hi @dale, first of all thanks for this great amendment, i would plead for it to become a regular rhino command, it is really helpful and from what i see actually tosses illustrators vectorizer straight from the ledge. at least in regards of line drawing of course, the quality is really good and it is a very fast and simple process. maybe having a hatched output with different segments from the color shading could even top it.
anyway two requests beside that
corner rounding could get an angle limit option. sometimes i want to keep hard edges while smoothing others with a lower difference in angle.
being able to keep the input image as a texture below the existing curve and maybe even to create a solid extrusion with the image on top.
