Copying parameters in Revit within a single parameter is a time-consuming task. Thanks to the function of copying parameters in my overlay PYLAB you will be able to easily rewrite the value of any parameters for all elements of the selected category.
In “Revit copy parameters” post:
The program for copying parameters for many elements is designed to speed up the process of parameterization of the Revit model. Thanks to this, there is no need to rewrite the values manually. When can you use it?
Instruction how to install my extension you can find here.
First, the program asks us to indicate the element. Relative to its category, the program will select all elements in the model.
Then the program will ask us to select the parameter to be copied. The list is arranged alphabetically. Thanks to this, it is possible to quickly find the variable we are interested in.
In the last step, the program filters the parameters to which we can rewrite the selected value. If we create our own parameter of the same type as the copied variant, we will find it in this list.
After the last selection, the program will rewrite the values in all elements. At the end of the process, we will receive a list of elements that have been rewritten / or not. We will also learn about errors.
Below is the program code from the first version of the overlay. For more please visit mine GitHub, where new versions of the overlay will appear on a regular basis.
