| - | ==== Drawing data format ==== | + | === Classes: geometric tolerance (shape, direction, position and run) === |
| - | Various data formats have been established for the digital exchange of →[[en:infra-convert:user:terms#Drawing (technical)|technical drawings]]. Each data format transports at least the graphic information of a drawing printed on paper. In addition, vector formats and especially specially developed drawing data formats store information that facilitates automated readout by computer programs. | + | |< 100% 15% 5% 45% 20% 7,5% 7,5% >| |

| - | Basically, a technical drawing is constructed according to largely internationally defined standards from linear graphic elements as well as text elements. The reader derives the meaning from the arrangement of the elements in relation to each other. However, this kind of interpretation work can only be implemented by software to a very limited extent. For this reason, additional information is stored in drawing data formats, which indicates to a software that the elements belong together and what they mean. | + | ^ ::: ^ ::: ^ ::: ^ ::: ^ ELIAS ^ [[en:infra-convert:dev:export:dfd#K2009]] ^ |

In the early days of CAD, different line widths could only be displayed poorly on the screen using the technology of the time. An ink pen was assigned to a color on the plotter. An assignment table for line widths ("pentable") is usually not exported to the usual exchange formats. For better legibility, #@IC_HTML@# therefore displays drawings in monochrome ("black on white") as standard. | ||
