2D CAD Library/ Engine for MFC/ C++

HI All,

I'm currently developing a software for 2D CAD to read, write and displaying (Zooming, Panning and Selection) DXF , DWG and Image view. However the data i want to display is massive and so dense ( around 50.000 - 200.000 object ) So i need a good Display Engine for my project. I build the project with MFC and C++ and some GUI Toolkit component.

Does anyone knows how can i get that kind of engine for C++/MFC? i know there are some good engine, but has been built on C# technology. I also know te library from LeadTool, but somehow, this library is not fast enough to display my project.

any comment will be appreciate.

You are probably looking at a scenegraph.
Openscenegraph has pretty good support, opensg is supposed to be more cad-like but i haven't used it.

Look at NVSG and OpenSG. They are both used heavily in CAD/Virtual prototyping applications.

Openscenegraph is for vissim.

Not free or cheap and I don't work for them but I use their product at work.  HOOPS.  Good support and all round good performance for a 3D library.  It's not perfect but nothing is in this field.
