Summary
1) Desirable bodies sign:
First we must draw our desirable body in all necessary views faithful to graduation. In most cases a front view, lateral view and a plan view is enough. Body drawing
2) Draw winding up:
To be able to produce the body of paper, the single parts of the body are drawn as a winding up on the paper in the desired original size. Most lengths and measures can be taken over directly from the views. Others must be constructed or be investigated computationally.Winding up draw
3) Winding up print:
On producing the windings up these are printed out. Pay attention to the fact that scaling the printer is properly put, but the parts are printed in wrong size. Winding up print out
Now the drawn or printed windings up of the body parts must be cut out carefully.
4) Windings up cut out:
Now the drawn or printed windings up of the body parts must be cut out carefully. Best of all at first only roughly cut out, and then carefully with look for detail cut out well. Cut out
5) Stick folds prepare:
To be able to join the single body parts, one needs Sticking folds. These are prepared according to demand differently. Just Sticking folds become mostly only in the crease edges folded. Round Sticking folds must be still cut, in addition, in many small segments. adhesive folds
6) Round Sticking folds:
Round Sticking folds an internal one and an external line which are differently long have. This is why the fold will snap with change either stretched or compressed because to themselves with the lengths snap. Round Sticking folds
7) Crease edges prepare:
The windings up are snapped at many places, are folded. The crease lines will fold before him with a knife point under moderate pressure on a smooth and firm base easily carved. Then the paper is a little thinner in the crease line and can be folded so precisely and cleanly.Crease edges prepare
8) Alignment:
The careful alignment at the beginning, is the basic condition for the good and exact fit of the single components of our desirable body. Pay attention to marks, these help in the alignment. If they stick together first only the places in those the marks are. Alignment
9) To join the body parts:
around the windings up prepared now to a body, become the sticking folds with some liquid paste coated and then at the places intended for it stuck together. Pay attention from the outset to the fact that edges and corners lie on top of each other precise and fit to each other. Join
10) Stick:
Adherence has proceeded a material-logical adding of the production engineering.
To stick together enterprise them with it, first the upper points and the lower corners precise. Pay attention to the fact which is properly aimed the body, besides. Stick

Our desirable body
Our desirable body, a quadrangle pyramid with cylindrical penetration, is shown here in front view and under it as a plan view. Because all four sides are identical, we need in this special case no lateral view. On the right of it to the better understanding the body is in a projection in " gentleman perspective " shown. (x axis 45 °; Y axis 180 °; z axis 90 °)
Other projections are a " Isometrie " (x axis 30 °; Y axis 150 °; z axis 90 °) or " Dimetrie " (x axis 42 °; Y axis 173 °; z axis 90 °)
On measure and other detailed data it was renounced in this drawing because of better clarity.
