Pigtail Mesh & Explaination

[hippyau]

Is your feature request related to a problem? Please describe.

Table 32. Model Attributes

PrimitiveType “Pigtail” is referred to in the specification, but no explanation of what it is nor a mesh is provided.

Describe the solution you'd like
A clear and concise description of what a pigtail is, along with a mesh provided for it.

Describe alternatives you've considered
I've looked at another pigtail mesh, which appears to be a cube? I understand it is the back of a fixture where the IO connects, but I could be wrong, as it's not described.

The way I understand it, the Pigtail is just a Geometry for all IO Connectors. Basically the Panel with all Connectors of a Fixture. And because the Connectors aren't modeled the Pigtail also need no Model or just a cube.

Cheers, yep thanks. Just that Pigtail is defined as a PrimitiveType with no explanation that the primitive shape is a cube or whatever.

| PrimitiveType      | Enum | Type of 3D model; The currently defined values are: “Undefined”, “Cube”, “Cylinder”, “Sphere”, “Base”, “Yoke”, “Head”, “Scanner”, “Conventional”, “Pigtail”, "Base1_1", "Scanner1_1", "Conventional1_1"; 

Revision history shows:

## Version 0.87
[......]
 - Pigtail position should not be specified in 2D or 3D files anymore.
    Instead of it should be created a general geometry and linked to a
    model with primitive type “Pigtail”;

[Verschwiegener]

Yeah i think the Mesh shape is irrelevant the Pigtail is more just the Name for a Geometry of IO Components
