1- Decide If You’ll Use Type Or Instance Parameters
Each firm has its own standards regarding their door schedules. An important thing you’ll need to figure out is if you will be using type or instance for each parameter. There is no one answer to this question.
You might normally put all dimensions or materials in type parameters.
When a parameter isn’t directly related to the geometry or the general material, instance is usually more suitable. Instance parameters would include hardware and fire rating.
In the schedule below, we’ve used yellow for type parameters and green for instance parameters. Some of the instance parameters (From/To Room) are built in and automatically generated.
