RTC 2013 EUR – Boost Your BIM's Harry Mattison Granted Revit API Wishes (Updated)

Updated on December 4, 2016: changed sort order to descending.

From the Boost Your BIM website:

#RTCEUR Wish #1 – Push parameter from Host to Hosted

@Jbenoit44 suggested a tool to push a param from any Host (including levels and reference planes) to any Hosted & reverse. Doors. windows, face based family, Parts, etc

This implementation drives parameters from Hosts to their Family Instances.

#RTCEUR Wish 2 – Highlight and Isolate Warning Elements

@marcellosgamb suggested an API that runs thru every error in a model, turns element w/error red, then, as you fix each error, turns normal.

There is no API access to the Revit “Review Warnings” data, so this implementation requires the user to export the warning data. The program then imports this HTML, parses it to find the element IDs, and then isolates and colors the elements in two 3D views.

#RTCEUR Wish 3 – Copy View Types & Templates btw Documents

Q: Would be possible to create a tool that would “Transfer View Types” from one project to another?

Background: View Types have a couple of key properties, an assigned View Template, and if new view instances created from the Type should be dependent on the View Template. But the Revit UI does not allow view types to be transferred between projects.

A: Good news! With the API it is possible to determine the View Types defined in a project, read their associated parameters, create new View Types in a second Project, and set these parameters to match the values in the source project.

#RTCEUR Wish 4 – Find Native and RVT Link Penetrating Elements

This sample shows how the BoundingBoxIntersectsFilter can be used to find elements that penetrate ceilings in the model.

The host file contains 2 ceilings, 2 columns, and a RVT link that contains 3 Generic Model elements. There are also 3 shaft openings in the ceiling so that there is no interference between the ceilings and the elements going through them.

This API code analyzes the bounding box of each ceiling and finds all elements in all files (including the current RVT and links) whose bounding box intersects the ceiling’s bounding box. The results are shown in a dialog and written to a parameter of the ceiling category.

#RTCEUR Wish 5 – Who Created Those Warnings?

To help BIM Managers train or punish their Revit users, I was asked at RTC in Delft if we can use the API to figure out which users are responsible for each warning in your Revit file.

Here’s how that can be done by writing all warnings to a log file and then comparing warnings in the current file with those in the log.
