How do you apply material to rails?

[CAtDiva]

In the dialog where you define the rail height & size, etc., one of the other columns is "Material"

Some of the parameters are in the edit rail dialogue, sometimes you need to see what family is being used and go to it in the project browser and right click - edit type properties.
