Can I Use a Family template file from 2017 with 2020 version?

[Anonymous]

I am testing the creation of Revit families via C # code and I wonder if it is possible to use a 2017 version family template (.rft file) in a code that will run in later versions of Revit, in 2017, 2018, 2019 and 2020 versions or is Do you need to load a template corresponding to each version of Revit?

The same DLL, same compilation and version, is used in all Revit versions, one dll version per Revit client version is not used.

The templates used are generic and based on a wall.

The template is loaded by the code as a basis for the creation of a new family that will be inserted into a Revit project through the same code, Revit add in.

Is it really necessary to use the templates installed with each version of Revit, even using the same code in C # in all versions?

as long the template file version is same revit version or earlier, then it should be fine. as Revit will upgrade that file the moment you load it. but it is always preferable to have the template file related to revit version, to save the time of upgrading, especially if you are creating many instances.

think of it how much it would cost adding the template files of each version embed in your code against the time of upgrading.

I hope this answers your question.
