We tested it in a lot of scenarios, small and large files, and it always worked as expected. It really worked great and much faster than our previous attempts! Later: some feedback on the integration of the Purge Code from the Dynamo for Revit code base: That looks very relevant, as it includes a method to purge materials. Response: Thank you very much for the quick response. Not sure how closely that follows the ETransmit code, or if it’s a viable option, but it's worth a review all the same. Question: We are trying to implement the eTransmit functionality in DA4R, the Forge Design Automation API for Revit.Īnswer: This might be another good instance of learning from the Dynamo for Revit code base, as there is The Forge Design Automation for Revit API, DA4R, The task of purging a step further and implemented it for

Many thanks again to Matt and Ollie for providing this. There's also an IronPython version of more or less the same in

I had a quick go at putting this together in C#. Thanks to Matt for sharing and to Jeremy for spreading the knowledge! Ollie ported it to both C# and Python, saying: Matt Taylor, associate and CAD developer at WSP, provided the original implementation in VB.NET. Thank you for the code and thanks to Ollie for publishing it in C#. WOAW this post is awesome, and it seems to work in Revit 2021 very well! You can purge unused using Performance Adviser,Īs Virone Lorenzo also underlined in his comment: Here are some past suggestions for purging unused elements:Īpparently, the last post in the list above is worthwhile pointing out again I want to write a script to purge unused in files.Īnswer: All I am aware of is what you can find in the online help and in the web in general: Question: Is there documentation for eTransmit? Lately, a number of questions were raised on eTransmit and 'purge unused', e.g., in Today, let's return for a summary and a new, deeper look at a recurring topic:
