Component Design

Assuming that you have opened a suitable 3D view, the interactive graphical Component design process in Paragon is initiated using the MODEL command.

If a new Component is to be designed, then a new Catalog element must first be specified by a command such as

The command

MODEL CE

(for ‘Model Current Element’) will add the new component to the 3D view.

Note:
The MODEL CE command is valid only for SCOM, SPRF, JOIN, and SFIT elements.

Only complete Components may be displayed in this way - individual Pointsets and Geomsets may not be, although these items will easily be distinguishable. (Geomset and/or Pointset elements can be removed from the display with the aid of the REPRESENTATION command - refer to P-point and P-line Representation).

The MODEL SETTINGS command can be used to specify the Component Design Data attributes. For example,

MODEL SETTINGS DDRADIUS 75 DDHEIGHT 200

gives the Design Data attributes DDRADIUS and DDHEIGHT values of 75mm and 200mm respectively. The DDRADIUS, DDHEIGHT and DDANGLE attributes are the Design parameters used in the selection process for variable Components. In PARAGON it is possible to use these attributes as part of the Component design. For example, whereas an attribute such as PHEIGHT would normally be defined in terms of parameters, a command such as:

PHEI DDHEIGHT

(assuming a suitable current element) would set PHEIGHT to the Design height. (In such a case, a MODEL SETTINGS command would need to be followed by a MODEL CE command before any change in the display would be observed.)

To produce a display of a Component with insulation, the bore, temperature and working pressure of the Component must be known. To this end the MODEL SETTINGS command can be used to set the BORE, TEMP and PRESSURE. This must be done before the Insulation Specification, INSPEC, can be specified. For example,

MODEL SETTINGS TEMP 300 BORE 80

would set the temperature and bore Design Data attributes (the pressure would stay at its default value). The Insulation Spec may then be specified by a command such as

MODEL SETTINGS INSPEC /INSUL1

Assuming the drawing REPRESENTATION (refer to Reference Section) is correctly set, the Component will then be displayed with insulation shown.

All Design settings can be restored to their defaults by

MODEL SETTINGS DEFAULT

Note:
This command also deletes all default and specimen values of parameters. It unsets the Insulation Specification.

The default values of the Design Data attributes, and the full syntax of how to set them, are given in Reference Section.

QUERY MODEL SETTINGS will output the Design settings currently in use. The Design process is turned off by

MODEL END

which also has the effect of clearing the display.
