how to draw 3D arcs

how can i draw 3D arcs of any angles so that i can attach long bars at their ends to make a structure. i have drawn them using directX but it is taking too much time which i cant afford. pls tell me some ways to do that.


If you put your question clearly, people may reply to it.

As i understand your question - u need 2 lines draw in 3D and joined by arc?

As for design it is simple matter of drawing 2 lines and then find distance between two to compute radius and draw the arc (choose ur method of drawing).

Sorry if it does not reply to ur question - BUT explanining exact question may help us to reply.
