To start a family component, you need to know what you want to do! It's stupid to say! Your ideas
determine how to approach the creation of the family.
1 - Making a sketch, collect the material on the item (photos, DWG, technical documentation ...)
To better understand the achievement of an item, nothing can replace a good drawing hand! Also, it is good to sketch (more) situational element.
Sketches should show the building geometric element and the future parameters. This exercise
sketches become more fluid after having made several Revit families.
2 - Asking the right questions:
- What are the dimensions may vary? Revit is a parametric software. This term hides including the ability to manage different length values on the same geometry. Must manage a catalog of types? ; Either the item is fixed element requires the axes of rotation?
- How element should appear in different views?
3D representation, seen in plan, section, elevation ... detail.
- What is the origin of the item? The choice of the insertion point of the element is important because it will determine how to use the item in the project. Once the family used in the project, it will be advisable to change the insertion point.
- element it requires a host?
Families standard component can be constrained to a host: wall, floor, ceiling, roof, front line, levels or free.
Choosing a host is irreversible and determines its mode of insertion into the project.
3 - What's this?
Obviously, the category of object is determined. If you're familiar with Revit, it is easy to determine as the family type. Families of standard components are made from templates. They are working environments whose contents vary depending on the selected category.
Below is a flowchart templates families in Revit Architecture 2011.
4 - The template family
all starts here by choosing the template. The above three points should guide you.
What is a template?
A template includes a family environment to create a family: there are a host (wall, floor, ceiling, roof, front line or two levels) or without host families freely insertable into the project. The template also has at least two planes of reference defining the insertion point of the element. Parameters can be preset. Then last parameter, the template determines the category of family member. Family type can be changed while the host is not interchangeable.
Depending on the choice of the template, you must categorize the element:
The following diagram shows the possible categories based on templates.
For everyday use, use the predefined templates.
categories of families outside Revit Architecture 2011
| MODELS | ANNOTATIONS |
| management RPC format * ** specific template with two levels | * prefer templates cartridge |
Thus, purely theoretical, it can be considered 20 categories of model (CAR) x 8 or 160 guests creation environments families! (Without taking into account the specific families templates)
must also consider the possibility of using the categories of other disciplines:

A template file has the extension RFT family ...
That's the second post on the topic of families. If you have comments, questions ... I'm all ears.
