Looking for a CAD component

[Alex L]

Hi
I am starting a C# Win Forms application for simulation of a special vehicle recovery winch. I need a component for 3D geometry manipulation and drawing.

I have narrowed down to Eyeshot (CAD components for the Microsoft .NET Framework - devDept Software) and DG Kernel (Digital Geometry). Have anybody compared these? Both look pretty large.

Any help would be appreciated
Thank you
