Hoists

The hoist tools in the Vectorworks Spotlight program assist with the design and documentation of overhead stage rigging equipment. Hoists are placed in a drawing that normally already contains lighting, staging, audio equipment, and the loads that will hang from the hoists. In addition, hoists can be used in conjunction with Braceworks rigging drawings and calculations. A suite of tools and commands assists you with creating all the diagrams and paperwork needed for rigging work.

Placing Hoist Origins

The hoist origin serves as a reference point for associated hoists. Several hoist origins can be placed in the drawing, and different hoists can refer to different hoist origins. The coordinates displayed for each hoist are based on its position relative to the assigned hoist origin.

The first time you use the tool in a file, a properties dialog box opens. Set the default properties. The properties can be edited from the Object Info palette.

Selecting and Assigning Hoist Origins

Command	Path
Assign Origin to Selected Hoists	Spotlight > Hoists

Paired hoists and hoist origins can be quickly selected. Right-click on the hoist and select Select Hoist’s Origin from the context menu, or right-click on the hoist origin and select Select Origin’s Hoist from the context menu.

In addition, selected hoists can be quickly set to a specific hoist origin object, or a new hoist origin can be created.

3 Click on the existing hoist origin, or click in a blank area of the drawing to create a hoist origin for the selected hoists.

Alternatively, right-click on the hoist origin and select Assign to Selected Hoists from the context menu.

The selected hoists are assigned to the hoist origin. The Measured From parameter in the hoist Object Info palette updates to reflect the new hoist origin.

Setting Hoist Heights

Several commands assist with setting the height of the hoist hooks in relation to loads and associated items or to each other. While these can be set individually from the Object Info palette, using these commands is much easier when editing more than one hoist at once.

Setting the Low Hook Based on the Load Trim

This command is useful when setting the height of hoists to their associated truss or hanging position loads. By specifying the bottom height of the load, the hoists, and optionally the load, automatically adjust to the correct height.

Command	Path
Specify Selected Load Trims	Spotlight > Hoists

1 Switch to a side 3D view, like Left, Right, or Front, that shows the hoists and the load.

2 Select the hoists to adjust. To also adjust the height at the bottom of the load, select the load as well.

The hoists are set to the adjusted Low Hook Height, while accounting for the Low Hook to Load Trim offset. If the load was also selected, its Z height (elevation) is also set.

Setting the Low Hook Based on a Selected Load

When it is not obvious or easy to determine the elevation of a load, the height of selected hoists can still be set to an object in the drawing (usually a truss or hanging position). The low hook height of several hoists can also be set to that of another hoist, quickly setting all the hoists to the same height without needing to know the specific height.

Command	Path
Set Selected Load Trims	Spotlight > Hoists

1 Switch to a side 3D view, like Left, Right, or Front, that shows the hoists and the load.

2 Select the hoists to adjust. To also adjust the height at the bottom of any other objects at the same time, select them as well.

5 The hoists are set to the adjusted Low Hook Height. If other objects were selected, the Z height (elevation) of their bottom height is also set.

Setting the High Hook Height

The high hook height of selected hoists can be automatically set to the height of a clicked point. Only selected hoist objects are adjusted by this command (no other drawing objects can be selected).

Command	Path
Set Selected High Hook Height	Spotlight > Hoists

4 Click on the reference object, such as the bottom of a support structure, or another hoist. The selected object is highlighted.

Setting Individual High Hook Height

The high hook height of hoists can be automatically set to a clicked point, one by one. The hoists do not have to be set to the same high hook height. Only hoist objects are adjusted by this command (no other drawing objects can be selected).

Command	Path
Set Individual High Hook Heights	Spotlight > Hoists

3 Click on the first hoist, which is highlighted. Click on its trim point, which is usually a support structure, but can be another hoist.

5 When finished assigning high hook heights, click in a blank area of the drawing.

Bridles

Creating bridles is a common practice for event riggers. Vectorworks Spotlight offers a suite of commands and tools for designing and analyzing bridles and their connected support structures. With a Braceworks license, you can perform load calculations to assess the structural stability of the rigging system. When the design is complete, bridle assembly diagrams and parts lists can be easily generated for the riggers on-site.

Workflow: Pre-rigging the Event

At the start of a rigging project, create a “house file” for the venue that defines the available rigging points and their load limits. Once the “house” is modeled, insert the rigging structures and loads required by the event. Then insert the bridles needed to support the event rigging.

1 Create a house file for the venue. This model can be reused to pre-rig other events in the same space. Specify the basics of the drawing, such as establishing the layer scale, creating layers, setting up Spotlight preferences, and so on. Model the venue space.

Create layers to suit your rigging needs. To pre-rig a trade show, for example, place each booth on a separate design layer. The bridle paperwork can be organized by layer to create a separate parts list for each booth.

2 Use the Insert House Rigging Point tool, the Insert House Rigging Point at Selection command, and the Structural Member tool to define the available rigging points where bridles can attach. If the existing points are inadequate, use the Insert Mother Grid tool to place a truss system in the drawing.

3 Define the load limits for the house rigging points by setting their Allowable Force values.

4 When the house file is complete, model the event rigging. Insert trusses and lighting pipe. Add drops, such as hoists and dead hangs, to suspend the rigging system. Add load objects such as lights, speakers, video screens, and so on, or insert a point load or distributed load with the Insert Load tool.

5 Manage the bridle inventory. Select Manage Bridle Parts to specify the available parts and their properties.

8 From the Bridle Configuration dialog box, adjust how specific bridles are built from the available parts.

9 Calculate the forces applied to the rigging system (Braceworks required). Make changes to the system as needed.

It is recommended that you calculate forces throughout the design process (Braceworks required), to adjust the design for viable rigging.

• Select the Bridle Report command to create a bridle parts worksheet. The data can be sorted to assist with organization and assembly.

• Select Create Bridle Assembly Diagrams to generate diagrams, and optional parts lists, for the bridles.

Inserting House Rigging Points

House rigging points are defined early in the design process. They represent the existing points in a venue where mother grids and bridles can be inserted. Use the Insert House Rigging Point tool to place house rigging points in the drawing.

Bridles can also be inserted on and snapped to structural members, if the option to Use Structural Member as House Rigging Point is enabled from the Bridle Preferences.

1 Click the tool, and then click Preferences to set the default properties for house rigging points.

2 Click Symbol on the Tool bar. From the Resource Selector, double-click a resource to activate it.

Alternatively, from the Resource Manager, either double-click the house rigging point symbol to insert or right-click on the house rigging point symbol and select Make Active from the context menu.

The house rigging point is inserted in the drawing, with a display of the forces.

Click and drag the label control point to move the displayed forces. Select Text > Size to resize the text if needed.

5 Specify the Allowable Force X/Y/Z values on the Object Info palette to set the load limits of the rigging point.

Defining the Element Coordinate System

For structural engineering purposes, you can define the element coordinate system of a house rigging point. For example, rotate the Force X/Y/Z values for alignment to a structural member.

3 Click in the drawing to define the force orientation. For example, click on the centerline of a beam to define the forces in the beam direction.

Alternatively, use the Rotate tool to change the force orientation, or set the Rotation from the Object Info palette.

The forces are oriented in the specified direction. To calculate the forces, see Performing Calculations (Braceworks required). If the forces were calculated previously, the calculation results automatically adjust to the new orientation.
