Dimension Skewed Pipe in Isometric Views

Dimensions on skewed Pipe in isometric views can have misleading graphics. To avoid this, constructed Dimension Point can be used, whose position is defined by a RULE set which gets one coordinate of position from one Component and the remainder from another. The constructed Dimension Point can then be used with either Component to draw Dimensions with sensible graphics.
For example, an elevation Dimension is required between a Valve and an Elbow in skewed pipe. Sensible graphics can be achieved by:
|
NEW LDIM |
|||
|
DIMFROM valve_id |
|||
|
NEW DPOI |
|||
|
RULE SET POS |
(E (POS(1) OF <valve_id> WRT /* ) $ |
||
|
(N (POS(2) OF <valve_id> WRT /* ) $ |
|||
|
(U (POS(3) OF <elbow_id> WRT /* ) |
|||
|
RULE EXEC POS |
|||
A copy of this Dimension Point can be used in other Dimensions to dimension between the Elbow and the Easting/Northing of the Valve.
The creation of rule sets is an administrative task. Refer to Representation for further information.
