What I need is to be able to render CAD and PDF design files to my own rendering 3D Canvas so that I can later manipulate them or even extend them on a GUI application. Manipulation would include selection, extrusion addition of more objects using snapping etc that I already support.
From your side I only need the vectorized geometry but instead of outputing this to an html file I need this to a callback API call.
For example I need an API call that will notify me to draw a polyline providing coordinates and a color. All possible vectorization scenarios would be:
2. Polygon (closed polyline)
3. Shell or Mesh
This means that elements like text have to be vectorized and provided as a set of accurate polylines with a reference of course to the original object.
I think you are very close to provide this as an API and it is a must do feature.
