Setting site model properties

● The site model object can be copied, cut, pasted, rotated, and deleted like other objects. In Top/Plan view, the 2D Display selected for the site model is shown; if both existing and proposed models are selected for display, they are superimposed. In any 3D view, the 3D Display selected (if any) is shown.

● The site model can be textured from the Render tab of the Object Info palette. The texture is applied to the surface of the site model, and is scaled to fit the site model bounding box.

● The site model surface can be sculpted, pushing and pulling the surface to create a custom site model as described in Sculpting the site model terrain.

● The site model contours can be edited, changing the original source data (the existing site model) or the proposed site model as described in Editing site model contours.

● Right-click on the site model and select Edit from the context menu, or select Modify > Edit Site Model. From the Choose Component dialog box, choose to edit the Site model settings or edit the existing or proposed contours.

● After generation, the site model is cached by default so that updating occurs more efficiently; however, large file sizes can result. See Document preferences: Display tab for information on changing the default setting.

● In addition to the Site Model Settings dialog box, you can change many parameters of a selected site model from the Object Info palette.

Parameter	Description
Geometry Lowest Z	Sets the lowest elevation (vertical Z offset) of the site model geometry; changing this value moves the entire site model, but does not affect site modifiers
Site Model Settings	Opens the Site model settings dialog box. The settings here (and the related graphic properties settings) are identical to those specified at site model creation. The option to keep or delete original source data is only available at site model creation.
Update	Updates the site model and any associated snapshots, when the existing site data has changed or site modifiers have been added or changed. Also, if the site model is textured with a geoimage, re-downloads the geoimage, when it no longer displays after a save operation.
Create a Snapshot	Click for Creating a site model snapshot with the current site model settings, for displaying different versions of the site model
2D Display	Select the display type for the 2D site model
2D Style	Select the display style for the 2D site model
3D Display	Select the display type (or no display) for the 3D site model
3D Style	Select the display style for the 3D site model
Area Display Type	Select the units for displaying the projected and surface areas for existing and proposed site models
Projected Area	Displays the projected area (the area projected in plan view) of the site model
Surface Area (Existing)	Displays the 3D surface area of the existing site model
Surface Area (Proposed)	Displays the 3D surface area of the proposed site model (when one exists)
Update Cut and Fill Calculations	Recalculates the site model cut and fill; after modifying and updating the proposed site model, click to view the resulting cut and fill volumes (see Creating a spoil pile area). When the calculated volumes indicate that updating is necessary, click to display the latest results.
Volume Display Type	Select the units for displaying the cut and fill volumes (or allows cut and fill volumes to be hidden, if desired)
Volume (Existing)	Displays the total volume of the existing site model
Volume (Proposed)	Displays the total volume of the proposed site model
Cut Volume	When the proposed site model has been modified by a site modifier, displays the volume cut from the site model
Fill Volume	When the proposed site model has been modified, displays the volume of fill added to the site model
Net C&F Volume	Displays the net cut or fill volume, indicating whether fill is required or extra cut volume needs to be removed from the site
Total C&F Volume	Displays the sum of the cut and fill volumes
Modifier Conflict Count	When site modifier conflicts prevent the site model from updating correctly, displays the number of conflicts in red; see Correcting site modifier conflicts
Show Modifier Conflicts	Select to display site modifier conflict icons on the drawing, or deselect to hide the icons
Edit Site Model Crop	Click for Cropping a site model with a custom site border
Edit Existing Site Model Surface	Click for Sculpting the site model terrain of the existing site model
Edit Existing Site Model Contours	Click for Editing site model contours of the existing site model
Edit Proposed Site Model Surface	Click for Sculpting the site model terrain of the proposed site model
Edit Proposed Site Model Contours	Click for Editing site model contours of the proposed site model
Recreate from Source Data	Restores the site model based on its source data or boundary, as described in the next section

Recreating the site model from the source data

The original source data, or boundary and grid-spaced loci, that were used to create the site model can be edited; this operation removes any edits to the site model contours or surface, and recreates the site model, but preserves any site modifier edits.

● Select the site model, and click Recreate from Source Data from the Object Info palette.

● Right-click on the site model and select Edit from the context menu, or select Modify > Edit Site Model. From the Choose Component dialog box, select Recreate from Source Data.

● Right-click on the site model and select Recreate from Source Data from the context menu.

2. In source data editing mode, changes can be made to the source data, and the source data can be validated (see Validating 3D source data).

3. Return to the site model by clicking Exit Recreate from Source Data at the top right of the drawing window. The site model updates automatically, reflecting any source data changes.
