Transfer unique view templates in Revit

Transferring particular view templates from one Revit project to another can be troublesome from time to time. Put for example, when you tunned the last CD drawings set and you want to transfer an updated version of the modified view templates to another project. Duplicated view templates will add numerical prefixes and they have to be replaced manually.

All this without considering the possible changes that can happen afterward. The average case scenario is the one that view templates are updated more than once in the project lifecycle. Consequentially, new ones will be transferred and renamed while the outdated ones will have to be deleted.

The following script will avoid these headaches. This script is designed to import a specific view template from another project and to override the view template that has the same name in the host project. This means all the views will be updated with the new version of the view template.

# -*- coding: utf-8 -*-
"""Import View Templates.

NOTE: No schedule view template will be transferred. Same name view templates will be overriden and views will be updated.

A few comments about the code:

The script doesn’t deal with schedule view templates, as every schedule view is collected by the class ViewSchedule. This is an idea that can be developed easily and suggestions can be found at the end of this post.

Lines 1-22: usual boilerplate code. Something worth to highlight is line 18, where instead of importing Win Forms, we imported a module in pyRevit that allows us to use forms without creating them from .NET ourselves.

Lines 24-97: all auxiliary code and operations that make the program work:

  • Retrieves all opened documents except the active one.
  • Call form to allow the user to select desired projects.
  • Retrieve all view templates from the previous documents.
  • Call form to allow the user to select desired view templates.
  • Retrieve all view templates from the current document.
  • Check for view templates that have the same name as in the projects to import.
  • Function to collect all views with view templates.

Lines 99-145: the main function to transfer view templates. Basically, it splits the view templates between the ones with the same name as a view template in the project and those that aren’t present in the host project. In the latest case, it directly imports them. In the first case, it will delete the view template first, import the external view template and apply this one to all the views that were assigned with the old view template.

As output, it stores a list of views that have been successfully updated.

Lines 147-158: Display to the user which views have been successfully updated with the new view templates.

This is the script, in a nutshell, it works and it is quite easy to implement, saving us from big headaches like having to delete more than 30 alien view templates imported throughout several different projects.

An option to retrieve and import schedule view templates is to collect all schedule views and check if they are view templates. After that, we can add a for loop to check for schedule view templates inside the retrieveVT. It will be a fun exercise!
