Requirements for Building Parts

This task lists certain requirements for building parts. You should incorporate these when you are building parts, or part behavior will not be as expected. Instructions for building parts are given elsewhere in this manual, including in the section Building Parts. Connectors are explained in the section Connectors. Instructions for using the Part Design product are given in the Part Design User Guide. The column headings below mean:

Part Type: The part type to which the requirements apply.
Geometrical requirements: The requirements you must incorporate when you are creating the geometry for the part.
Properties: The requirements you must incorporate when defining these properties.
Override parameters: The properties shown here must be defined as override.
Connector type: The type of geometry needed for creating connectors.

Part Type	Geometrical Requirements	Properties	Override Parameters	Connector Type
Straight (stretchable)	Regular object: No requirements Light object: No geometry required	No requirements	Piping Design, Raceway and Conduit Design, Tubing Design, Waveguide Design: XXXLength where XXX stands for an application specific object, such as PipeLength HVAC Design: Diameter Width Height DuctLength	Regular object: Use existing geometry Light object: No geometry required
Bendable/Flexible	Regular object: The Profile sketch and Rib feature need to exist in the primary PartBody, i.e. "Double". In addition, you should have another PartBody named "Hidden". The Spine sketch needs to exist in this PartBody. There should be an OpenBody named "RibPath" which should be empty. Light object (bendable only): No geometry required	No requirements	Piping Design, Raceway and Conduit Design, Tubing Design, Waveguide Design: No override parameters	New geometry
Elbow	No requirements	Piping Design only: OK to cut: Yes for cut elbows No for elbow with set angles	Piping Design, Raceway and Conduit Design, Tubing Design, Waveguide Design: Cut Angle HVAC: Diameter Width Height DuctLength	Use existing geometry
Inline Part	No requirements	No requirements	HVAC: Diameter Width Height	Use existing geometry
Inline Weld	Regular object: No requirements Light object: No geometry required	No requirements	Outside Diameter Weld Offset Nominal Size	Regular object: Use existing geometry
Branch Weld	Regular object: No requirements Light object: No geometry required	No requirements	Outside Diameter Outside Diameter2 Weld Offset Nominal Size Nominal Size2	Regular object: Use existing geometry Light object: New geometry
HVAC Only: Round Access Cover	No requirements	No requirements	Diameter Thickness	Use existing geometry
HVAC Only: Rectangular Access Cover	No requirements	No requirements	Width Height Thickness Angle	Use existing geometry
HVAC Only: Radius Corner Access Cover	No requirements	No requirements	Width Height Thickness Angle	Use existing geometry
Insulation Part	No geometry required	Insulation thickness property should have a value	No override parameters
Loose Parts Bolt Nut Locking Device	No geometry required	No requirements	No override parameters
