Importing freehand art

Postby demackison » Wed Mar 04, 2015 4:28 pm

Is it possible to import a freehand line drawing or other black and white art and then pad or pocket it in order to create something like engraving or inlay?

If so, how?

You can try using Inkscape, or other like vector graphics program to create a path from your art and use the resulting 2D geometry to then make faces and Extrude. You might also find something like this useful - Macro FCTexture

I have a little program that can convert art to dxf files, but have had no luck modifying anything that freecad imports in any way.

For an engraving, you may want to try this:

You'll need to convert your image to a .bmp

Using Inkscape and converting to a Path and saving in SVG format is probably a better option than using dxf. Personally, I try to avoid the dxf format like the plague that it is. You can find Inkscape here - https://inkscape.org/en/ - free program.

I don't understand how to use it yet, but it looks like that macro is exactly what I am looking for. Thanks.

You're quite welcome. And I should note that the macro is very CPU intensive...
