A right and very important realization: In AutoCAD you must, you MUST urgently draw a correct linework/geometry, regardless of what the drawing is supposed to represent - the inner parts of a mechanical pocket watch or the ground plan of a big building. The drawing must be precise, because otherwise a lot of commands in AutoCAD will not work correct: e.g. join lines/arcs into a polyline if they don't touch exact at the endpoints, hatching an area that is bounded by several objects but has (tiny) gaps, sculpt 3DSurfaces into a solid if the surfaces don't describe a watertight volume (smallest gaps will cause a fail) and a lot of others. 

The accuracy with which the real model is later produced is a completely different matter and has no influence on the drawing accuracy required in AutoCAD. 

 

Good luck and success for future projects
