Exchange an Family

[Anonymous]

Is it possible to exchange an Family by another Family ?

I have in my model a pipe with a valve from Honeywell, and I would like to replace it with one from Oventrop

First family - Honeywell with type TB10

Second family -  Oventrop  with type OT15

Are you just trying to replace an instance of a family that's been placed? If so you can select the instance and set its Symbol property equal to the Family Type you want to switch it to.

an instance

Have you tried match properties?

I take it from your posting history this is an API question rather than UI?

I'm no expert on MEP categories but the usual generic way you change one ElementType for another is by:

Element.ChangeTypeId

Generally if you change an ElementType from what it currently is to one from another family of the same category so be it.

You should review if there are any utility methods within Plumbing namespace to see if there is anything better than the above (to maintain other relationships that may be affected by such a change which I'm not aware of).

sorry my fault 🙄, no the family is already modeled in the model, but because of the price or the customer's choice we have to change brands
so it's not an instance

Keep the family but change the manufacturer parameter so that it appears correct in schedules.

yes, but the dimensions of the valve are not the same

[RPTHOMAS108]

Are you encountering problems with .ChangeTypeId (Families contain types not instances).

Instance based dimensions should remain the same type based ones will change to what is relevant for the type.

May I be the accepted solution...I put in more work than RPTHOMAS108 .
