Improved IES-EULUMDAT conversion in EulumdatTools 0.13.4.v20150423

A new version of EulumdatTools 0.13.4.v20150423 was published on April 23 at

Conversion options

IES to EULUMDAT and EULUMDAT to IES conversion was improved:

  • There is an option added to swap the length and width of the IES vs the EULUMDAT file. This is selected be default and makes the converted files more in line with the respective standards.
  • There is an option added to rotate the Light Distribution Curve by 90° to allow for differences in US and European roadway lighting standards. When converting from IES to LDT there is a 90° clockwise rotation, when going from LDT to IES there is a 90° counter-clockwise rotation. Note that after rotation the resulting file has no define symmetry. Missing symmetry can be detected and corrected with the experimental Sandbox feature.
  • Before checking or converting a number of pre-flight checks were added to reduce the number of Error messages presented to the user. Such errors are now shown as file errors in the Problems view.
  • Lastly a nasty bug was fixed that disabled the whole Eulumdat validator, when the Sandbox was not present or no Sandbox validators were selected. Mea culpa, mea maxima culpa.

I would like to thank Mikulas Parma of ROBE Lighting s.r.o. for bringing these issues to my attention.
