Simplebim 11.0 SR8 (3.3.2026)

Bug Fixes

• Bug fixed in Copy property Values -tool when copying from multiple properties with the same name into a property on the same object. This bug was introduced in SR7 and fixed in SR8.

New Features

• New 'Clear Spatial Containment' -tool for cleaning up the spatial containment by removing objects from their spatial containers.

Enhancements

• Dataflow palette: Configuration added for opening dataflows with sections collapsed.
• Dataflow palette: Function to import a dataflow from file as the current dataflow added.
• Add Location Using Nearby Space: Operational reliability improved when used multiple times for same model (Fixed connection changed to dynamic one)

• Add or Modify Group -tool: object selection configuration simplified
• Copy Property Values -tool: performance optimizations
• Split objects -tool: improved handling of special geometry cases

Bug Fixes

• Bug fixes to geometry operations used mainly in splitting
• Map GUIDs -tool: Bug fixed that in some cases caused the last GUID set to be missing.
• Bug fixed in splitting nested spaces (spaces inside other spaces)
• Calculate quantities -tools: bug fixed in handling excluded objects when the target was a group
• User interface optimizations for preventing Windows from running out of resources, which could cause Simplebim to crash.
• Bug fixed in assigning the include/exclude status to derived objects when the original object was an assembly

Simplebim 11.0 SR6 (10.12.2025)

Enhancements

Bug Fixes

• Some memory leaks fixed in dataflow editing that could cause an application crash when Simplebim was used for a long time without closing.
• Add or Replace Group -tool: Sime illegal configuration combinations removed.

• Objects -palette: bug fixed that caused the application to crash when a new rule based group was added without defining a rule.
• Groups: bug fixed in using yes/no rules for rule based group
• Groups: application crash fixed in saving complex rule based groups as a group template file.

Simplebim 11.0 SR5 (4.11.2025)

Enhancements

• Improved ‘design echo’. The user interface now better automatically and consistently updates to show changes made to the model by dataflows. This helps to better understand the effect of running dataflows and individual dataflow steps.

• Dataflows: Added option to copy one or two values from nearby space to create Space Identity property to ‘Add Location Using Nearby Space’
• Dataflows: Added option to activate/deactivate splitting and option to copy one or multiple values from location prisms to objects to ‘Add Location Using Prisms (Optional Split)’
• Dataflows: Target limited to Space only for ‘Add Location Using Nearby Space’, ‘Derive surface Objects for Space Wall’ and  ‘Derive surface Objects for Space Floor’
• Improved drag&drop for dataflow steps. A menu is displayed at drop for choosing the action (move/duplicate) and target (step/section/steps in section)
• Option added for adding a new dataflow section header above the selected step.
• Improved handling of invalid containers in IFC import: IfcDistributionPort is now filtered out from containment as well as containers containing themselves (recursion)
• Import support for IfcPropertyEnumeratedValue: If the value is not a list it is converted to IfcPropertySingleValue at import

Bug Fixes

• Bimsheet: bug fixed in reading Bimsheets that show Group Category data
• Model Splitter: bug fixed that was in some cases leaving the original objects in addition to the new split objects when the location prisms were merged in  the same session and the split objects had both 3D and 2D geometry
• Bug fixed in maintaining configuration when a dataflow with only one step is opened in the Dataflow palette
• Bug fixed in adding an ‘ungrouped group’ using the ‘Add or Modify Group’ -tool
• Bug fixed in copying properties other than the name of a group to objects in the group
• Bug fixed in exporting the predefined type property for spaces in IFC4 and IFC4.3 models

Simplebim 11.0 SR1 (26.6.2025)

New Features

• New Delete objects tool for permanently deleting any selection of objects
• New tool for generating location prisms along alignments (IFC4.3)
• New tool for moving objects along alignments (IFC4.3)
• Dynamic dataflow step names. Names of text and choice dataflow configuration items (not yet other types) can be used as variables in dataflow step names, for example: Add [Property Name] -property

• The Convert Objects -tool will no longer convert to object classes that don’t exist in the IFC version used by the current model.
• The Copy Property Values -tool can now take multiple source properties

• Bug fixed in case sensitive comparisons in queries
• Bug fixed in applying a Excel template using the Apply Template tool when the file name of the template contains square brackets. Same applied to all tools that take a file name, for example merging IFC models.

• Bug fixed in exporting geometry that was modified in Simplebim (subtract, union, intersect) into IFC

• Bimsheet protected against cases where the GlobalID property is included in the IFC import and used in a Bimsheet that adds the same property again as the last column.
• Bug fixed in exporting grids to IFC when the target for the export was ‘All’
• Bug fixed in using classification item groups as a target in tools and dataflows when the classification it was not a direct child of the classification system
• ‘Generate Child Groups by…’ dataflows fixed to work with all group categories (previously only Generic Group)

  • Adding properties
  • Copying property values
  • Adding and modifying groups
  • Including/excluding objects and properties
