Dsignio technical drawing Autocad and Autocad is a tool .-, paper, and rotring stud, we will use to make our technical drawing.
I am very surprised at the number of people who gets to learn Autocad without having a minimum of technical drawing idea. You can not try to build an icosahedron or if you represent geometric figures do not know what is a projection on the ground and a lowering of the shaft.
Many people learning a course they think they can be unemployed draughtsmen. Actually first studied technical drawing and then choose the tool, Autocad, Archicad, Revit, Microstation, Max. (You can not make the idea of \u200b\u200bthe number of people who are not able to model accurately and precise geometry in Max).
The technical drawing is the necessary representation of anything physical on 2D paper. Hence lies the complexity, the physical often 3D and this transformation information is lost. We use flat projection (isometric, cavalier) to address the lack of depth (Z axis) or tapered (to make compelling presentations and visual). I can not imagine a realistic rendering without having conical projection.
The legislation also uses technical drawing (standard way of representing things) and each sector has its own country and change its rules.
With a compass and a ruler can draw everything, and that we use in Autocad the circle and line. Now you need to know to use them and do not have the appropriate technical drawing skills, then we will do wrong and give shots in the dark (losing time from lack of occupation).
In class with my students, showing them exercising missing for technical drawing tangents (not to draw them that it's almost automatic), but for calculations with proxy data. And other things like that, not only for drawing but also to see that one dimension is wrong.
Autocad blocks should be using technical drawing symbols to represent repetitive elements in the drawing.
So if you want to learn Autocad should soon learn technical drawing or linear.
