Catalogue Database Elements Setup in PARAGON : 3D Geomsets (GMSET)
3D Geomsets (GMSET)
A GMSET is a grouping of 3D primitive elements which are used to make up Piping Components, Joints and Fittings. It specifies the dimensions, orientation and obstruction geometry of each primitive. The Geomset defines the symbol that is drawn for a particular Component by PARAGON (and MODEL) and also defines the obstruction geometry of the Component for use when checking for clashes. Each symbol is built up from a combination of the following primitives:
•
SBOX - rectangular box
•
BOXI - boxing (used by HVAC and Ducting etc)
•
SCON - cone
•
LCYL - cylinder
•
SCYL - cylinder
•
SSLC - slope bottomed cylinder
•
SDIS - disc
•
SDSH - dish
•
SLINE - line
•
LINE - line
•
LPYR - pyramid
•
SCTO - circular torus
•
SRTO - rectangular torus
•
LSNO - snout
•
SSPH - sphere
•
TUBE - tubing
•
SEXT - user-defined extrusion
•
SREV - solid of revolution
GMSET has no attributes other than the standard ones. Each member element of a 3D Geomset has the following attributes in addition to the standard ones:
•
LEVEL - the drawing level range attribute
•
CLFLA - the centreline drawing flag attribute
•
TUFLA - the tube drawing flag attribute
•
OBST - the obstruction attribute
•
DESC - a textual description of the Geomset
•
GTYP - the generic type of the item for which the Geomset is used
•
PURP - the purpose of the Geomset
The settings of LEVEL, CLFLA and TUFLA affect whether the primitive is drawn or not by PARAGON (or MODEL), as they do for P-lines. See Structural Pointsets (PTSSET) for details.
OBST is a number which defines the obstruction level of the primitive for use by MODEL’s clash checking facility:
•
OBST = 0:
No obstruction. The primitive will not clash with anything (used for symbols and negative volumes).
•
OBST = 1:
‘Soft’ obstruction. Used for insulation, access volumes, penalty volumes, etc.
•
OBST = 2:
‘Hard’ obstruction. MODEL’s clash checking facility will report hard interference with any item having OBST 1 or 2.
The LEVEL, OBST, CLFLA and TUFLA attributes are common to all primitives. Each primitive also has additional attributes depending on its shape; these are described in the next section.
