Revit Family Creation Guide

Revit Family Construction can be categorized into four types: system families, component families, in-place families, and conceptual massing families. There are different methods for creating furniture families in Revit including: importing and modifying AutoCAD data; using AutoCAD data as a template for Revit elements; creating families from linked AutoCAD files in a Revit project; or building new families from scratch with Revit elements. Key aspects of family creation include setting up the family skeleton with reference lines and planes, family views, parameters, and type names.

Revit Family Construction – General

 Type of Families
o System Families
o Component Families
o In Place Families
o Conceptual Massing Families

 Family Categories at the Project Level

o Sub-Categories

 Family Category and Parameters at the Family Level


o Omni Codes

o Assembly Codes
 Family Skeleton
o Reference Lines
 Have a beginning and an ending point (can be used to rotate elements)
o Reference Planes
 Extend to infinity in all directions

 Family View References


The Good News. The Bad News. (not all families are created equal)

 Symbolic Lines vs Model Lines

Creating Furniture Families - Database and Project Files


 Methods for Family Creation
a. Created by importing, exploding and using AutoCAD data
i. Pre-import modifications to AutoCAD data
ii. Post-import modifications
b. Created by importing AutoCAD data as a template for Revit elements
c. Created from an linked AutoCAD file in a Revit project
d. Build a new family from scratch with Revit elements

AutoCAD data: Modify, Import, Explode and Revise (Method “a”)


 Open AutoCAD furniture and modify insertion point at 0,0,0
 Verify Units are set to Architectural

 Explode to layer 0, set color ByLayer, set LineType by layer. Delete text.

SaveAs:________

 Create new Revit Furniture family (use the FurnitureMayo template)

 Ribbon> Insert tab > Import CAD (LobbySeat_Raw_Import.dwg)


 Select import data and explode

 Ribbon> Annotate> Masking Region (Create a masking region around the perimeter of the element).
 Ribbon> Create tab> Family Types (parameters):
 Create Type name and set the Mayo CAP using our naming standards
 Save family per our naming conventions

AutoCAD data: Import as template for Revit Elements (Method “b”)


 Open AutoCAD furniture and modify insertion point at 0,0,0
 Verify Units are set to Architectural
 Create new Revit Furniture family (use the FurnitureMayo template)

 Ribbon> Insert tab > Import CAD (LobbySeat_Raw.dwg)

 Ribbon> Annotate> Symbolic Lines> (Subcategory: Furniture)


 Use the pick tool to create line-work to denote element. Delete the import data.
 Ribbon> Annotate> Masking Region (create mask)
 Ribbon> Create tab> Family Types (parameters):
 Create Type name and set the Mayo CAP using our naming standards
 Save family per our naming conventions
 Create Revit Family from Linked AutoCAD file in Revit Project (Method “c”)

 Open STCS, navigate view 1ST FLOOR – ARCH


 Ribbon> Architecture> Component> Model in Place (accept the default Category and Name)
 Create new ‘Extrusion’. Use the pick tool to create new family line-work.

Copy line-work to clipboard

 Create new Revit Furniture family (use the FurnitureMayo template)


 Past line-work from clipboard into family and move to insertion point.

 Select line-work and convert to 2d line-work


 Create ‘Mask’ for element

(Note: at this point you could finish the family by adding the Type Name and MayCAP, saving the family and inserting into
the project)

 Move the line-work and mask ¾” to the left of the center. Select the ‘Visible’ (associate family parameter) box
from the properties of the combined line-work and mask. Add the Type parameter ‘Left’.

 Select line-work/mask and mirror about the center reference plane. Select the ‘Visible’ parameter and create
new associate family parameter ‘Right’.
 Ribbon> Create> Family Types
 Create two (2) Type names (Half Table, Full Table) and set the visibility parameters to match the condition.

Name and save family. Note: Cancel the In Place Family in the project prior to inserting new family.
