Candidate database entities are those that are visible unless target database entities are selected within the Project command. The candidate
database entities for projection can be modified by changing the Show/Hide status of the entity (see
the Attributes section for more detils) or by turning database layers on or off (see
the List section for more details). Only surface and quilt entities in database layers that are
on and are set to Show can be projected onto. Turning off the layer containing the entities that the grid points should not be projected onto, or changing the
entity’s display status to Hidden, has two effects. First, it prevents the projection algorithm from placing the grid points on the wrong
surface. Second, it reduces the number of surfaces the projection algorithm has to go through and, therefore, the process will run a little faster.
Tip: For complex geometries, select your target database surfaces within the Project panel before using a Closest
Point projection. Alternatively, you can also isolate the layer containing the database surfaces onto which you plan to closest point
project. Either one of these methods will help ensure that all the points in the selected grid entity are projected onto the appropriate surfaces.
Select Edit, Project. Select the Type of projection, the Direction of the projection (if applicable), and whether the Interior
Only or end points as well should be projected in the Projection Control frame. If a specific database or set of database entities are the
target, select them in the Target Database Selection frame. Click Project. If the projection is not satisfactory, change the projection
settings, then click Project again. The projected entity will be re-projected based on the new settings. Clicking OK will save the projected
entity, while clicking Cancel will exit the Project panel without saving any changes.
The Project panel provides multiple options for projecting an entity in addition to a summary of projection statistics.
Within the Project panel, the Projection Summary table provides details about the points and percentage of points that have been projected
on the connector and/or domain levels or provides a percentage only for database curve projections.
- Points On: Refers to the number of points in selected grid entities that are on a database entity.
- Points Off: Refers to the number of points in selected grid entities that are off of a database entity.
- Percent On: Refers to the percentage of points in selected grid entities that are on a database entity. For database curves this represents
the total portion of the curve on the target database.
- Percent Off: refers to the percentage of points in selected grid entities that are off of a database entity. For database curves this
represents the total portion of the curve off the target database.
Beneath the Projection Summary table, you will find the Project command which will apply any settings you have made in Projection
Control to either the entire visible database or those entities selected via the Target Database Selection command.
