Description

A Part Prism.svg Part Prism is a parametric solid that can be created with the Part Primitives.svg Part Primitives command. It is the result of extruding a regular polygon along a straight path. In the coordinate system defined by its DadosPlacement property, the bottom face of the prism lies on the XY plane with its center at the origin and one of its vertices on the X axis.

Usage

See Part Primitives.

Example

Part Prism from the scripting example

A Part Prism object created with the scripting example below is shown here.

Properties

See also: Property editor.

A Part Prism object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:

Data

Attachment

The object has the same attachment properties as a Part Part2DObject.

Prism

  • DadosPolygon (IntegerConstraint): The number of sides of the polygon. The default is 6.
  • DadosCircumradius (Length): The radius of the circle that circumscribes the polygon, the distance from the center of the polygon to one of its vertices. The default is 2mm.
  • DadosHeight (Length): The height of the prism. The default is 10mm.
  • DadosFirst Angle (Angle): The angle between the extrusion direction of the prism and its positive Z axis, measured around its Y axis. The angle is positive towards its positive X axis. Valid range: 0° <= value < 90°. The default is . introduced in version 0.19
  • DadosSecond Angle (Angle): The angle between the extrusion direction of the prism and its positive Z axis, measured around its X axis. The angle is positive towards its positive Y axis. Valid range: 0° <= value < 90°. The default is . introduced in version 0.19

Scripting

See also: Autogenerated API documentation, Part scripting and FreeCAD Scripting Basics.

A Part Prism can be created with the addObject() method of the document:

prism = FreeCAD.ActiveDocument.addObject("Part::Prism", "myPrism")
  • Where "myPrism" is the name for the object.
  • The function returns the newly created object.

Example:

import FreeCAD as App

doc = App.activeDocument()

prism = doc.addObject("Part::Prism", "myPrism")
prism.Polygon = 5
prism.Circumradius = 10
prism.Height = 50
prism.FirstAngle = 22.5
prism.SecondAngle = 45
prism.Placement = App.Placement(App.Vector(1, 2, 3), App.Rotation(60, 75, 30))

doc.recompute()
