I'll create a construction website using Autodesk Platform Services (APS) for 3D model viewing. This will be a Next.js project with a 3D viewer component. Let's start by setting up the basic structure and components.

This setup creates a basic construction website with a 3D viewer using Autodesk Platform Services. Here's a breakdown of what we've done:

1. We've set up a basic Next.js project structure with a layout, header, footer, and main page.
2. The Viewer component integrates the Autodesk Viewer library. It loads the viewer script dynamically and initializes the viewer when the component mounts.
3. The main page (app/page.tsx) brings everything together, displaying the header, the 3D viewer, and the footer.

To make this fully functional, you'll need to do the following:

1. Replace 'YOUR_URN' in the Viewer component with the actual URN of your 3D model. You'll need to upload your model to Autodesk's Model Derivative API to get this URN.
2. Set up authentication with Autodesk Platform Services. This typically involves creating a server-side API route to handle token generation and management.
3. Style the components further to match your desired design.
4. Add more pages and functionality as needed for your construction website.

Remember to handle errors gracefully and provide fallback content in case the 3D viewer fails to load.

Would you like me to explain any part of this setup in more detail or add any specific features to the website?
