Glossary

Feature

Point, P-point, line or P-line on the 3D model that can be used for alignment.

Graphical Selection

One or more elements selected for subsequent manipulation using the Locator Handle.

Selection Set

When in Navigate mode, the elements selected by a pointer click. For an Equipment, all the constituent primitives will be selected, for a piping Component, all connected Components will be selected.

Linear Movement Handle

A handle situated on the Locator Handle, which when selected for a drag operation, constrains movement of the selection to be along the direction of the selected major axis.

Locator Handle

A collection of handles which together provide a mechanism for positioning and orientation of selected elements.

Movement Increment

The incremental step in current distance units that a selection will move in the direction of a major axis of the Locator Handle when a planar movement handle or a linear movement handle is dragged.

Movement Axis

The axis identified by the Linear Movement Handle. During a drag operation, the current selection will be constrained to move in the direction of the movement axis only, while following the movement of the pointer.

Movement Plane

The plane identified by the Planar Movement Handle. During a drag operation, the current selection will be constrained to move in the Movement Plane only, while following the movement of the pointer.

Planar Movement Handle

A handle situated on the Locator Handle, which when selected for a drag operation constrains movement of the selection to be in the plane indicated by the Planar Movement Handle. That is, the XY, XZ or YZ plane of the Locator Handle.

Rotation Increment

Incremental step in degrees that a selection will rotate when a Locator rotation handle is dragged.

Reference Point

Position used as a datum point for subsequent movement of the Graphical Selection.

Plant Item

A Design database element that represents an engineering item that can be individually selected and manipulated to modify Plant layout. For example, Equipment, Steel Section, Piping Component.

Ship Item

A Design database element that represents an engineering item that can be individually selected and manipulated to modify Ship layout. For example, Equipment, Steel Section, Piping Component.
