CONSTRUCT POSITION DIRECTION DISTANCE ANGLE LINE PLANE

The construction aids available in MODEL let the user display coordinates, directions, distances, angles and plane definitions.

The constructed quantities are written out into the REQUESTS region of your display. These quantities can be written into variables for later use. The commands used to define constructed quantities make use of p-points, p-lines, pins, directions, positions and orientations.

The different methods for constructing these entities are:

•

CONStruct Angle

position1 TO position2 TO position3
direction1 AND direction2
line1 line2
line plane
plane1 plane2
plane line

•

CONStruct DISTance

position1 TO position2
position TO line
position TO plane
line1 TO line2

projection of any of the above ALong a given direction

•

CONStruct Position

NEArest position ON line
NEArest position ON plane
INTersect plane1 plane2 plane3
INTersect line plane
INTersect line1 line2 (gives result on line1 if lines are skew or parallel) plane line

•

CONStruct DIRection

NORmal plane
ORTHogonal direction1 AND direction2
ORTHogonal direction AND line
ORTHogonal line1 AND line2
ORTHogonal line AND direction
position1 TO position2
plane
line

•

CONStruct LINe

JOIn position1 TO position2
direction THRough position
PARallel line THRough position
NORmal line THRough position
NORmal plane THRough position
PROJection line ON plane
INTersect plane1 plane2

•

CONStruct Plane

THRough position1 AND position2 AND position3
direction THRough position
direction THRough a p-point, pin or digitised point (optionally offset a given DISTance or relative to existing geometry: INFront or BEHind an element, p-point or position: FROm or TO a position)

Note:

In all of the above, position, direction, line or plane is defined in normal AVEVA E3D™ format, or by reference to a p-point, pin or marker, or picked from an appropriate view.


Examples:
Q CONS POS P2 OF FLAN 4 OF BRAN /PIPE1-1 TO PLANE PIN 7	The intersection between the specified point and the plane perpendicular to pin 7 is shown.
Q VAR 5 CONS POS PL TO LINE PA OF NEXT	The closest point on the line from PLEAVE to the intersection of the two lines is placed in Variable 5.
Q CONS POS PIN5 TO PLA PIN6	The intersection between the direction of pin 5 and the plane perpendicular to pin 6 is written out into the request region.
Q CONS DIR PL	The direction of the line is output in World coordinates into the request region.
Q CONS DIST PA TO PL	The dimension from the first to the second p-point of the current element is written out into the Request region.
Q VAR 5 CONS DIST PL TO LIN PA OF NEXT	The minimum distance between PLEAVE of the current element and the specified line will be placed in Variable 5
Q CONS ANG PIN1 TO PIN2 TO PIN3	The angle between the three specified points is written out into the Request region.
Q CONS ANGL PL LIN PA OF NEXT	The angle between the lines from the two specified p-points is written out into the request region.
Q CONS LINE JOIN P0 TO P1	Constructs a line joining the two p-points, displaying the line description in the request region.
Q CONS PLANE P3 DIST 900	The plane perpendicular to the specified point and 900 from it is written out into the request region.
Q CONS PLANE PL THROUGH /NOZZ5	The plane perpendicular to the specified point and intersecting /NOZZ5 is written out into the request region.
Q CONS PLANE PA DIST 500 BEH /COL19	A plane perpendicular to the specified point will be defined and written out into the request region. The plane will be positioned 500 to the far side of /COL19.
