To change model properties

Open the Model Properties dialog box to change model settings. You cannot change the model database coordinate system after initial set-up.

1. Open the desired model.
2. Click .
3. In the Model Properties dialog box, set the following:
   • Name — The name that is assigned to the model database file and data folder.
   • Description — Displayed with the properties of the open model.
   • Coordinate Systems — You cannot change the model database coordinate system after creating a model. If necessary, change the UCS coordinate system, which determines the coordinates displayed in the status bar. The UCS does not affect how model data is stored or displayed.
   • Extents — By default, the model extent matches the database coordinate system. To define a smaller area (which saves space and improves performance), deselect Use Entire Model. Define the model extents interactively by drawing a bounding box or polygon in the model itself, or specify the X, Y extent coordinates.
   • Terrain — Set the default style for terrain in this model. Click the browse button and open the Land Cover folder to select a style.

     The default terrain style affects only areas where no specific coverage or terrain texture is applied. If an applied coverage or terrain is transparent, the default terrain does not appear underneath. However, if you delete a coverage or terrain texture, the default terrain material will be applied.

     Note: When you change the default terrain material, the entire terrain surface is regenerated.
   • Set Model Time — Displays only the assets whose creation and termination date range indicates that they exist during the specified time. To display all assets, regardless of their creation/termination dates, leave Use Model Time unselected.
   • Road Design Standards — Defines the horizontal and vertical geometric elements of design roads in your model. You can also specify the default driving direction of design roads in your model (left or right side of the road).

     Design roads can be viewed but not edited by users who do not have a subscription to Roadway Design for InfraWorks 360. See To set road design standards for more information.
