PDS TUTORIALS: Basic Sketching

.

In this section you will learn to sketch centerline routing, to set and change the active parameter data, to revise piping segments, and to populate the centerlines with graphic components.

Review Nozzle Data

Review Nozzle Data reviews the attribute values for all the nozzles associated with a specified equipment item. Select Revise Component from the Piping pull-down menu.

Pds Sketch

Sketch defines the centerline geometry for a pipeline and defines the attributes of the piping segment. Select Placement from the Piping pull-down menu.

PDS Move Vertex

Move Vertex moves an identified segment vertex to a new location. You can move the vertex to any location by keying in delta distances, absolute distances, or a distance and direction, or by relocating an end point connected to a nozzle to the current nozzle location. Select Revise Segment from the Piping pull-down menu.

PDS Delete Vertex

Delete Vertex deletes a vertex from a piping segment and redraws the piping segment to reflect the deleted vertex. Select Revise Segment from the Piping pull-down menu.

PDS Insert Vertex

Insert Vertex inserts a vertex in a specified segment pipe run. The new vertex is inserted in the pipeline following the vertex used to identify the pipeline. Select Revise Segment from the Piping pull-down menu.

PDS Attribute Break

Attribute Break creates an attribute break at a point on an existing pipe segment. Use this command for a change in size, spec, fluid code, or any of the active segment data. Select Revise Data from the Piping pull-down menu.

PDS Connect Segments

Connect Segments combines two piping segments that have concident endpoints. Select Revise Data from the Piping pull-down menu.

PDS Data Button

Revise Segment Data edits the attribute data for all existing pipe segments in a pipeline in one operation. Select Revise Data from the Piping pull-down menu. Do NOT revise the NPD if there are any other size changes or reducers on a pipeline.

PDS Attribute Button

Revise Attributes modifies the database attributes or user data associated with a selected element. Select Revise Data from the Piping pull-down menu.

PDS Auto Placement

Automated Placement automatically places piping commodity items on existing piping segments. The software recognizes piping which already exists on the segments. Select Placement from the Piping pull-down menu.

PDS Delete Piping

Delete Piping deletes piping components and segments from the active model. Select Revise Group from the Piping pull-down menu.

PDS Delete Componenet

Delete Component deletes a single component, pipe, or segment from an existing pipeline. Select Revise Component from the Piping pull-down menu.
