The path modifier creates a surface defined by one longitudinal profile and a set of transverse profiles, with the path defined as:

a polyline with a width value (the polyline is the center line) in Pathway Path mode, or

a polyline as a boundary (with a generated center line based on the boundary) in Boundary Path mode. The center line remains defined within the bounds of the area of the modification defined by this object.

After drawing the path, shape the modifier by editing the center path (longitudinal profile) and by adding as many transverse profiles as needed. To edit the longitudinal and transverse profiles, view each profile section in an editing mode. The profile section displays the overall length of the profile, with vertices on each elevation change. Interactively add vertices and change the elevation and grades of existing points, snapping to existing geometry when Show other objects while in editing modes is selected in the Vectorworks preferences.

The modifier can be applied to the existing or proposed site model; the site model is modified when the site model is updated. Draw a path with the Site Modifiers tool, or draw a polyline and then select the Create Objects from Shapes command to change it to a pathway path or boundary path modifier (see Creating objects from shapes).

To create a pathway path or boundary path modifier:

Click the tool and mode.

Select the polyline creation mode; see Polyline tool.

Click to set the modifier object’s start point.

Click to set the end of the segment and the beginning of the next. Continue drawing segments in this manner until the path is complete. Return to the start point (for boundary configuration), or simply double-click to finish creating the modifier path.

In Pathway mode, the Site Modifier: Pathway Mode dialog box opens. Specify the width of the path modifier.

In Top/Plan view, add transverse profiles to the path as needed by clicking Add Profile from the Object Info palette, and then clicking on the modifier to create a profile at that location.

From the Object Info palette, edit the longitudinal and transverse profiles as needed to shape the modifier. Change the location of the modifier with the Reshape tool (see Reshaping the modifier path or boundary) or through the Object Info palette.

In Top/Plan view, click the drop-down context menu to access editing commands.

In object editing mode, adjust the profile's elevation and grade

Normally, create grade limits around the modifier. The parameters can be edited from the Object Info palette.

Parameter	Description
Simplification Tolerance	Enter a positive value to redefine the horizontal distance between the closest parts of two neighboring portions of the modifier. A longer distance simplifies the modifier polygon, reducing the number of source points that modify the site model. A shorter distance increases the number of source points that modify the site model. A value of 0 (zero) does not simplify the modifier.
Modifier Vertex Count	Displays the number of vertices created by the site modifier to modify the site model
Apply To	Specifies whether the site modifier applies to the existing or proposed site model
Update Site Model	Updates the site model with any site model modifications that have occurred. If the update causes the site model contours to fall outside the minimum/maximum elevation range specified in the site model settings, an alert displays, allowing the range to be adjusted.
Configuration	Indicates the type of modifier object
Show the surface in 3D	In 3D views, represents the modifier with a 3D mesh. This is convenient when working with a modifier independently of a site model, or when it's helpful to view the site modifier on the surface of the site model in 3D views. Deselect the option to view only the effects of the modifier on the site model.
Vertical sides for inner modifiers (closed modifiers only)	Determines whether inner modifiers create a transitional surface (when deselected) or a vertical retaining edge (when selected) Vertical sides for inner modifiers deselected (on the left) and selected (on the right)
Longitudinal Profile	Define the elevation changes along along the path modifier, and set the profile appearance
Edit Profile	Enters editing mode for the selected profile, for Editing aligned hardscapes or modifiers with profile lines
Start Elevation End Elevation	Enter the starting and ending elevation of the modifier; alternatively, enter one of the elevations and enter a Slope value to automatically calculate the other elevation
Slope	Enter the slope value; alternatively, when the Start Elevation and End Elevation are entered, the slope displays
Realign Elevations	If changes occurred to an elevation, resets the affected vertex elevations
Send to Surface	Sends the profile line to the surface of the site model
Profile Line Class Profile Text Class	Select <Site Modifier Class> to place the profile in the same class as the modifier; select a class, or create a new class, to control profile line appearance and visibility
Elevation Marker	Select the elevation indicator type
Elevation Marker Factor	Specifies the scale factor of the elevation marker
Slopes Grade Def	Determines the how the Slope is calculated and displayed
Show profile line	Toggles the display of all profile line parameters (name, slope, elevation, and markers)
Show profile names	Toggles the display of the profile names
Show slopes	Toggles the display of all slope values
Arrow indicates downward	When Show slopes is selected, adds an arrow to indicate which side slopes down
Show vertex elevation	Toggles the display of all vertex elevations
Show profile line markers	Toggles the display of markers at the ends of the profile line
Profile Line Marker Styles	Opens the Set Marker Style dialog box, to select the profile marker type at each end of the profile line; markers can be the same (Match beginning) or different (Differentiate) at each end of the section line
Transverse Profiles	Transverse profiles are always perpendicular to the center line; define the elevation changes along each transverse profile and set the appearance
Profile	Scrolls through the profiles, highlighting the selected one; click the center button to highlight the current profile
Name	Displays the name of the currently selected profile
Profile Line Class Profile Text Class	Select <Site Modifier Class> to place the profile in the same class as the modifier; select a class, or create a new class, to control profile line appearance and visibility
Slopes Grade Def	Determines the display of the slope units
Show profile lines	Toggles the display of all profile line parameters (name, slope, elevation, and markers)
Show profile names	Toggles the display of all profile names
Show slopes	Toggles the display of all slope values
Arrow indicates downward	When Show slopes is selected, adds an arrow to indicate which side slopes down
Show vertex elevation	Toggles the display of all vertex elevations
Show profile line markers	Toggles the display of markers at the ends of the profile line
Add Profile	Adds a profile line for modifying the surface
Edit Profile	Enters editing mode for the selected profile, for Editing aligned hardscapes or modifiers with profile lines
Profile Line Marker Styles	Opens the Set Marker Style dialog box, to select the profile marker type at each end of the profile line; markers can be the same (Match beginning) or different (Differentiate) at each end of the section line
Delete Profile	Deletes the selected profile
Information
Update Calculations	Updates the area and volume calculations displayed in the Object Info palette for the area of the site model located under the site modifier (grade limits must exist around the modifier)
Site model area and volume data	Displays the area and volume information for the site model area located under the site modifier; select the units for the area and volume (grade limits must exist around the modifier). For more information, see Site model properties.
Vertex parameters	Edits the path vertices; see Editing vertex-based objects
Move	Select the vertex, and then edit its X/Y value
Edit	For vertex selection made in Move, scrolls through the vertices, highlighting the currently selected vertex. Click the center button to highlight the selected vertex.
