DXF files and VB.net

[Anonymous]

I need to import DXF files using a home grown VB.NET application. What I need to do is:

Open a DXF file

Get access to the drawing entities like lines, arcs, etc.

Get access to drawing entities data like start point x/y, end point x/y, center point x/y, line widths, colors, etc.

I need this info to convert a path of entities (lines and arcs) into code that various robots on our shop floor can use to drive their axes. These are no prewritten software packages that currently exist that do this for these robots.

I do not want to purchase AutoCad due to cost and complexity. We will be using a simpler and more cost effective graphical front end to created the DXF files.

Does anybody have some suggestions regarding API's or SDK's that can be used with VB.NET (or possibly java) that would allow me to open DXF, get entity information. I do not mind paying for a good kit that would accomplish this so I do not have to write an importer myself.

You could look at Blender.org. It has a DXF importer written in Python.

Also there is a project here for importing in .net
