Cable Tray |
Up Previous Next |
This section describes how to use cable trays. The values that can be specified for cable trays are listed below. Group: The group to which the cable tray is assigned. The group controls the layer on which the cable tray is inserted. See the Cable Tray Groups section for more information. Starting Elevation: The starting elevation of the cable tray. The reference point for the starting elevation of the cable tray is set by the Vertical Alignment. See the Elevation section for more information. Ending Elevation: The ending elevation of the cable tray. The reference point for the ending elevation of the cable tray is set by the Vertical Alignment. See the Elevation section for more information. Vertical Alignment: Specifies the reference point used for the Starting Elevation and Ending Elevation.
Horizontal Alignment: Specifies the reference point for the cable tray construction line.
Width: The width of the cable tray, in inches. This size should be the actual exterior dimensions of the cable tray. The exact value is used to draw the cable tray for collision detection purposes. Depth: The depth of the cable tray, in inches. This size should be the actual exterior dimensions of the cable tray. The exact value is used to draw the cable tray for collision detection purposes. Radius: The inside radius of the fittings in the cable tray. Elbow Type: The graphic that is used for elbows in the cable tray. Tees and crosses look the same for both selections.
Hanger Type: The type of hanger. Controls whether hangers and their graphics are included.
Size: The size of the hanger, in inches. The size is used to control most of the dimensions of the hanger graphic. The support rod diameter will be equal to this size. Other dimensions will be scaled based upon this size. Hanger Depth: The distance the hanger extends below the item, in inches. Starting Offset: The distance from the start of the centerline to the location of the first hanger, in inches. Ending Offset: The distance from the end of the centerline to the location of the last hanger, in inches. Spacing: The distance between each hanger, in inches. Left Width: The distance the hanger extends to the left side of the centerline, in inches. If this value is 0, the hanger will be wide enough to support the item. If it is greater than 0, the hanger will extend exactly that distance to the left of the centerline. It is possible this distance will be less than the width of the item the hanger is supporting. In that case, you need to increase the width. A width greater than necessary to support the specific item can be used to support a rack of items or to allow for future expansion. Right Width: The distance the hanger extends to the right side of the centerline, in inches. If this value is 0, the hanger will be wide enough to support the item. If it is greater than 0, the hanger will extend exactly that distance to the right of the centerline. It is possible this distance will be less than the width of the item the hanger is supporting. In that case, you need to increase the width. A width greater than necessary to support the specific item can be used to support a rack of items or to allow for future expansion. Ending Elevation: The elevation where the support rods end. The support rods will be drawn from the item up to this elevation. See the Elevation section for more information. Layer System: See the Layer System section for more information. |
