I am trying to understand the different types of Light Fixture families, and have a few questions.

First of all, from what I understand, there are 3 different types of lights; Standard, Spot, and Linear.  My questions are:

1. Are there adjustable parameters in the family that define the type of light source?  Or are the parameters internally defined in the light families (depending upon the template used)?

B. Does the invisible line in the Linear template indicate the light source?  Can the length of the light source be modified by simply extending the length and location of this line?

Third. What direction do the angle parameters in the Spot light template refer to (up or down from the horizontal axis)?

IV. Can existing fixture families be changed to a different type of light source (eg. from standard to linear)?

Thanks in advance for any help.

First, I like your number style...

 Second, answers:

1) & IV. The Parameters that define the type of lights fixture are built into the templates.  So you can not make a spot light into a linear fixture via instance or even type parameters once the family is opened in the family editor.

B. My guess would be yes to both parts of this.  You should be able to set up a parameter that can adjust the length of this line (locking align).  I'm not positive about this.  Some quick tests should indicate the answer.

HTH!

You fell victim to one of the classic blunders. The most famous is never get involved in a land war in asia, but only slightly less well known is this! Never go in against a Sicilian when death is on the line!
