Since forever VectorWorks offers the possibility to show dotted circles around moving light fixtures to indicate their maximum reach. I would like to see an even better version of this in wysiwyg, where the circle is interactive. So when you are placing fixtures, the circle could show as a normal grey dotted line, but when you move the light too close to another light or an object, it becomes red. This could be very useful in tight rigs or when scenery gets in the way. Sometimes it is very hard to judge in the 2d world how close an object is, so wysiwyg could use its 3d awareness to warm the user. Unlike trying to hang a fixture off of a pipe or truss, it should be possible to override the warning though.
This has already been asked for recently. Please search the forums before making an additional post to keep thing streamlined. https://forums.cast-soft.com/index.php?threads/fixture-rotational-movement-range-depiction.1283/
