Batch Processing and Aspects of AsStringValue

I avoid answering non-confidential questions in private, as I tell everyone who tries to do so. However, some non-confidential queries still come in via ADN. Here are two that came in today that might be of general interest and therefore seem worth sharing – Batch processing Revit families and documents – AsString and AsValueString results differ...

Before Getting Started with Design Automation

Several people have recently asked how to get started with Forge Design Automation for Revit or DA4R. I will not get into any nitty-gritty details, since they are well covered by the Forge Design Automation API documentation, which includes DA4R tutorials and samples. Here are examples of two conversations on planning first steps for DA4R solutions – Structural analysis with DA4R – Implementing a DA4R RVT round trip... Read more →

External Access to the Revit API

We are currently being flooded with questions about a topic that has already been discussed repeatedly and in depth in the past, external access to the Revit API. Possibly, the cause is the growing interest in implementing web driven solutions to generate RFA and RVT files. It is in fact possible to implement a web server driving Revit in the background to execute such tasks, as demonstrated by the old sample showing how to drive Revit through a WCF service and other examples listed in the topic group on Idling and external events for modeless access and driving Revit from outside – Revit I/O and Forge – Question – Answer...

Retrieving and Broadcasting the Roomedit3dv3 Translation

As I discussed last week, the translation tool emits info about its activity via socket.io. Now I want to pick up that information higher up, in the viewer transform extension, and relay it to the node.js web server or broadcast it to the rest of the world. The existing sample call to emit is inside onTxChange, which is called on each mouse move. We do not need to track each mouse movement in such fine detail... Read more →

Solid From Bounding Box and Forge Webinar 4

I submitted the handout for my presentation on connecting the desktop and cloud for the RTC Revit Technology Conference Europe in Porto next month. I still have to finish my work on the roomedit3dv3 sample to demonstrate connecting the desktop with the cloud by enabling a real-time round-trip modification of the BIM via the Forge viewer; yesterday I integrated the transform viewer extension; now I have to hook up the socket.io messaging back to the Revit add-in to update the BIM – Create solid from bounding box – Forge webinar series 4 – Viewer...

Flipping a Section View and Forge Webinar 3

I already created a starting point for the new roomedit3d incarnation last week, in its own repository. This week, I agreed with Philippe to retain the new project in an own branch within the Forge boilerplate code sample collection. Hopefully, that will simplify keeping my BIM sample synchronised with any future updates make to that. Now I need to get started implementing and testing the actual viewer extension functionality itself. My main topic today is something different and purely Revit API oriented, besides the next Forge session – Flipping a section view – Forge webinar series... Read more →

Exporting RVT BIM to JSON, WebGL and Forge

I am happy to say that I returned safe and sound to Switzerland from my travels for the Forge DevCon and Cloud Accelerator. Since then, I rounded off the hierarchical MEP system exporter to a JSON graph for interaction with it in the Forge viewer, worked on an update of the ADN JSON mesh exporter and helped my son Christopher getting started with C# scripting to drive audio effects for professional spatialized sound design for computer games – More TraverseAllSystems updates – CustomExporterAdnMeshJson updates – ADN JSON Exporter Alternatives to View RVT in WebGL – vA3C – The Forge Viewer – Getting started with Unity C# scripting – Opendesk at Autodesk Forge Accelerator Barcelona...

Thank you for your questions during the Autodesk answer day. I am still busy supporting the Barcelona Forge Accelerator participants in the Autodesk office. I am also working on a very exciting new project connecting BIM and the cloud using a direct socket.io connection to communicate changes back to the desktop, instead of the inefficient polling mechanism I implemented in previous projects. Once again, it consists of two parts, the node.js web server and View and Data API handler and the C# .NET Revit API add-in client – Revit Idea Station – TextNote Bounding Box Requires Regen – Regeneration Performance Benchmark...
