Ready to release!

When the npm run build command is run, the output is a static website. This means that all of the files and assets that are needed to serve your site to your users are bundled under the same parent directory, and all that you need to do is get that…

The iTwin viewer is the starting point for any iTwin web application. It comes with important navigation tools, widgets, and a viewport to render the graphics of your digital twin. But how do we take it beyond this basic setup? Let’s answer that commonly asked question below.

In the following webinar — we start out with a freshly cloned copy of the viewer and do a quick code walk-through. Next, we enhance it with some UI widgets — first with a basic run-of-the-mill “hello world” widget, followed by a more complex one imported from the sample showcase. …

iTwin.js is not just an excellent library for web, desktop, and mobile applications — it’s also an effective foundation for virtual and augmented reality.

I recently recorded a webinar showing how to integrate your iTwin-based digital twin with the Unity game engine. Unity is one of the leading platforms for AR/VR, and by following the instructions in this webinar, you can be streaming your digital twin into your headset in just a few hours.

Please give it a try and let us know what you think on the iTwin.js GitHub discussion forum: https://github.com/imodeljs/imodeljs/discussions

Hey everyone, it’s been a minute! We haven’t forgotten about you — things have, been, uh, a little crazy. How are you holding up these past two months? #2020needstoend

Good news though, we are back and super excited to tell you about our inaugural iTwin Developer Conference on November 4 and 5. Remember the JumpStart event from August? Well, DevCon is the next event the team has organized. We’ll be taking things to the next level.

Since we still can’t hangout IRL, let’s hangout virtually. We’ve brought in the best and the brightest to talk…

TowerSight is a TypeScript/React web application that is built using iModel.js framework. It is a part of bigger solution called OpenTower that serves as a transformation tool for design practices of telecom towers. OpenTower is a fully integrated solution that transforms the design practices of telecom towers by encompassing the entire lifecycle management of tower engineering. From tower analysis to inspection and reality models, TowerSight, as part of OpenTower solution, completes the loop using a tower digital twin, making it easy to modify existing towers and maintain accurate models.

First Impression

So you want to use React with iModel.js? Great, React is a very popular web framework for very good reasons, it has a huge following, a huge community and tons of open source packages to build upon. How to deal with classes in React will be important to us in an iModel.js app, since iModel.js is chock-full of framework-agnostic vanilla TypeScript classes. In a previous article, Writing a Primitive Tool, I built a microscopic iModel.js app, which I will improve here by applying the Provider-Local Class pattern.

This is my favorite pattern for using vanilla JavaScript classes in React.

We'll…

This tutorial, while self-contained, also serves as context to the article, The Provider-Local Class Pattern. If you’re an experienced programmer, I’d suggest checking out that article after for some discussion on scaling iModel.js applications.

Together in this article we’ll build a primitive iModel.js app with a PrimitiveTool.

I call it: The Pin Tool

We’ll load an iModel, and have our tool place a ‘pin’ in the viewport where the user chooses. All of the added pins will be listed in a sidebar, and the user can “manage” their pins. We’ll fork a starting point from the iModel.js basic viewport app sample to make things quick. Each…

The What

It can be extended with additional functionality via iModel.js Extensions.

The Why

The iTwin Viewer simplifies the process of adding an iModel.js viewer to a new or existing application and decreases the amount of time that would be required to get “up and running”…

So, here’s a quick one. This is by no means a full-blown guide on how to add Revit files to an iModel, this is simply a quick and dirty overview, guiding you through the sequence you’ll need to follow.

Some might know the famous Revit sample house. In my previous life, I often used this project to demonstrate Revit features during team training. Geolocating projects in Revit isn’t the easiest and there are multiple ways to achieve this. Almost everyone has a slightly different approach to this.

In case you have Revit available here’s where you can find the sample…
