Level 1: Creating Individual Design Objects
In the first level of the workflow you can set up the source drawing—the
drawing in which the object is created and stored—in one of two ways. You
can either create one object per drawing or you can include several objects in
a single drawing. Use the following sections to help you decide how to set up
your source drawing and how to manage drawings, survey data, and points.
One Object, One Drawing
In this scenario, you save each design object in its own drawing. If you know
that team members will have to share or edit an object at the same time, it is
recommended that you adopt the one object, one drawing approach. Autodesk
Vault controls data-sharing using the source drawing from which a design
object is created. If you place two or more design objects in the same source
drawing, only the user who has checked out the drawing from a vault can
edit the design objects. In effect, a drawing locks any design objects contained
in it, so that only the user who has checked it out can make changes. Therefore,
to allow multiple people to edit multiple design objects, you need to place
the objects in separate drawings. For example, if your project design has five
alignments and multiple team members need to edit these alignments
simultaneously, then you need to store each alignment in its own drawing.
By doing so, each team member with write access can edit the alignments as
needed, while other team members can still concurrently reference the
alignments for other design tasks.
The one object, one drawing approach allows you to continue to share objects
collaboratively among team members, like you may have done with Land
Desktop. The main difference is that with Land Desktop, anyone working on
a project can edit objects. With Civil 3D and Autodesk Vault, you can set roles
and permissions for individual users, defining what actions they can take. By
using the one object, one drawing approach in Civil 3D, as many people as
possible can work simultaneously on projects in a secure way. The extra time
it takes to create and name a new drawing for each new design object is
minimal—and you gain the ability to keep your project progressing quickly.
