G-code importer and re-exporter Add-on for Blender.

G-code gets converted back to a mesh and can be modified with all of Blenders modeling tools.

Besides having vertex level control over the extrusion path, the Add-on allows you to create texture-based 'Flow' and 'Speed' weight maps using Blenders vertex paint mode.

Concept of weight maps can be extended to other G-code commands as well. By default every import also creates a vertex color map called 'Tool', which depending on the underlying color, will insert a different G-code command for each color.
