Library Browser
• Each “file” icon is a DGN
• Each DGN contains one or more library items
• Properties are read only – for information
• Preview shows the selected roundabout or approach
• Remember – the browser is only used to place an item!! Preview

Changing the geometry
• Two ways to do this:• Properties and Manipulators

Entry path radius
• Design Speed Calculation
• Additional design check
select entry path curve

The Message Center
• Message Types
• Errors - Design problems. eg, an item cannot be created.
• Warnings- Design warnings. eg, a geometry value is outside recommended limits.
• Messages- Information Messages. eg, a property value has been changed when geometry has been adjusted.

Relationship between design and analysis• We now need to resolve the warnings in the
Message center• Modifications to the design will automatically
update the entry path analysis

Commit
• Creates features in the native application• Method varies according to the native application• In InRoads geometry is created in the ALG file• In PowerCivil and GEOPAK there is no Commit
option – you import the elements you require to the Site Modeler
