Originally I was trying to look for a specific method that required using front and side view drawings on a tutorial I came across around the years 2000 - 2004, but was unable to find that tutorial. However I did find some useful techniques/methods/programs that were just as good with using one or several background images. Such as the following:
1 - Extruding a simple mesh or vector graphic in a 2D or isometric view.
2 - Smoothie-3D, One 2D picture to create model from, then import into Blender.
3 - Regard 3D, by using multiple views to create a model and bring into Blender.
4 - Kinect with 3D Scan app, then work on you file in Blender.
5 - 3Sweep, Not commercially available to the public yet.
6 - PhotoAnim 3D, you can use one 2D image to work from.
7 - ZBrush, Use their Concept Sculpting method.
As for the technique I was looking for, it was along the lines of the Concept Sculpting method; but using the lines and shape of the two drawings as guidelines for the pen, inflate, deflate and grab tools to transform your 2D drawing on a plane or cube into the 3D object you wanted.
Hope this info helps those that are trying to turn their 2D drawings into a 3D object.
If you have a better method or more to add to the list, let us know.
