From SketchUp to IDA ICE in Minutes: The Fast-Track BPS Workflow

SketchUp remains a highly favored conceptual design tool for simulation engineers due to its agility in mocking up early-stage building volumes. However, because it is natively optimized for raw geometric visualization rather than rigid structural BIM data classification, standard IFC exports from SketchUp frequently result in messy, un-normalized spatial schemas.

When forced directly into rigid building performance simulation (BPS) environments like IDA ICE, these files trigger fatal spatial boundary conflicts and geometry errors.

To overcome this, engineers are left with two choices: waste days completely rebuilding the architectural envelope by hand, or implement a rapid, plugin-driven model-repair sequence.

Technical Step-by-Step: The SketchUp-to-abstractBIM Optimization Protocol

This advanced workflow uses SketchUp as a lightning-fast model-triage workspace combined with an open-source IFC manager, using abstractBIM to handle final downstream compilation for IDA ICE.

1. Import the Raw Architectural IFC Data (Phase 1): Instead of starting from a blank canvas, import the architect's unstandardized IFC file straight into SketchUp. To bridge the data gap, install the open-source extension SketchUp IFC Manager by BIM-Tools to manage the spatial tree and classification attributes directly inside your viewport.
2. Audit and Inject Missing Spaces (Phase 2): Simulation software relies entirely on airtight volumes. Review the model tree inside the IFC Manager extension. If the architect forgot to map rooms or left out critical structural zones, quickly sketch simple 3D bounding shapes and classify them as explicit space attributes (IfcSpaces).
3. Simplify Complex Spatial Geometry (Phase 3): Multi-sided polygons, curved architectural elements, and intricate geometric extensions cause calculation engines to stall or crash. Use SketchUp's push-pull agility to radically simplify complex room volumes into clean, orthogonal boxes.
4. Export via the IFC Manager Plugin (Phase 4): Do not use SketchUp's native file exporter. Instead, run the export command directly through the BIM-Tools IFC Manager plugin. This ensures the explicit property dictionaries, localized spatial hierarchies, and customized GUID structures remain intact and uncorrupted.
5. Translate and Normalize with abstractBIM (Phase 5): Upload your streamlined SketchUp IFC file to abstractbim.com. The automation cloud engine takes over, executing precise algorithmic normalization—closing micro-gaps, identifying adjoining spatial intersections, and correcting remaining geometric defects.
6. Execute Seamless Import in IDA ICE (Phase 6): Download the processed output (gbXML or optimized IFC) and drop it straight into IDA ICE. The model maps into clean, simulation-ready zones instantly, cutting typical prep times down from days to minutes.
