TypeIds and properties

Use TypeIds with create_object, create_objects, doc.addObject, and object inspection. This page is a curated map; use runtime introspection for exact active-build availability.

Sketcher TypeIds

Sketcher::SketchObject
Sketcher::SketchObjectPython

Common sketch members:

Geometry
Constraints
OpenVertices
Placement
Support
AttachmentSupport
MapMode

Use get_sketch for normalized geometry and constraint serialization.

Spreadsheet TypeIds

Spreadsheet::Sheet

Common sheet operations:

set
get
getContents
setAlias
getAlias
clear
mergeCells
splitCell
insertRows
removeRows
insertColumns
removeColumns

Use MCP spreadsheet tools first because they normalize cells, aliases, ranges, and recompute.

TechDraw TypeIds

TechDraw::DrawPage
TechDraw::DrawSVGTemplate
TechDraw::DrawViewPart
TechDraw::DrawViewDraft
TechDraw::DrawProjGroup
TechDraw::DrawProjGroupItem
TechDraw::DrawViewSection
TechDraw::DrawViewDetail
TechDraw::DrawViewDimension
TechDraw::DrawViewBalloon
TechDraw::DrawLeaderLine
TechDraw::DrawViewAnnotation
TechDraw::DrawViewSymbol
TechDraw::DrawViewImage
TechDraw::DrawHatch

Common properties:

Source
Direction
Scale
ScaleType
X
Y
Rotation
Caption
PageResult
Template
Views

Mesh TypeIds

Mesh::Feature
Mesh::FeaturePython

Common properties:

Mesh
Placement

Mesh objects are faceted and should not be treated as final parametric solids.

Draft / BIM / FEM TypeIds

Draft and BIM often create Python-backed objects with generic TypeIds plus a Proxy.Type or workbench-specific proxy. Inspect both:

print(obj.TypeId)
print(getattr(getattr(obj, "Proxy", None), "Type", None))

FEM objects are analysis-specific. Discover available FEM TypeIds with:

print(doc.supportedTypes())

Property discovery

Use:

for prop in obj.PropertiesList:
    print(prop, getattr(obj, prop))

Use richer metadata when available:

print(obj.getTypeIdOfProperty(prop))
print(obj.getGroupOfProperty(prop))
print(obj.getDocumentationOfProperty(prop))
print(obj.getEditorMode(prop))

Expression binding

Any expression-capable property can be driven from a spreadsheet alias:

obj.setExpression("Length", "Spreadsheet.PlateLength")

Inspect expressions:

for prop in obj.PropertiesList:
    try:
        expr = obj.getExpression(prop)
    except Exception:
        expr = None
    if expr:
        print(prop, expr)

Agent rule

Never guess a property name on a live model. Inspect PropertiesList or use a typed MCP tool that already knows the property schema.
