# TypeIds and properties

> Common Parashell object TypeIds, property patterns, and expression-binding rules

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.

## Core application TypeIds

```text theme={null}
App::DocumentObjectGroup
App::Part
App::Link
App::LinkGroup
App::FeaturePython
App::Annotation
```

Common properties:

```text theme={null}
Label
Visibility
Group
Placement
ExpressionEngine
```

## Part TypeIds

```text theme={null}
Part::Feature
Part::FeaturePython
Part::Part2DObject
Part::Part2DObjectPython
Part::Box
Part::Cylinder
Part::Sphere
Part::Cone
Part::Torus
Part::Prism
Part::Plane
Part::Line
Part::Circle
Part::Ellipse
Part::Polygon
Part::Extrusion
Part::Revolution
Part::Sweep
Part::Loft
Part::Fuse
Part::MultiFuse
Part::Cut
Part::Common
Part::Compound
Part::Fillet
Part::Chamfer
Part::Thickness
Part::Mirror
```

Common primitive properties:

```text theme={null}
Length
Width
Height
Radius
Radius1
Radius2
Angle
Placement
Shape
```

Boolean properties:

```text theme={null}
Base
Tool
Shapes
```

## PartDesign TypeIds

```text theme={null}
PartDesign::Body
PartDesign::Feature
PartDesign::Pad
PartDesign::Pocket
PartDesign::Revolution
PartDesign::Groove
PartDesign::AdditivePipe
PartDesign::SubtractivePipe
PartDesign::AdditiveLoft
PartDesign::SubtractiveLoft
PartDesign::Fillet
PartDesign::Chamfer
PartDesign::Draft
PartDesign::Thickness
PartDesign::LinearPattern
PartDesign::PolarPattern
PartDesign::Mirrored
PartDesign::MultiTransform
PartDesign::ShapeBinder
PartDesign::SubShapeBinder
PartDesign::Plane
PartDesign::Line
PartDesign::Point
PartDesign::CoordinateSystem
PartDesign::AdditiveBox
PartDesign::AdditiveCylinder
PartDesign::AdditiveSphere
PartDesign::AdditiveCone
PartDesign::SubtractiveBox
PartDesign::SubtractiveCylinder
PartDesign::SubtractiveSphere
PartDesign::SubtractiveCone
```

Common feature properties:

```text theme={null}
Profile
BaseFeature
Length
Length2
Type
Reversed
Midplane
Offset
Angle
Axis
Radius
Size
Support
AttachmentSupport
MapMode
```

## Sketcher TypeIds

```text theme={null}
Sketcher::SketchObject
Sketcher::SketchObjectPython
```

Common sketch members:

```text theme={null}
Geometry
Constraints
OpenVertices
Placement
Support
AttachmentSupport
MapMode
```

Use `get_sketch` for normalized geometry and constraint serialization.

## Spreadsheet TypeIds

```text theme={null}
Spreadsheet::Sheet
```

Common sheet operations:

```text theme={null}
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

```text theme={null}
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:

```text theme={null}
Source
Direction
Scale
ScaleType
X
Y
Rotation
Caption
PageResult
Template
Views
```

## Mesh TypeIds

```text theme={null}
Mesh::Feature
Mesh::FeaturePython
```

Common properties:

```text theme={null}
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:

```python theme={null}
print(obj.TypeId)
print(getattr(getattr(obj, "Proxy", None), "Type", None))
```

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

```python theme={null}
print(doc.supportedTypes())
```

## Property discovery

Use:

```python theme={null}
for prop in obj.PropertiesList:
    print(prop, getattr(obj, prop))
```

Use richer metadata when available:

```python theme={null}
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:

```python theme={null}
obj.setExpression("Length", "Spreadsheet.PlateLength")
```

Inspect expressions:

```python theme={null}
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.
