5.12.3.1.5. Classifying characteristic curves

Characteristic curves play an important role in various fields (e.g. electrical engineering, control engineering [e.g. valves], etc.).

A new CNS class (CNS_CHARACTERISTICS_GRAPH ) has been introduced for classifying characteristic curves. A characteristic curve can be described using the associated features.

Following figure exemplarily shows the class with attributes and two instances. The attributes can be manually filled; however, normally the are imported in automated processes (e.g. from VDI Excel data).

Example with 2 instances: Two diagrams will be created accordingly.

The individual attributes:

  • Name of the X axis

  • Name of the Y axis

  • Name/ID of the Curve / Name of characteristic curve

  • Group of the Curve / Name of characteristic curve group

  • Interpolation type of the Curve

    Value range: INTERPOLATE | no entry

    When using INTERPOLATE the points will not be directly (linearly) connected, but with a kind of spline.

  • Stepping distance in X-Axis

  • Start value of X-Axis

  • Comma separated list of Y values / y-values

If the corresponding classification data is available, the existing characteristic curves (in example 2) are displayed in PARTdataManager (or other platforms) are displayed in a separate docking window.

Following figure clarifies the relation between depiction and individual attributes in color.

Y-values are inserted in the respective attribute separated by comma from left to right. Then the curve is automatically generated, beginning at the specified starting point and progressing with the specified step width.
