Sketches a path in three-dimensional space, defines a cross-section, and projects the cross-section along the path to define a volume. The path can consist of both straight lines and arcs. 

Using the Type box, you can associate the volume with a design specification from the catalog database

In the Space Management task, you can create customized volumes in the location that you need and with the shape that you need using Place Volume Along Path . This command is especially useful for volumes that need to have an unusual, custom shape or that must negotiate around specific objects in the model. For example, if you need to leave adequate space for a crane, stretcher, or other equipment to reach a particular location, Place Volume Along Path allows you to specify the path where the equipment needs to travel, as well as the appropriate amount of clearance that must be left on all sides.

When you place a volume along a path, the software projects a two-dimensional cross-section along the path that you specify in the model to create the volume. The path determines the location of the volume in the model. The cross-section defines the shape and dimensions of the volume.

Defining Paths

When you define the path along which a cross-section will be projected, you can choose from straight lines or arcs. If you want to break the path at a particular point, you can select No Line . You can also control all aspects of the path by specifying the types of turns, the dimensions of the turns, and the plane for the path.

Defining Cross-sections

When you define the cross-section for the volume, you can select from a standard set of cross-sections, defined in the reference data, or you can sketch your own two-dimensional cross-section.

When you use a standard cross-sectional type, you can change the dimensions and the cardinal point of the cross-section on the Cross-Section tab on the Volume Properties dialog box. The cardinal point of the cross-section is important in determining the shape and location of the resulting volume. The cardinal point is the point at which you want the software to attach the cross-section to the path. All standard cross-section types have cardinal points from which you can choose.

For example, in this graphic, you can see that the cardinal point is located in the center of the cross-section. If the cardinal point were moved to another location, the actual path would be different.

When you sketch a cross-section, you must sketch the cross-section on the two-dimensional plane that is orthogonal to the first leg of the path. The software displays this plane, which is perpendicular to the path, as you sketch the cross-section. The cardinal point is defined as you sketch. In other words, the cross-section surrounds the path and is attached to the path exactly as you sketch it.

The faces of the volumes created using Place Volume Along Path can be located by the SmartSketch service.

Place Volume Along Path Ribbon

Sets options for placing volumes defined by a path and a cross-section projected along the path.

Properties

Displays the Volume Properties dialog box, which allows you to set properties for the volume that you are placing.

Path

Displays the Create Path ribbon, which allows you to define the path along which the volume will be created.

Cross-Section

Sets properties for the cross section. If you select one of the standard cross-sectional types in the Cross-Section box, this button displays the Cross-Section Tab (Volume Properties Dialog Box) to allow you to modify the properties of the cross-section. If you select Sketch as the cross-sectional type, this button displays the Create Path ribbon to allow you to sketch the two-dimensional cross-section. The Cross-Section button is only available after you define a path for the volume.

Finish

Places the volume along the specified path with the specified cross-section.

Cross-Section

Specifies the type of cross section that you want to project along the specified path. You can select a standard cross section defined in the reference data, or you can sketch your own custom cross section.

Name

Displays the default name for the space (as dictated by the active name rule), and allows you to type a different name, if needed.

Type

Specifies the type of volume. Selecting More from the list opens the Select System Dialog Box from which you can select a volume type. The Type list is populated by the reference data and can be customized on a model-by-model basis. For more information on customizing space management reference data, see the Space Management Reference Data Guide, available from the Help > Printable Guides command.

Space folder

Select the space folder in which to place the volume. You can create new folders using Create Space Folder. Select More from the list to open the Select Space Folder Dialog Box from which you can select an existing folder that is not currently listed.

Create Path Ribbon

Sets options for defining a new path.

Properties

Displays the Sketch Properties dialog box, which allows you to view properties for the path.

Finish Path

Displays the path in the active graphic view and returns to the Place Volume Along Path command.

Cancel

Cancels the changes that you have made and returns you to the model.

Edit

Allows you to modify and move the existing path. When you initially create a path, this option is only available after you place at least two points in the path. You can select a segment, a turn, or multiple segments to which you want to make modifications.

Create

Sketches the path or adds segments to an existing path.

Reference Point

Specifies that you are defining the first point of the path segment.

Second Point (Arc)

Specifies that you are defining the second point of an arc. This option only appears when you select Arc by Three Points or Arc by End Points in the Path Type list.

End Point

Specifies that you are defining the end point of a straight path segment or an arc.

Path Type

Specifies the type of line for the current segment in the path. To change the segment type, select a different type in the Path Type list.

  • Line - Specifies a straight line for the segment.

  • Arc by 3 Points - Specifies an arc by three points for the segment. The first point is the start of the arc, the second point is a point on the arc, and the third point is the end of the arc.

  • No Line - Specifies that you do not want the current segment of the path to have a line associated with it.

  • Arc by End Points - Specifies an arc by end points for the segment. The first point you click is the start of the arc; the second point you click is the end of the arc; the third point you click defines the plane, radius, and sweep angle of the arc.

  • Elliptical Arc - Specifies an elliptical arc for the segment. The first point you click is the start of the arc; the second point you click is the center of the ellipse; the third point you click defines the minor/major axis ratio and the sweep angle.

Plane

Activates options for selecting a working plane for the path.

  • Plan Plane - Defines the work surface as the XY plane. You can also press CTRL+1 to select this option.

  • Z Plane: X-West / Elevation Plane: East-West - Defines the work surface as the XZ plane. You can also press CTRL+2 to select this option. 

  • Section Plane: Y- South / Elevation Plane: North-South - Defines the work surface as the YZ plane. You can also press CTRL+3 to select this option.

  • Plane by Turn - Defines the work surface as the plane defined by an existing turn. You select the turn to set the plane. You can also press CTRL+4 to select this option.

  • Plane by Three Points - Defines the work surface using three points you define. You can also press CTRL+5 to select this option.

  • No Plane - Clears any work surfaces. The software does not project points that you place to any plane. You can also press CTRL+6 to select this option.

Lock Angle

Locks or unlocks the Angle box. This option appears for the Line path type.

Angle

Specifies the angle for the segment. This option appears for the Line path type.

  • None - Indicates that no special turn type is applied to the turn.

  • Bend - Specifies that the turn type between two segments is a bend. You can specify the angle of the bend in the Value box.

  • Cornice - Specifies that the turn type between two segments is a cornice. You can specify the radius of the cornice in the Value box.

  • Chamfer - Specifies that the turn type between two segments is a chamfer. You can specify the dimensions for setback A and setback B of the chamfer in the Value box. The dimensions of setback A and setback B for the chamfer must be the same.

The following graphic includes an example of each of the available turn types:

Value
