Family types not changing in Revit

[ReneBogersREBO]

Hi all,

I have build a "Pipe Fitting" family.

- Family has one type (I called it "TYPE CATALOG")

- The different sizes needed the family extracts from a LookUp Table.

- The family comes with an Type Catalog

When load in project eveything goes wel, I can select a certain instance and change the type to another size.

BUT

When I have for example a 50mm pipe, with the corresponding 50mm fitting and I  change to pipe to 75mm, then the fitting doesn't change to other Type, to match the 75mm.

The fitting stays 50mm and stays connected to the pipe, I can change the type op the fitting manualy, but I want the Type change automaticly with the size change.

Guess I have something wrong / forgot to so something with the parameter added to the connector in the family.

A value from a lookup table will not change from one family type to a different family type.

A value from a lookup table can be used to change parameters (e.g diameters) within the family type.

In your case if you want to change the pipe from 50 to 75 mm then you would use the lookup to change the parameters of that fitting (i.e. family type) so that it resizes to 75 mm.

Or as you indicated (manually)change the fitting from one type to the other

So it's not possible what I want?

First I built the family only with lookuptable and WITHOUT Type Catalog (I had one type, which changes by size change/lookuptable), but I rebuild it with a Type Catalog.

This because I wanted to add parameter values for the different pipe sizes. Those values don't only consist of numbers, but also more than 1 parameter consists text, so it can't be done with Lookuptable.

There is no way to let the familytype change to match the changing pipe size?

Otherwise I have to go back to ONLY the lookuptable and fill the parameters with Dynamo, but if it can be done without Dynamo, then that has my preference, cause Dynamo can't run automaticly on startup in background. Revit user has to start Dynamo itself, and that is not what I want. I want to have the correct info in the parameters automaticly, so without the need of the revit user to do certain things for it to accomplish that.

If you want it fully automatic you could possibly write your own add-in. Add ins can be activated by triggers and therefore able to execute when certain things changes

Would you mind if I send you an email (adres from your website) in Dutch to explain what I want/am doing, to get your point of view about it... I want to make the best descision about how starting up my families to prevent I need do lot of changes lateron.

Or a PM... I see now thats also possible here 😉

Hello,

You can extract one text value from the lookup tables until Revit 2019, I heard, but never tested, that in 2019 it works OK.

Use the formula:

Text Parameter = size_lookup(Size Table, "", "NE", ND)

Yes I know that, I also used that workaround, but I don't need only ONE text value, I need 3 different text values.

The option you mention only works with one value. I need 2 or more, then your solution wont work.

Thnx anyway!

Hello,

You can use multiple lookup tables.

One for each text parameter.

Really?!?!?! That opens other opportunities!!!

So you got me a new option to try out 😉

What I did now is:

- Building 1 family;

- Containing 1 Type;

- Sizes come from Lookups;

- Extra text info comes from Lookups (each value its own lookup).

So I had:

- one .rfa;

- one .txt (Type Catalog);

- one .cvs (Lookup)

Now I have:

- one .rfa;

- couple .cvs (Lookup)
