Few people have asked me on how to do the calculations for sheet metal export option when exporting sheet metal parts to DXF/DWG. Here is one example of such macro  Export Part to DWG Example (VBA)

To make it easier, I've made a calculator to get the required values. Please click on the picture to download the same. I'll update it for future version if there are more options.

Any feedback would help me to improve this.
