Tessellate IFC Elements

Feature Group: Convert | IfcOpenShell / IfcPatch

This feature converts the geometry of selected IFC Elements to a mesh of triangles using IfcOpenShell IfcPatch module with 'TessellateElements' recipe.

Standard geometry operations can be performed on mesh without needing to resort to a sophisticated geometry library.

The IFC File must have a schema version IFC4 or more recent.

# Tessellate selected product elements in an IFC

class TessellateIfcElements_Instruction(BaseModel):
    sourceFileURL: str | None = "http://localhost:8002/IFC_SOURCE_FILES/AC20-FZK-Haus.ifc"
    tessellateIfcElements: TessellateIfcElements

class TessellateIfcElements(BaseModel):
    elementTypes: list[str] | None = ["IfcSpace"]
    forcedFacetedBREP: bool | None = False

class TessellateIfcElements_Result(BaseModel):
    resultPath: str # relative path of the result file (ifc)
    runtime: float | None = 0.0 # in seconds

The elementTypes gives the list of element for which we expect to change the geometry representation.

Note

Tessellate does not maintain the style (this is a known feature / bug). In the present state, tesselation should better not be used on the primary import.
