In the Electrical Part Design workbench, select
Insert > Protective Covering
.
Select the From scratch selection mode.
The dialog box appears as:

In the Type list, select the type.
In the Thickness box, enter a value for the
thickness of the protective covering.
Optional: Click More>>
and set other parameters.

Parameters are displayed depending on the selected covering type.
Notes:
- The bend radius is not taken into account when computing
the segment using the standard algorithm. It is only used
with the FLEX algorithm. However, this parameter lets you
create knowledge rules.
- The flexibility slider sets the stiffness used when
computing segments using the
Flex Algorithm.
- The line type defines how coverings will be represented
on drawings.
- To set your own drawing line type, select a value
in the Line type list.
- To represent the covering in double line (projection)
mode, select the No line
type check box.
- You can set a default line type in Tools > Options... > Equipment > Electrical Discipline > Electrical Assembly Design > Electrical Geometry Management > Protective Covering Instantiation area.
Set the placement mode to Center.

The Center mode lets
you center the protective covering on a point. The length of
the covering on either side of this point is the same.
For
information about other placement modes, see
Adding a Protective Covering.
Specify a value in the Length box of the
Instantiate Protective Covering dialog box, for example enter 100mm.
Click Set as Preferred Length if you want to set the defined length as the preferred length of the
protective covering.
The Preferred Length is the length of protective covering defined during its creation.
In the specification tree or the geometry area, select
a segment.
The protective covering is centered on the point (segment
end, protective covering end, support entry or exit point) nearest
your selection. This point highlighted in blue when you move the pointer
over a segment is the reference point.

Optional: To move the center
point to another location, do one of the following:
- Drag the Center Point label along the
center curve.
- Double-click the Center Point label
and, in the dialog box that opens, enter a value in the
Distance box then click OK.
- Double-click the distance label and, in the dialog box
that opens, enter a value then click OK.
Click OK when done.
