Pipe and Plumbing Cap Properties

Property Name Description
Base Offset <numeric value>
  • Displays the Base Offset set in the Place dialog while placing a pipe. The value reflects when a pipe is being modified.
Body | Diameter Positive <numeric value>
  • Sets cylinder diameter for main body of coupling, higher than End diameters.
Cap | Length Positive <numeric value>
  • Sets the distance between the connect point (End1) and the start of the dome.
Connection 1 | Length (L1) Positive <numeric value>
  • Sets length of male or female connection for End1.
Set End Type to male or female to see change in geometry. If End Type is flange, the connection point moves.
Connection 2 | Length (L2) Positive <numeric value>
  • Sets length of male or female connection for End2.
Convolutions Positive <numeric value>
  • Preset number of convolutions based on movement capability and/or spring rate, making bellows flexibility possible.
The number of convolutions depends upon the amount of movement the bellows must accommodate or the force that must be used to accomplish this deflection.
Connection | End Type fl -<numeric value>
  • Sets and sizes end with a flange connection.
m -<numeric value>
  • Sets and sizes end with a male connection.
fe -<numeric value>
  • Sets and sizes end with a female connection.
Separate End Type entries for each End Spec with a semi colon.

Example: fl-2;fe-.13 creates a flange at End1 with size 2, and a female connection at End2 with an overall reduction of component's dimensions of .13

For Flex Bellows, The End Type is selectable, either:
  • 1-Flange – Adds flanges to both ends.
  • 2-Plain – Sets no flanges to the ends.
Dome Height Positive <numeric value>
  • Sets the height of the dome bulge.
Flange1 Diameter,

Flange2 Diameter

Positive <numeric value>
  • Sets the outer diameters of flanges for Flange End Type flex bellows.
Female Connection Diameter Positive <numeric value>
  • Reduced branch outside diameter at End2.
Hub Length Positive <numeric value>
  • Sets the length of the hub body.
Inlet | Outer Diameter Positive <numeric value>
  • Outside inlet diameter of socket.
Male Connection Diameter Positive <numeric value>
  • Main branch outside diameter at End1 of union fitting.
Minimum Length Positive <numeric value>
  • Sets minimum length. Duct cannot be manipulated to segments smaller than Minimum Length property.
Outlet | Outer Diameter Positive <numeric value>
  • Outside outlet diameter of socket.
Pipe Length /

Total Length (L)

Positive <numeric value>
  • Sets duct length with a positive value greater than or equal to value of Minimum Length property.
  • Displays flex linear length. Set by default.
Pipe Outer Diameter Positive <numeric value>
  • Outside pipe diameter.
Note: The value includes also the 2xWall Thickness.
Ridge Distance Positive <numeric value>
  • Sets the spacing of ridges.
Ridge Numbers Positive <integer>
  • Sets the number of ridges.
Slope Method
  • Rise/Run
  • Degree
  • % Precent
<active method set in Apply Slope>
  • Displays slope method currently set in the Apply Slope setting.
Slope Value <numeric value>
  • Displays slope value appropriate with the active Slope Method.
Tab | Height

Tab | Length

Tab | Width

Positive <numeric value>
  • Sets the cubical dimensions equally for the tabs on both sides of the body.
