Good day, all-
Hopefully the subject says it all. I have a family that has over thirty types and I need to update a single parameter value across all types to be the same value. Is there a global way anyone knows to perform this task instead of the current copy/paste/paste/paste method I am doing. I thought about exporting to a catalog and modifying the text file in Excel, but I lose my formulae when I do that.
Any help would be appreciated.
If this isn't possible, this would be a good wishlist item, Autodesk - where a family has global parameters that are consistent throughout the family, regardless of type.
Solved! Go to Solution.
First of all you need to understand the essentials of creating a family which has multiple type:
You have created the family in a wrong way if it has over thirty types.
It is a know fact that any family which has more than 6 types should be created using TYPE CATALOG .
In case you don't know, type catalog is a simple text (.txt) file with very simple syntax to write.
You need to put the type catalog file in the same folder where you family is saved.
If you want to change the value of one particular parameter, you can easily do that in a type catalog text file.
Let me know if want to know more about 'how to create type catalog'.
Thanks Alfredo and Parveen-
Placing the value in the formula column worked in the fashion I was looking. In the end, I will use a combination of both suggestions - I just still needed to maintain the formula relationships inside of Revit at this time. The catalog was always the intent.
While I agree that having a large number of types within one family can become cumbersome, I wouldn't go so far as to set a limit of 6 types before a type catalogue is needed. I have some families with around 10-12 types in them, based on various visibility configurations, that wouldn't necessarily benefit from a type catalogue. Whether or not someone decides to use a type catalog should be a decision made based on the family they're creating, not just the number of types within that family. Just my two cents.
if the number of family type (with simple paramters like length,width and height etc.) is higher, you'll find it difficult to create that number of types within family. It takes more than just typing it in a text document.
my team has created more than 8000 families for different manufactureres and consultant across globe and has developed excellent checklist, some add-in tools for automated quality check and to make sure we follow the standard steps to comply with autodeks seek guideline.
based on their experience they have suggested that 6 is the benchmark number to decide to go for Type Catalog.
For families with simple parameters, yes, a type catalog can be useful.
But if I've got, let's say, a cubicle family, with multiple nested families for various pieces of equipment (desks, filing cabinets, lighting, power, partitions, etc.), all with various location and on/off configurations, then a type catalog is less useful, even if I have more than 6 types.
I just didn't want people to interpret your phrasing in your previous post as implying that there's some kind of hard-limit on the number of types you can have within a family before you need to use a type catalog.
It all depends on the level of comfort. If you could do it with family types within family without spending too much time, its good.
Whatever save you time and hassle, should be your preference.
