How to Make 3d model from 2d model

The basic tools of all of the 3D modeling software work the same way. we produce a 2D model, or a sketch, which is drawn with vectors. This sketch (2D model), will then consist of precisely definable geometry, which can be manipulated to produce a 3D model, revolved, extruded, swept along a path, or by any other tool provided by the cad software. After a small amount of learning mostly a relatively simple process, though often we are charged a substantial cost from a training provider when we enroll in a course to gain this skill. One of the fundamental blocks of knowledge is to know what makes up a vector as compared to a bitmap, which is an image made up of a very large number of dots. The nature of this bitmap image, and a limiting factor in it's usefulness as a start point to produce a proper mathematically defined 3D model, is that an extremely large number of x and y coordinates are required to define this 2D image and of course as you scale this image up and down there relationship to the zero point, or origin of the x -y coordinates varies greatly unlike the vector based 2D model which our 3D cad uses, where the x - y coordinates are defined by precise math that will stay proportional to the origin. Now being engineers, trained to understand how technology works, we know that running a 2D bitmap image, printed on a piece of paper through a scanner can only produce a digital bit mapped image, not really a 2D model in the cad sense. This makes the scanned image not very usable, so that, with a few mouse clicks, we will end up with a 3D model. Sometimes we can use a program such as inkscape to turn this bitmap into a vector, and as inkscape can export this image as a dxf file, a very cad friendly format. Unfortunately due to the nature of the original bit map image the outputted vector will need much time and effort to turn it into anything useful unless it is extremely simple, and just modeling it directly is probably way faster than scanning, converting and loading into our 3D cad.

So to get to the point, there does not exist, at this time, a magic piece of software, that with a few mouse clicks, that will give us a wonderful 3D cad model, with little effort or skill. There have been many similar questions by many looking for that easy way to go from an image on a piece of paper to an awesome 3D cad model. Being technical people, with an understanding of how things work, to figure this out ourselves should be a simple process, no need to be another on GrabCad to ask the same silly question that has been often asked before. If we can;t work this out for ourselves may be we are not cut out to be engineers or other technical persons, maybe we should have became an accountant instead were too much imagination and creativity often ends up as a fraud case in a court of law

Input the 2D data in nx and do the modelling as required...
I can convert, but the service will be paid...
