Characteristic of the present process is thus that generated in response to the respective input, such as a afflicted with inaccuracies sketch, an exact computer-internal representation and the latter is precisely displayed on the drawing surface, and that the development of a construction of the exact representation starts to then to be also implemented in a precise computer-internal representation and displayed on the canvas. By imprecise inputs are respectively corrected by a computer unavoidable and thus any further development of a design based on an accurate computer-internal representation of said previous construction elements, the inventive method allows creating accurate designs where the possibility of error additions is excluded.

Schneller als je zuvor

In conventional methods, however, only one of the required display is each analog representation displayed with the consequence that any further development can lead to a non estimable error addition does not give any precise representation, but of such analogue, and thus starts also from the latter adhering errors, ,. In a thus formed drawing board trace of the pen from the measuring system, which may be a per se known image recognition system is received and visualized by means of the arranged behind the sign plate plotter an exact representation generated by the computer of the sketched image onto the drawing surface, then is the basis for the development of a structure, each step of such a further reacted in the same way in a precise computer-internal representation and is made visible on the drawing area.

Accordingly, any further development is based on an exact representation of the previous development step. A particular advantage of the inventive method and the serving of process implementation tear board is that one, the invention-use designer can work as usual and in contrast to prior systems no influences are present, which could affect the shape and dimensions of perception of a user.

An expedient embodiment of the invention provides that the drafting machine possesses a Linial, each with a x- and y-legs which form a the origin of a temporary co-ordinate system representing corner. In view of this corner construction precise approaching any points on the canvas succeed. In addition to a drawing head three measurement systems known in the art for the detection of angular positions as well as the x and y coordinates can be provided. Another embodiment provides that three auxiliary drives are provided for fine positioning of a selected position by the pin, which travel within a particular capture circle and fix the respective position.

Die Hilfsantriebe wirken auf die x- und y-Koordinaten und die Winkellage. The auxiliary drives act on the x and y coordinates and the angular position. Zum Sichern der jeweils erreichten Position dient eine Bremse. The backup can also be affected through release buttons. Another important embodiment provides that a menu field is provided with a dynamic part of a touch-sensitive graphic screen on the edge of the sign plate, preferably on the right side thereof. In the menu box, important commands are stored, such as required for the next used CAD software manner.

The sign plate represents the mechanically fixed part of the tear board on which the drawing surface is located. These signs surface consists of radiation-transparent material, so that an emitted from the arranged behind the drawing surface Plotstrahl plotter capable of producing a perceptible color change through the sign plate into the drawing area. Ebenfalls im Rahmen der Erfindung kann der Zeichenplatte auch in an sich bekannter Weise ein Digitalisiergitter zugeordnet sein.

Also within the scope of the invention, the sign plate can also be associated in per se known manner, a digitizing.

To prevent a negative influence on the optical path, the surfaces must be flat. When using very high-energy radiation of the character plate body may also have a radio-opaque, but highly thermally conductive layer so that the reaction of a captured on the protective layer thermo-sensitive drawing area is ensured.

When using a measuring system as Digitalisiergitters the impenetrable for electromagnetic waves of high frequency protective layer is suitably provided on the side remote from the plotter side with channels and in the latter, the digitizing grids is accommodated. In the present invention thermosensitive preparations can be applied directly to the sign plate without further excipients.

In such an embodiment, the character plate may have a rough surface which creates an additional scattering of the penetrating Plotstrahls, so that the intensity of Plotstrahls is lowered to a safe level for a user. In order to attach the sign face having paper or foil-like character, in general, problems, the character plate is slightly curved uniaxially according to another embodiment of the invention.

By this measure, a close fit of the canvas is guaranteed at the slightly convex drawing board. According to another embodiment, the sign plate can also its side facing the observer directly carry a sign face having a dye-like character with a radiation-sensitive preparation. This preparation may be removable or supplemented. Yet another embodiment provides that the drawing surface consists of a carrier material which is prepared with a radiation-sensitive substance. In order to improve the efficiency of energy conversion, the drawing surface, as seen in Plotstrahlrichtung, also with an absorbent layer and then provided with a thermo-sensitive layer may be.

Said two layers may be separated by the support material. However, it is essential that first the absorbent in Plotstrahlrichtung and then the radiation-sensitive layer. In the present invention, however, the arrangement may also be such that the absorbent layer, and finally the thermosensitive layer from Plotstrahl first the carrier material, then is penetrated. If the radiation-sensitive preparation is a photosensitive layer directly developing type, this photosensitive layer is disposed viewed in beam direction before the sheet-like carrier material.

The sheet-like carrier material acts at the same time for the ambient radiation of the room as a filter, particularly as a yellow filter. Conveniently, the surface of the drawing surface is matted form.

In order to work according to the teachings of the invention, the path of the pin must be measured. In that regard, in addition to the digitizing an embodiment of the invention, the use of a known acoustically operating measuring system with several microphones before, wherein at least one microphone is connected with the movable drafting machine.

This ensures that an audio signal of a then be inserted, per se known acoustic pin is optimally received.

Another embodiment of the invention is characterized by the use of an optical measuring system with a camera and a luminous stylus which emits a with the preparation of the drawing surface non-reactive type of light. This optical pen emits at its apex a point of light which is detected by the camera of the optical measuring system. The surface portion follows the pen tip in their movements rough and the true position is calculated.

For certain test operations, a further aspect of the invention is that in addition to a Plotstrahl, the tool head emits an unresponsive with the preparation marker beam. Another embodiment of the invention is characterized in that a UV radiation source is used as a light source and that this light source is arranged on the tool head. Instead of a UV radiation source can serve as a light source, laser diodes, which are then arranged likewise on the tool head, in such a way that the emerging from the laser diode beams converge into a focus, which is located in the vicinity of the radiation-sensitive layer of the canvas.

When using laser diodes for guiding the beams formed as a mirror beam guidance means have proved expedient. In the present invention, however, high-energy laser beams can also be channeled through mirrors or fiber optic cable to the tool head. When using a powerful laser beams with strongly diverging beam geometry, the precise positioning of the optical system must be ensured to the drawing board. This can be achieved according to the invention characterized in that the optics of the Plotkopfs opposite the sign plates is air bearing body, which ensures a defined position of the optics to the drawing plate and thus accurate focusing in the drawing area.

With the provided by the invention intelligent drawing board, it is possible to generate a sketch together with associated alphanumeric information with a pen on the drawing surface, said parallel a computer-internal representation is calculated, which is relevant to the progress of work data, which are in particular geometric data These are output on a plotter on the canvas. Thus the sketch and a sketch of the corresponding correct plot without noticeable parallax are visible to the user of such a tear board.

Reference to the accompanying drawings, some embodiments of the invention will be explained below. In schematischen Ansichten zeigen: In the schematic views show: The information thus obtained is processed by an associated computer 7, which thus creates an exact computer-internal representation of a designed on the drawing surface 3 by hand or with the aid of the drawing engine sketch.

Relevant parts of the computer-internal representations are plottered via the plotter 4 from behind against the canvas. The exact computer-internal representation is located beside the sketch quasi parallax before the 2. Learn more about Amazon Giveaway. Set up a giveaway.
