0.6.0 (29.04.2022)

This release includes major changes to the handling and support of units in the API and ASDF schemas. All classes now support and require quantities where appropriate. Plain numbers without units are no longer supported and will raise an exception. If the number is truly dimensionless, you still have to wrap it with the quantity class weldx.Q_ like this:

my_number = 42.0
my_number_wrapped = weldx.Q_(my_number, "meter")

Furthermore, a new class called GenericSeries was added. It provides a common interface to describe coordinate-based data either by discrete values or mathematical expressions. A built-in mechanism lets you derive specialized series with specific requirements. For more information, have a look at the new tutorial .

Added

  • DynamicShapeSegment [{pull}713]
  • SpatialSeries and DynamicTraceSegment [{pull}699]
  • first draft of the multi_pass_weld schema for WelDX files [{pull}667]

Removed

  • removed access to WeldxFile.data [{pull}744]

Changes

  • The wx_property_tag validator now also accepts lists of different tags. [{pull}670] When multiple tags are passed, validation will fail if none of the supplied patterns match.
  • Due to a pandas update, using the + operator with Time and either a pandas.TimedeltaIndex or pandas.DatetimeIndex now only works if the Time instance is on the left-hand side. [{pull}684]
  • LocalCoordinateSystem and CoordinateSystemManager now support pint.Quantity as coordinates. Types without units are still supported but are deprecated. [{pull}683]
  • Renamed show_asdf_header of WeldxFile to WeldxFile.header. [{pull}694]
  • WeldxFile.custom_schema now accepts an optional tuple with the first element being a schema to validate upon read, the second upon writing the data. [{pull}697]
  • Reshape SpatialData coordinates to (-1, 3) before exporting with meshio for compatibility. [{pull}723]
  • SpatialData, LocalCoordinateSystem and CoordinateSystemManager now require units [{pull}731]

  • CoordinateSystemManager can now delete already assigned data with CoordinateSystemManager.delete_data. {issue}644 [{pull}645]

  • improve dimension handling of SpatialData [{pull}622]
  • The MathematicalExpression now supports xarray.DataArray as parameters. Furthermore, multidimensional parameters of a MathematicalExpression that is passed to a TimeSeries are no longer required to have an extra dimension that represents time. [{pull}621]

  • welding_current and welding_voltage in the single-pass weld schema now expect the tag "asdf://weldx.bam.de/weldx/tags/core/time_series-0.1.*" instead of "asdf://weldx.bam.de/weldx/tags/measurement/signal-0.1.*" [{pull}578].
  • Geometry.__init__ now also accepts an iso.IsoBaseGroove as profile parameter [{pull}583].
