Add Void Space Cylinder ( Modeling )

• Creates a cylindrical void space that emulates a cylindrical cut in the steel or concrete member to which the cylinder is added.
• The void that is thus created may be for the purpose of permitting electrical, plumbing, or HVAC penetrations through the member.
• To begin adding the custom component , you can click the Add Void Space Cylinder icon or use Add Component . The icon can be found in the command group ' Model--Component ' for Toolbar Configuration (classic) or Ribbon Editor (lightning).

The Void Space Cylinder becomes a custom component of the member that you select to add it to.

• A typical procedure:
• 1. Navigate > Snap To Surface on a submaterial or the main material of the member to which you want to add the void.
  2. View > Relative Depth to move the work plane into the material.
  3. Select the member, click the icon, and locate two work points to designate the workline of the cylinder.
• If you add a void space to a concrete member, the volume of that space will be subtracted from the " Volume (cubic yards) " and " Volume (cubic feet) " reported on that concrete member's edit window.
• Adding a void to a steel member results in the " Weight of item " and " Surface area " reported on the member material's General Information window being reduced by the volume of material that is impinged upon by the void.

------ Void Space Cylinder settings ------

Diameter: A d istance (in the primary dimension " Units " or other units ). This sets the diameter of the void space cylinder.

Apply to: all materials or selected materials .

	" Voids " is turned on (checked) in Display Options . This void would be displayed as shown regardless of whether the choice made here was ' all materials ' or ' selected materials '.
	" Voids " is turned off (not checked) in Display Options . For the material to be removed by the void as shown here, " Apply to " must be set to ' all materials ' or to ' selected materials ' with the material shown in the list .
	" Voids " is turned off (not checked) in Display Options . " Apply to " is set to ' selected materials ', but the main material of the beam shown here is not included in the list . As a result, the material is solid since no material is removed by the void.

' all materials ' results in all materials that are associated with the member you added this component to being voided wherever they are impinged upon by the void.

' selected materials ' lets you select which materials of this component's member you want to be affected by the void. Only those materials that you select by pressing " Add " to place them in the list will be voided when they are impinged upon by the void. For steel materials, the " Weight of item " and " Surface area " reported on the member material's General Information window will be reduced only if those materials are listed.

Example of a "selected materials" list:

When " Apply to " is set to ' selected materials ', only materials assigned pcmk_1 or pcmk_2 or pcmk_3 will have material removed when the void passes through them.

• To add materials to the list, press the " Add " button. The program lets you select from the submaterial piecemarks of materials associated with the member to which you added this Void Space Cylinder component.
  
  
  
  
• To remove a material from the list, select it then press the " Delete " button.
