Simplify your Families, Nest itWritten by: Bill Knittle, Synergis Building Solutions Engineer

Did you ever notice that the content provided with Revit Architecture tends to shy

away from how manufacturers offer their product? Take a door for example. A

manufacturer offers a variety of sizes. A Revit door Family also offers a variety of sizes.They are known as Types. The difference lies in the panel styles. Revit families only

offer one panel style.

Ironically, Revits door family template offers a great starting point for creating asimplified series of door families for your company.

Start by creating the Hostfamily. To create any type of parametric content forRevit, begin with a template. Revit ships with several specialized family templates.

1. Click on File>New>Family2. Select the Door.rft family template.

The template will open with multiple views of the family.

3. Save the new family as a manufacturer's name. For example ACME SingleHinged.

Note: It may be beneficial to create a directory structure whereby the Nested

families are a sub-directory of the Host family.

Parameters already exist in the family that control several settings of the door.

These parameters can be viewed in the Family Types dialog.

4.

Select Family Types in the Design Bar.

Height, Width, and Thickness will play a large factor in the creation of this

specialized family. These three parameters control the door panels overall dimensions.Now, begins the stage of the process where you create the Nested family. Again, you will

start with a family template.

1. Again, click on File>New>Family2. Select the Door.rft family template.

Note: The Door family template has within established settings for Object Styles.

3. Save the new family as a panel style. For example Single Flush.Note: Recall the file directory structure? Save the panel styles which will be the

Nested families in the sub-directory folder of the Host family.

Before creating the door panel, some house-cleaning is required to rid thetemplate of unwanted geometry and parameters. Specifically, you must delete the trim

solid extrusions and their parameters.

4. Maximize the Ref. Level view.5. Select each trim extrusion and delete it. Also, delete the flip symbols.6. Select Family Types in the Design Bar.7. Select each parameter under the Other category8. Click the Remove button under Parameters. ClickOK.

Note: There is no need to have symbolic linework in the Nested family. You will

leverage the existing ones in the Host family.

9. Double-click the Exterior view in the Project Browser.10.Delete the opening, swing lines, and equality dimension.

11.Double-click the Ref. Level view in the Project Browser.12.Select Solid Form>Extrusion on the Design Bar.

13.With lines, draw a rectangle to fill in between the two vertical reference planes.Do not lock any of the padlocks. This will be done later.

14.Select Extrusion Properties on the Design Bar.15.Under Identity Data, select Panel from the Subcategory pull-down. This will

allow you to control the visibility of the panel separately from the family. Click

OK.

16.ClickFinish Sketch on the Design Bar to complete the door panel.17.Click the Dimension tool on the Design Bar.18.Create a dimension to indicate the thickness of the door panel.


5/11


19.Select the new dimension.20.On the Options Bar, select the Label pull-down.21.Select Thickness from the list. This will associate the parameter to the dimension.

22.Select the Align tool on the Tools toolbar.23.Select the left-most vertical reference plane.24.Then, select the left side of the panel extrusion and lock the padlock.25.Repeat the process by aligning the right side of the panel extrusion to the right-

most vertical reference plane and locking the padlock.

26.Double-click the Exterior view in the Project Browser.27.Select the Align tool on the Tools toolbar.28.Select the top horizontal reference plane.29.Then, select the top side of the panel extrusion and lock the padlock.30.Repeat the process by aligning the right side of the panel extrusion to the right-

most vertical reference plane.

31.Save the panel family.


6/11


32.Select the Load into Project. This will load the panel family into the Host.

The final step of the process is to insert the door panel as a Component. Then,

you will associate the parameters of the nested panel family to the host familys. Finally,you will create the symbolic linework of the plan door.

1. In the Host family (ACME Single Hinged) select the Component tool on theDesign Bar.

2. Insert the Single Flush door panel family into the opening of the doorway.

Note: If you recall, the Nested door panel family has a Thickness parameter. The

Host family has the same parameter. However, there is not a label indicating the

parameter in the Host family. You will need to create it.

3. Select the Dimension tool on the Design Bar.4. Create a dimension to indicate the thickness of the door panel.5. Select the new dimension.6. On the Options Bar, select the Label pull-down.7. Select Thickness from the list. This will associate the parameter to the dimension.

8. Select the Align tool on the Tools toolbar.9. Select the center vertical reference plane.10.Then, select the center of the panel extrusion and lock the padlock.

Now that the door panel is located and constrained to the opening, you can associate

the nested panel parameters to the host parameters.

1. Right-click on the door panel.2. Select Element Properties.3. Select the Edit/New button in the Element Properties dialog box.

4. In the Type Properties dialog box, select the small button to the right of theThickness parameter.

5. Select Thickness from the list within the Associate Family Parameter dialogbox. ClickOK.

Note: By associating the parameters of the nested family to that of the host family,

you can ultimately connect the two parameters together.

6. Repeat the process to link the Height and the Width parameters.7. Click the OK button to return to the Element PropertiesIf you plan to control which nested panel is visible, you need to create a parameter to

control its visibility.

1. Select the small button to the right of the Visible parameter.2.

Click the Add parameter button in the Associate Family Parameter dialog box.

3. Enter Flush Panel for the name of the parameter.4. Select Graphics for Group parameter under. ClickOK three times.

5. Double-clickView 1 from the Project Browser.6. Select FamilyTypes in the Design Bar.7. Change the values for Thickness, Height, and Width.8. ClickApply to test the parameters.9. Change the values back to their original values.


9/11


10.Select the panel one more time.11.Select the Visibility button on the Options Bar.12.Clear the check for the Plan/RCP checkbox. ClickOK.

The last part of the process is to create the symbolic linework of the door panel

and swing.

1. Select the Symbolic Lines tool on the Design Bar.2. Select Panel [cut] from the Type Selector.3.

Select the Draw button and pickRectangle for the shape designation on theOptions Bar.

4. Draw a rectangle 3-0 tall by 2 thick off the right-most vertical reference plane.5. Lock the two padlocks as indicated.

6. Select Plan Swing [projection] in the Type Selector.7. Select Arc passing through 3 points for the shape designation.8. Select the upper-left corner of the nested panel, the upper-right corner of the

symbolic panel, and pull the arc away until the radial dimension reads 3-0.


10/11


9. Select the Dimension tool on the Design Bar.10.Dimension the width and thickness of the symbolic panel.11.Select the 3-0 dimension.12.Select the Label pull-down.13.Select Width from the list.14.

Repeat the process by associating the top dimension to the Thickness parameter.15.Save the family. Load it into a test project and test it.

You need to create Types of the door family for each style of door panel. But firstyou need to create visibility parameters to control which panel style is visible.

1. Select one of the nested panels.2. Right-click and select Element Properties.3. Select the small button to the right of the Visibility parameter.4. Click the Add button in the Associate Family Parameter dialog box and name it

for that panel style. I happened to group mine under Graphics.


11/11


In the Family Types dialog, you can set the values of the door family and create a

specific type by clicking the New button under Family Types. Create as many uniquedoor sizes as possible for each panel style. Be sure to check the visibility box next to the

panel style fore each type created. Click the Apply button to establish the type.

Create more panel families and nest them to the Host. Associate the nestedparameters to the host parameters. What you have is a simplified standard library of doortypes.

Below I have loaded the host family into a test project. I add three doors from the

same family. The door family has three types called Flush Panel 36 x 84, Raised

Panel 36 x 84, and Vision Panel 36 x 84.
