ABOUT CLIENT
As the first company to emerge from Google X, HELIXRE is leading the charge to bring ‘digital twinning’ to all. They create accurate digital equivalents of entire buildings at a fraction of the normal time and cost.
Sector
CAD, Cloud, Microservices
Headquarters
U.S.A
THE PROJECT
- IFC to OBJ and metadata
- Revit to OBJ and metadata
- Helix Revit Addin creator
- RCS Converter
Language and SDK: C++, C#, Python, HOOPS Exchange, Teigha BIM, Forge Design Automation for Revit, PDAL, Autodesk Recap
THE CHALLENGE
- Get the model data of the IFC file (tessellation data and metadata/properties) in two different custom files in order to store in the database so that it can be queried faster
- Get the model data of Revit file (tessellation data and metadata/properties) in two different files in database so that it can be queried faster
- Create 3D Revit model from entity data. Complete Revit model cannot be created from input data
- Extract point cloud data (points, color, intensity and normals) and generate point cloud in RCS (Autodesk Reality capture scan) format
THE SOLUTION
- Serialized tessellation data in obj format using 3rd party SDK. Fetched the metadata/properties and serialized it in custom JSON format
- Implemented an OBJ and JSON serializer using Teigha BIM SDK, to export tessellation data in obj format and metadata/properties in custom JSON format. Also exported view data to pdf and svg format
- Deserialized structured data from entity data and created each Revit entity to generate Revit model using Forge Design Automation for Revit API
- Gathered the LAS, LAZ or EPT data (points, color, intensity and normals) and converted it to RCS using Autodesk Recap SDK
We have got a winner here! I personally appreciate the dedication and teamwork of the ProtoTech developers for making the challenges achievable. Good Job Guys!
