Cable Geometry Form

Use the Cable Geometry form to refine the parabolic alignment of a cable.

Line Object Type drop-down list. This drop-down list displays that the currently selected line object is a cable.

Cable Type drop-down list. Use this drop-down list to select the type of cable (minimum tension at End I or at End J, tension at I-End, tension at J-End, horizontal tension component, maximum vertical sag, low-point vertical sag, undeformed length).
Section Property drop-down list. Use this drop-down list to choose a section property for the cable.
Start X, Y, Z and End X, Y, Z display boxes. These display boxes show the X, Y, and Z coordinates of the beginning and end of the cable.
Number of Linear Segments edit box. Use this edit box to specify the number of segments used to define the cable.
Added Weight Per Unit Length edit box. Use this edit box to specify additional weight for each length of the segment.
Projected Uniform Gravity Load edit box. Use this edit box to specify the projected uniform gravity load for the cable.
Tension at I-End edit/display box. When Tension at I-End is selected for the Curve/Cable Type, the default value can be changed by typing a new value in this edit box. When other curve/cable types are chosen, the value in this display box cannot be edited.
Tension at J-End edit/display box. When Tension at J-End is selected for the Curve/Cable Type, the default value can be changed by typing a new value in this edit box. When other curve/cable types are chosen, the value in this display box cannot be edited.
Horizontal Tension Component edit/display box. When Horizontal Tension Component is selected for the Curve/Cable Type, the default value can be changed by typing a new value in this edit box. When other curve/cable types are chosen, the value in this display box cannot be edited.
Maximum Vertical Sag edit/display box. When Maximum Vertical Sag is selected for the Curve/Cable Type, the default value can be changed by typing a new value in this edit box. When other curve/cable types are chosen, the value in this display box cannot be edited.
Low-Point Vertical Sag edit/display box. When Low-Point Vertical Sag is selected for the Curve/Cable Type, the default value can be changed by typing a new value in this edit box. When other curve/cable types are chosen, the value in this display box cannot be edited.
Length edit/display box. When the Cable - Length option is selected for the Curve/Cable Type, the default value can be changed by typing a new value in this edit box. When other curve/cable types are chosen, the value in this display box cannot be edited.
Keep as Single Object option. Use this option to treat the cable as a single line object during analysis.
Break into Multiple Equal Length Line Objects option Use this option to treat the cable as being comprised of multiple line objects during analysis.
Break into Multiple Line Objects with Equal Projected Length on Chord option Use this option to treat the cable as being comprised of multiple line objects of equal length as projected on the chord during analysis.
Coordinate System drop-down list. Use the drop-down list to select a coordinate system other than global if one has been defined (see Define Coordinate Systems/Grids for more information about defining a coordinate system).
Units drop-down list. Use the existing units or use the drop-down list to select revised units for working with the data on the form.
Refresh button and the Computed Point Coordinates for Linear Segments (Undeformed/Deformed Cable Geometry) spreadsheet. Click the Refresh button to update the Computed Point Coordinate for Linear Segments (Undeformed/Deformed Cable Geometry) spreadsheet area after making selections or changes in the other areas of the form. The cells in this spreadsheet cannot be edited directly.
Use Undeformed Geometry for Cable Object and the Use Deformed Geometry for Cable Object options. Use these options to change the display in the spreadsheet to show the undeformed or deformed values for coordinates, sag, distance and relative distribution of the points defining the cable.
