Fittings assigned to a cable tray family
A fitting family must be assigned to each parameter in order to model a
run of conduit or cable tray. Even if you are not modeling a condition that
requires a tee, you still must have a fitting family assigned for tees. It may
seem counterintuitive to assign fittings to a system family without fittings,
but it is necessary in order for the runs to be modeled. When you model a
run without fittings, the fittings used have a value of Bend for their Bend
Or Fitting parameter. For runs modeled using fittings, the parameter value
is Fitting. This can be useful information when scheduling conduit or cable
tray.
The bend radius for cable tray elbows is set to the width of the cable tray
by default. The Bend Radius Multiplier parameter can be used to define a
bend radius for different types within the system family. The bend radius of
an elbow can be modified directly in the model by selecting the fitting and
editing the temporary radius dimension that appears, as shown in
Figure
13.35
. The bend radius for conduit elbows is determined by a lookup table
defined in the fitting family.
