Molding#

Design Revit families (.rfa) in a visual node graph with a live 3D preview — instead of drawing them by hand in Revit's Family Editor.

Building a parametric family in Revit normally means sketching each form, placing reference planes, dimensioning them, and labelling every dimension to a parameter — by hand, one click at a time. Molding replaces that with a node graph: you wire Shape nodes into Form nodes, declare a few parameters, and watch the family update live in 3D.

When you are happy, Molding generates the .rfa for you — complete with the reference planes, dimensions, and parameter associations that make it parametric. From then on it is an ordinary Revit family: Revit's own solver recomputes the geometry when you change a value. No Molding plugin is needed at runtime.

Why a node graph#

• A family is a small, readable definition — easy for you to edit, and easy for AI to generate or tweak.
• The 3D preview updates as you type, so you see the result before ever opening Revit.
• The Family Editor's clutter (dense reference planes and dimensions) is generated for you and never has to be read by a human.
