Roomedit3d Viewer Extension, POST and Socket

I returned from the Barcelona Forge Accelerator, where I started an exciting new project connecting BIM and the cloud demonstrating two cool possibilities to enhance interaction with the View and Data API, a viewer extension enabling interactive model modification, i.e., translation of selected elements, and a real-time communication of the modification back to the source CAD system – It's Read-Only! How can it be Read-Write? – Genealogy or Where to Start? – Capturing the TransformTool Selection – Determining the TransformTool Translation Vector – POST From Viewer to Server – Broadcast via Socket.io – Desktop Notification Connection and Subscription – Demo Recording – Download and Diff – To Do...

FireRatingCloud Query Retrieving Updated Docs

Yesterday, I added a timestamp to my FireRatingCloud mongodb documents with the intention of retrieving only documents modified after a specific moment. Today, let's look at filtering for and retrieving just those. Here are the steps to achieve that – A MongoDB query and express route using $gt – C# REST API client accessing the new route – Download and diff... Read more →

FireRatingCloud Doc Modification Timestamp

The last task I discussed here was the FireRatingCloud batch upload functionality. FireRatingCloud is a C# .NET Revit API add-in REST API MongoDB client of the fireratingdb node.js MongoDB web server. The details of the research and development for this project is extensively documented in the FireRatingCloud GitHub repository. The batch upload vastly improves the upload speed, since an upload of N records is reduced from N separate REST API calls to a constant 2... Read more →

FireRatingCloud REST API Batch Upload and Windows Client

Before getting technical, let me mention that I had a great time with Markus and Wolfgang on ski tours climbing a couple of mountains around the Gemmipass last weekend. Back to the technical stuff, I implemented a batch upload functionality for the FireRatingCloud C# .NET Revit API add-in REST API MongoDB client over a month ago, in Madrid, during the BIM Programming workshop, together with Jose Ignacio Montes of Avatar BIM. Jose noted that uploading the data for all doors in a large building model to the cloud database consumed a significant amount of time, whereas downloading the modified data for the same doors is almost instantaneous...

Viewing a Space and Exciting Times Ahead

Today, let's recapitulate a discussion on viewing architectural spaces in the View and Data API, plus take a look at all the exciting things happening both for myself in the next weeks and for Autodesk as a company as a whole, reinventing itself for the modern cloud-based collaborative sharing technoculture – The first annual Autodesk X summit – Jeremy's January – DevDay in Munich – Accelerator Workshop – BIM Workshop in Madrid – Viewing IFC spaces and models...

RTC Report LMV Model Upload and Translation

I presented the CompHound component tracker project as work in progress at the Revit Technology Conference RTC Europe in Budapest last week – RTC Conference and Connecting Desktop and Cloud – Driving the View and Data API Upload and Translation from a C# Add-In – Current CompHound Versions and To Do – Meanwhile, autumn is well advanced here in Switzerland...

Lunar Eclipse, CORS Workaround, CompHound

This weekend, I wanted to add an additional field to the component occurrences in the CompHoundWeb database, which led me to discover and fix a trivial yet serious error in my C# client. Also, let me mention a CORS workaround pointed out by my colleague Cyrille Fauvel and my night out to watch the lunar eclipse: – Lunar eclipse – Fed up with CORS? – CompHound Updates... Read more →

C# DoorData and Node.js DoorService Classes

I continued improving my REST API node.js web server, mongo database and C# REST API client, and also set up a Google domain rerouting – CompHound domain, organisation web site and rerouting – Implementing a DoorData container class – Updating Get to return a list of deserialised DoorData instances – Passing a DoorData instance to the Put method – Implementing a REST API router DoorService class...

CompHound, RestSharp, Mongo PUT and POST

I spent a few exciting and satisfying hours last night cleaning up my C# REST API client to use RestSharp instead of HttpWebRequest and the node.js mongo web server to enable PUT to create as well as update a record – Use percent for CSS font-size font sizing – The CompHound component tracker – GET, PUT and POST stupidity creating versus updating a record – Enabling PUT to create as well as update – Using RestSharp instead of HttpWebRequest – No need to format data as JSON...

FireRatingCloud Heroku + Mongolab Deployed

Fully and completely deploying the FireRatingCloud support database on the cloud was much easier than expected. Please refer to the fireratingdb node.js web server and FireRatingCloud Revit add-in GitHub repositories for an overview of the exploration and project evolution. I already moved the database off-site to the mongolab host yesterday, but I still had the node web server running locally. To do so, I created a new Heroku app and linked it to the existing fireratingdb GitHub repo. I asked... Read more →

FireRatingCloud Round Trip and on Mongolab

I completed the initial FireRating conversion to the cloud. Here are the steps it took to reach that point: Revit project identification Complete Revit Add-in Implementation Demo Run Log Demo Video Mongolab – really in the cloud Postman does more than cURL Wrap-up, Download and Outlook It now runs full circle, storing Revit building model door instance fire rating values for multiple projects in a cloud-based mongo database. It implements the same three commands as the original FireRating SDK sample... Read more →

C# .NET REST API GET and PUT MongoDB Storage

Yesterday, I set up MongoDB and the fireratingdb node.js web server driving it on Windows and started populating the database from a desktop C# .NET add-in via its REST API. Today, let's complete that, adding the door instance documents to the project data: Adding a JSON parser module Storing door instance documents in mongo Using PUT instead of POST when the database id is known Checking for project existence before adding new Adding a JSON parser module Once a project...

Implementing Mongo Database Relationships

Let's look at how to implement relationships in a mongo database. Yesterday, I made my very first steps exploring mongoDB to implement a mongoose based node.js database web server. The example I am using is a hopefully simple project to implement a cloud-based multi-project version of the Revit SDK FireRating sample. The relationships we are dealing with here are as trivial as they get: we are looking at doors in a building, represented by door family instances in a Revit... Read more →

Driving the SVG Node Server from a Desktop Application

Yesterday, I implemented a pretty minimal Heroku-hosted node.js web server and used it to display some SVG graphics. I implemented a little interactive form and used the following JavaScript snippet to invoke the server and submit the data entered to it: function submit_form_svg_01(path_data) { var local = false; var base_url = local ? 'http://127.0.0.1:5000' : 'https://shielded-hamlet-1585.herokuapp.com'; var w = 400; var h = 400; var d = path_data.replace(' ','+'); var query_string = 'w='+w+'&h='+h+'&d='+d; window.open(base_url + '?' + query_string, 'node_server', 'width='...
