Automatic Symmetry Detection

Many manufacturers provide EULUMDAT files that are coded has having no symmetry, or Symmetry.NONE whilst the underlying data actually shows that the photometric distribution is symmetrical along one or more axes. When you as a designer are looking for a symmetrical distribution, this can be quite annoying or confusing.

Enable the Sandbox checker in the Preferences for global reach...

Set as preferences

or select a project and set it in the Properties.

Set as project properties

In both cases a rebuild will occur and the Problems View will show the files with the selected problems.

Symmetry warning
