Move four elements back from ce

SAME Go to the previous current element

NOTE: NEXT and PREV commands work on the list according to the modes

Forwards or Backwards. In backwards mode, the list is considered to be reversed so these commands have the effect of working from the opposite end of the list.

Query Commands

Q ATT Query all the attributes of the current element

Q POS Query the position of the current element

Q POS IN SITE (or Q POS WRT SITE) Query the position of the current

element relative to the site position

NOTE: Normally, the Q POS command gives the position relative to the element's

owner.

Q NAME Query the name of the current element. This may either begin with '/' character '/PIPING' or may be by a list position name (full name) such as: ELBO 2 OF /P1/B1

Q REF Query the database unique reference number

i.e. = 234/702. This is the best way of ensuring that you get to the element you want. Names can change but reference numbers are fixed so you always get the same element.

Positioning Commands (General)

At E300 N400 U500

At E3333 N6000 U50 WRT SITE At N500W30U600 WRT WORLD AT N400 U500 E300 IN ZONE At N40 WRT /FRED

Position an element explicitly at the coordinates given relative to the element's owner. To position relative to some other element, wrt can be added, as shown

BY N500 Move the element north from it's current position by 500mm (This is relative movement.)

CONN P1 TO P2 OF PREV Positions P1 at the specified point and orientates the element such that P1 is pointing in the opposite direction to the specified ppoint.

CONN IDP@ TO IDP@ Connect a picked Ppoint on the current primitive to a picked Ppoint of another

CONN P1 TO IDP@ Connect P1 of the current primitive to a picked Point of another primitive

Move syntax

Position>Move>Distance

Moves the element’s origin by a given distance in a given direction.

Ex. MOVE N DIST 10’ MOVE S WRT /* DIST 5' MOVE E IN SITE DIST 5' Position>Move>Through

Doc No: 9100-02-22-110-A4-Rev0 Page 160 of 165 Moves the origin of the element in a given direction through a Reference Plane Perpendicular to the line of travel that is passing through a picked element, p- Point, or coordinate.

Ex. MOVE N THRO ID@ MOVE N THRO IDP@ MOVE N THRO N46’

Position>Move>Clearance

Moves the element’s origin, p-point, or obstruction in a given direction with a clearance from another item’s origin, p-point, or obstruction.

Ex. MOVE E DIST 10’ FROM /P-101 MOVE E CLEARANCE 10’ FROM /P-101

The options INFRONT, BEHIND, ONTO, and UNDER refer to a picked or named item’s physical obstruction, while the TO and FROM options refer to the item’s origin. INFRONT and TO refer to the near side while BEHIND and FROM refer to the far side of an item.

Position>Plane Move>Through

Moves the origin of the element in a given direction through a Reference Plane Specified by the user that is passing through a picked element, p- point, or Coordinate.

Ex. MOVE ALONG E PLANE N45W THRO ID@

Positioning Commands (Piping)

NOTE: All the above commands can be used with piping components for exact

positioning. The following commands are specific to piping because they use the implied direction of the previous component to determine the position. This implied direction is some times referred to as the constrained centerline and is simply a line drawn in the direction of the previous component. All of the following commands will move components along this line.

DIST 300 Position the current element 300mm away from the previous component. The direction is taken as the leave direction of the previous component.

CLEAR 400 Position the current element with a clearance of 400m

Between it and the previous element. For most types of component, this command gives a tube spool length equal to the clearance value. For some components such as level operated valves the clearance is likely to take the lever length

Doc No: 9100-02-22-110-A4-Rev0 Page 161 of 165 as the obstruction length of the valve, so in this case the clearance might be more unpredictable.

THRO N500 Position the origin of the CE along constrained centerline through N500 in ZONE coordinates.

TO N500

THRO PT Position the origin of the CE along constrained centerline at the point where it intersects a perpendicular plane positioned at the branch tail.

CONNect Position the arrive point at the leave point of the previous Component and orientate the component to suit.

Orientation Commands (General)

ORI Y IS N AND Z IS U This is the default orientation (wrt owner) for all

Elements that have an orientation attribute.

ORI Y IS E45N Specify that the Y axis is pointing E45N. When only One axis is specified, the other tries to get to it's default, so in this case, Z will default to UP.

ORI P1 IS N Rather than specifying an axis, this command

Specifies that a particular ppoint is to be orientated in the direction specified.

ORI This command orientates the arrive of the element in the opposite direction to the leave of the previous element. It does not change the position.

CONNECT Perform an ORI, then position the arrive at the leave of previous.

DIR S This is a special command which is allowed to change the angle of a component. It first performs

Doc No: 9100-02-22-110-A4-Rev0 Page 162 of 165 an ori, then adjusts the angle to ensure that the leave direction is in the direction specified.

ORI AND P3 IS U Used for valves, tees, etc., this command performs an ori and then points the ppoint in the required direction. It does not change the angle.

DIR AND P3 IS U This is another special command which is only used on tees with variable angles. (Usually for sloping lines.) In this case, the tee is orientated and the angle adjusted to allow p3 to point in the direction specified.

Creating Elements

NEW BOX To create anything in PDMS, you need to be at the Right level in the hierarchy and use the command NEW followed by the TYPE of element you want to create.

NEW EQUI /T-1101 Create EQUI element and set the name attribute

NEW ELBO CHOOSE For piping components, you need to create the

Element and then link it to the catalogue via the spref attribute. The CHOOSE command allows you to select components from the specification by picking them from a displayed menu.

CHOOSE ALL Allows you to see more detail about the component Than CHOOSE on it's own..

Deleting Elements

DELETE ELBO To delete an element, the syntax is DELETE followed by the TYPE of element you are deleting.

DELETE BRAN MEM This deletes the members of an element (i.e. BRAN in this example) without deleting the element itself.
