ThatOpen-Claude-Skill-Package gives you 18 ready-made Claude Code skills for ThatOpen Engine 3.3.x.
It is built for people who work with web-based BIM apps, IFC files, and ThatOpen tools. These skills help Claude handle common tasks with more structure, so you can move through setup, modeling, data work, and app building with less manual work.
- Windows 10 or Windows 11
- A web browser
- Access to the internet
- Enough disk space for the release files
- ThatOpen Engine 3.3.x if you plan to use the skills in a live project
If you plan to work with IFC data or Three.js scenes, a modern PC with at least 8 GB of RAM helps.

Follow these steps on Windows:
- Open the release page in your browser.
- Find the latest release at the top of the page.
- Download the package file from that release.
- If the file comes as a ZIP file, right-click it and choose Extract All.
- Open the extracted folder.
- Copy the skill files into the place where Claude Code reads skills on your machine or project.
- Restart Claude Code if it is already open.
- Test one skill in a simple task to confirm it loads.
If the release includes a setup file, download and run this file.
After you install the package, use one small task first.
A good first test is to ask Claude to help with a simple BIM task, such as:
- reading an IFC file
- checking model data
- preparing a web app task list
- setting up a ThatOpen workflow
- explaining a Three.js scene step by step
This helps you confirm the skills are in place and working as expected.
This package includes 18 Claude Code skills for common ThatOpen Engine work.
Typical skill coverage includes:
- IFC file handling
- model data checks
- web BIM app structure
- app setup steps
- scene and object flow
- project organization
- deterministic task steps
- ThatOpen Engine 3.3.x support
- Three.js related workflows
- OpenAEC-style data work
- repeatable coding tasks
- help with agent-driven work
- clean handoff between tasks
- practical project guidance
- file and folder planning
- UI and app logic support
- documentation-focused help
- build-ready workflow steps
These skills are meant to keep Claude on track when you work on BIM tools for the web.
Use the skills when you want Claude to work in a more structured way.
Try prompts like:
- Help me inspect this IFC file for missing data.
- Build a simple ThatOpen web app flow for model loading.
- Organize the steps for a BIM viewer in Three.js.
- Give me a deterministic plan for this task.
- Help me prepare a clean project structure for ThatOpen Engine 3.3.x.
Keep your requests short and clear. Claude works best when you tell it the goal, the file, and the result you want.
A simple workflow looks like this:
- Open your project in Claude Code.
- Make sure the skill package is installed.
- Choose the task you want to do.
- Ask Claude for one step at a time.
- Review the result before moving on.
- Repeat for the next task.
This works well for BIM apps because each step depends on the last one. A clear order helps avoid mistakes.
Place the skill files where Claude Code expects skills for your setup.
If you use a project-level setup, keep the files inside the project folder.
If you use a shared setup, keep the files in your global Claude Code skills folder.
Use one consistent location so you can find and update the skills later.
This package fits well if you work on:
- web-based BIM viewers
- IFC inspection tools
- model data dashboards
- ThatOpen Engine apps
- Three.js scene setups
- OpenAEC workflows
- repeatable AI-assisted coding tasks
It also helps when you want Claude to follow the same process each time instead of changing its approach from task to task.
Some tasks need the same result every time. That is where deterministic skills help.
Use them when you want:
- the same step order
- fewer changes in output
- clear task flow
- stable project actions
- less guesswork
This is useful for team work, where other people need to follow the same process later.
- Check that you placed the files in the right folder.
- Make sure the files are extracted if they came in a ZIP file.
- Restart Claude Code.
- Try a simple prompt again.
- Use a clear task request.
- Make sure the skill name is loaded in the right place.
- Check that you are using the latest release.
- Try a task tied to BIM, IFC, or ThatOpen Engine.
- Refresh the page.
- Scroll to the latest release.
- Look for assets or attached files under the release name.
