Obtaining Site Model Data

Site Model Section

Use the Site Model Section command to create a profile or sectional views of the site.

To create a site model section:

1.	Draw or select a 2D polygon or polyline to define the section alignment. In Landmark, if selecting a previously drawn polyline with station points, a station point profile can be created.

The polygon or polyline vertices must be contained within the limits of the site model.

2.	With the polygon or polyline selected, click Landmark > Site Model Section (Landmark workspace) or AEC > Terrain > Site Model Section (Architect workspace).

The Create Site Model Section dialog box opens. Specify the site model section parameters.

 

Parameter	Description
Create section on layer	Specify the layer where the section will be placed or click New Layer to create a new layer for the section
Draw Background Grid	Select to draw a background grid, and click the color box to specify the grid color
Draw Existing Site Profile	Select to draw a profile for the existing site model, and click the color box to specify the profile color
Draw Proposed Site Profile	Select to draw a profile for the proposed site model, and click the color box to specify the profile color
Draw Selected Station Profile (Landmark required)	Select to draw a profile of the station points, and click the color box to specify the profile color; this option is available only if a polyline associated with station points is selected
Station Points
Draw points at polygon vertices	If the selected polygon does not contain stake objects, select to create station points at the polygon vertices; this option is available only if a station polyline is selected
Draw points at interval	If the selected polygon does not contain stake objects, select to create station points at the specified interval
Draw points at existing stakes (Landmark required)	When stakes exist along the profile polygon, station points are automatically created for the stakes; this option is available only if a polyline with station points is selected
Formatting	Click to specify the section graphic formatting

3.	Click Formatting.

The Site Model Section Formatting dialog box opens. Specify the formatting for the site model section graphic.

 

Parameter	Description
Display Scale Factor	Specifies the site model scale factor; the layer scale factor is entered by default
Vertical Magnification Factor	Sets an independent scale factor for the Y axis of the graphic
Vertical Margin	Specifies the distance, in page units, between the highest and lowest points in the graph and the graph margins
Horizontal Margin	Specifies the distance, in page units, between the graph start and end and the graph margins
Draw Legend Text	Indicates whether to create a legend for the graph; legend text is color coded to match the section profiles
Legend point size	Specifies the size, in points, of the legend text
Draw Elevations	Indicates whether to display the elevation of the profiles along the station points
Elevation point size	Specifies the size, in points, of the elevation text
Station Point Labels (Landmark required)	Sets the type of label, if any, to apply to the station points on the background grid
Profile Line Weight	Specifies the thickness of the profile lines
Station Line Weight	Specifies the thickness of the station lines

4.	Click OK to return to the Create Site Model Section dialog box.

5.	Click OK to create the sectional view of the site. If the site model changes, the site model section needs to be recreated.
