there are many things we should think about. Edited by: Jacky-li on Dec 15, 2009 1:55 AM

Hi,
the team will work at this problem as soon as possible;
it does not appear to be related to the flat pattern creation.

Which CAM software are you using?

Thanks,

What is the problem. Is it ---
1) that the bend line projects beyond the contour, or
2) that the bend line doesn't finish at the contour.
I ask as we had a problem with some laser cutting software when the bend line (which was to be etched) finished on the contour line that was to be cut. We solved our problem by writing some VBA code to modify the IV produced DXF file (DXF files are only text files after all) and shorten back the bend lines by a few mm so that the bend line finished before it reached the contour line. Could you cope with bend lines that stopped a few mm short of the contour?

the save copy of flatpattern is the fastest I've found, but to really speed it up you need to create a custom xml file to set your layers and delete the unwanted information. I've edited one to work with Sigmanest and Tops so it does an outer contour and maintains bend center lines, the outer contour is on one layer and the bend lines on another.
save the xml file in the default location, then all you have to do is check the box to use xml
it's saved in your default design data folder under the dwg-dxf folder. the check box will tell you where.
with this file I only have trouble with every hundredth file in the places where mis-formed transitions or cuts across bends have really screwed up the contour. you can edit it to whatever you want though. it's pretty easy to understand from looking at the file Edited by: Monkeyengineered on Dec 29, 2009 7:27 PM

We are using autodesk inventor 2010, and we are trying to export the dxf file to Vbend, which is used for the simulation of press brakes using DELEM controllers.

If anyone knows of a better system to do this, feel free to share.
