AutoCAD LT Macro/Application

I need a macro or application that will work with Autocad LT. Since AutocadLT does not support NETLOAD command, a .net application is not possible. What I need is a simple macro that will allow me to select what I want on the screen to export to DXF file. I should be able to select say a square on the screen, and when I double right click (or press a toolbar button) then it will export the selected contour to a DXF file. Please give me your proposal on how you plan to accomplish this, and if you have any previous experiences with working with Autocad macros. *Clarifiation. I need this to be a smooth interface between AutoCADLT and a different CAM system. There is an option in AutoCAD to only export selected items. But I need to be able to set colors of the entities, not by the regular buttons, by additional toolbars, and then export selected to DXF. If you can launch another application through the macro, that would be wonderful. The application that I will create will read in the DXF that this macro creates, and creates a part from it for the other CAM system. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
