3D modeling editor

[Victor]

Hi,

We are planning to implement a interactive 3D model editor in c#.net.
This editor should allow the user to draw different type of graphical
elements like line, triangle, circle ,rectangle and do some operations
like translation, scaling and rotation etc. Similar to UML editor.
Regarding this, can someone share your experience and the best
technology which suits the above requirement with ease to develop and
performance oriented.

My options are
1. GDI+
2. DirectX
3. OpenGL

Please provide if there is some other best technology for this
purpose apart from the above options.
Thanks in advance.

It would probably be easier to use an existing modeler and handle your
needs as data conversion.

GDI+ doesn't do 3D.
