DPlot

Good evening and greetings from Ottawa!

I have a rather strange workaround that perhaps Dplot can help with. I need to convert a photo(jpg) to a format I can use on a CNC router.

I can convert the photo to CSV, massage it with a macro (in Excel of all things) and reproduce the photo precisely as a grayscale DPLOT contour plot. It is the next step that I would like DPLOT's help with.

Any suggestions on an export strategy? The grayscale is already enough to provide the relief information I need.

Thanks for your patience with this odd request. If it works, I'd avoid a significant CAD upgrade cost, so fingers crossed....

Cheers

The ultimate answer here is no, sorry. DPlot won't produce a DXF file and it would require reworking how contour plots are drawn to get there (and that won't happen). The contour lines are not continuous, which is what you'd need. Instead what you're looking at is contour line segments within each grid triangle.

But...

I can convert the photo to CSV,

Maybe you've missed it, but you can import your JPG image directly into DPlot and produce a surface plot if you've installed the "Bitmap to 3D" plugin. This will save you a few steps, but again - it won't get you any closer to a DXF.
