Can you create a Revit ʼFamilyʼ from scratch?
Short Answer
Yes — you can create a revit family from scratch using Autodesk Revit’s standard family editor workflow. The most common professional method is to start from the correct family template, build reference planes and parametric geometry, then load the family into a project. Limitation: some system families cannot be created this way.
What You Need to Know Before
Warning: Choosing the wrong family template at the start is one of the most common failures, because category, hosting behavior, and built-in parameters cannot be changed later in most cases. Poorly constrained reference planes can also cause the family to break when dimensions change.
How-to
Command: Family Editor
Shortcut: No default keyboard shortcut
Quick Steps:
- In Revit, go to Ribbon > File > New > Family, then select the correct family template such as Door, Furniture, or Generic Model.
- In the Create tab inside Family Editor, add Reference Planes, dimensions, and set key dimensions as Label parameters to make the family parametric.
- Create geometry with tools like Extrusion or Blend, then use Load into Project on the Ribbon and test the family with different parameter values.
Variables & Settings
Key Setting: Family Category and Parameters
Expert Setting: This controls the family category, host type, cut behavior, and whether options like Shared or Work Plane-Based are enabled. If this is set incorrectly, the family may schedule improperly, fail to host correctly, or behave incorrectly in projects.
Why it Fails
- Cause 1 (Geometry): Sketches are not fully closed or solid geometry is not properly locked to reference planes, so the family fails when parameters flex.
- Cause 2 (layers/Locks): Dimensions and geometry are locked to the wrong references, or imported CAD linework is used as a modeling basis and creates unstable constraints.
- Cause 3 (Command/Logic): The wrong family template was used, so required behavior like wall-hosting, face-hosting, or annotation scaling is unavailable.
Quick Fix & Best Practice
- Quick Fix: Open Family Category and Parameters, confirm the correct category and hosting, then rebuild geometry using locked reference planes and labeled dimensions before reloading into the project.
- Manager’s Verdict: Create a Revit Family from scratch when you need clean, reusable, parametric content. Avoid it for objects that already exist in vetted manufacturer libraries unless customization or standards control is required.
FAQ
Can you make a parametric Revit Family from scratch?
Yes, by using reference planes, labeled dimensions, and family parameters.
Can all Revit families be created from scratch in Family Editor?
No, system families like walls, floors, and roofs are not created as standalone family files.
Should you import dwg to build a Revit Family?
Only as a tracing reference if necessary, because direct dependence on imported CAD often causes unstable families.
