Does anyone know how to create Revit family types for and from a .dwg file?

We want the component to have multiple sizes. We watched videos of people creating their families from scratch and adding family types to it. However, we imported our component from AutoCad, and we tried adding family types to it, but it doesn't work.

Are you wanting to import the CAD into a Revit Family Template to use as a temporary guide, or are you saying you actually want to permanently incorporate the CAD into the Revit Family?

You can create families , different types if its done in CAD..

Example table size A, B, C

in Table family, on plan, import / insert various cad for various size. and using

visibility you may create different types ..

The DWG file is only going to give you the raw geometry not somehow automatically allow types to be created.  It sounds like maybe you have a dynamic block in DWG and are expecting family types to automatically be created from a dynamic block?  That is not going to happen.

 

The DWG could be used a a basis for the geometry of the family, then you need to create dimensions/constraints in Revit to make it possible to move that geometry. Once you have the dimensions there you have to "label" the dimension which means you are associating the dimensional value to a parameter value. Once labeled, you can change the parameter value and the dimension will change, thus moving the constrained element. NOW you are ready for types. You can create different types which are kind of like "preset" parameter values.

 

That is a really short "Reader's Digest" version of family authoring. This is how you get types that change the size of your geometry. Just having the DWG is only the beginning, and in all honesty should probably just be abandoned completely. Print it out, keep it by your computer for reference as you author the family from scratch in Revit.

Permanently incorporate the CAD file into the family template, and add family types to it.

Your transitioning from AutoCAD, aren't you? All I can't say is don't do what you're thinking. You'll regret it.  Just bite the bullet and build  Revit Families with Revit elements.  Don't mix CAD content with BIM content. Sure, you can import the CAD into the Revit Family to use as a reference to recreate it with Revit elements - but don't make it a permanent resident in the Family.
