Use sites to collect or group collections (parcels, alignments, gradings, and feature lines) by a topology that they have in common.
Examples of sites include soil maps, watersheds, or subdivisions. Sites can geographically overlay each other as is shown in the following illustration, while remaining independent. For example, a soils map and a subdivision with roads and lots can overlay each other, but remain independent of each other. Therefore, a parcel in a soils site would never be affected by an alignment in a subdivision site, even if their extents overlap.
All objects in a site topology collection share a common topology and have relationships to each other.
When you create parcels and gradings, you specify a site for them. If you create these objects before explicitly creating a site, a default site named Site 1 is created for them.
When you create an alignment, you may either accept the default <none> site selection, place the alignment on an existing site, or create a new site. When an alignment is placed on a site, it will create parcels if it forms closed regions and subdivide existing parcels on the site if it crosses through them. Accepting the <none> site selection places the alignment in the top-level Alignments collection, which prevents it from forming or interacting with parcels or any other objects. See Alignment and Site Interaction for more information.
Topics in this section
- Sites Collection
Use the Prospector tree to access the Sites collection, which can contain one or more site topology collections.
- Site Topology Collection
Use the named site topology collection (for example, Site 1) under Sites in the Prospector tree to edit or list the properties of a particular site, including its name, description, and 3D geometry.
- Alignment and Site Interaction
When alignments are placed on a site, they will interact with other objects on the site.
