Synopsis

PDX_MSGT s041_CreateVlPrDf(long option, MDA_PTR prdfsh_ptr, MDA_PTR rprcnt_ptr, MDA_PTR msbr_ptr, int property_type, char *property_name, char *property_description, int unit, void *values, int step_model, MDA_PTR *vlprdf_ptr)

Purpose

Create a STEP (part 41) validation property definition.

Description

This function supports attaching validation properties to both solids as well as shape representations. An example of a solid validation property is illustrated below:

.RS 3 .nf #362=REPRESENTATION('centroid',(#381),#161); #364=PROPERTY_DEFINITION('geometric_validation_property','centroid of cube',#366); #365=PROPERTY_DEFINITION_REPRESENTATION(#364,#362); #366=SHAPE_ASPECT('','solid associated with cube',#174,.F.); #367=SHAPE_REPRESENTATION('',(#150),#161); #368=SHAPE_DEFINITION_REPRESENTATION(#369,#367); #369=PROPERTY_DEFINITION('','shape for solid with which properties are associated',#366); #381=CARTESIAN_POINT('centre point',(2.0,2.0,2.0)); .fi .RE

An example of a validation property attached to a shape representation is illustrated below:

.RS 3 .nf #391=PROPERTY_DEFINITION('geometric_validation_property','volume of assembly',#177); #392=MEASURE_REPRESENTATION_ITEM('volume measure', VOLUME_MEASURE(76.566), #407); #397=REPRESENTATION('volume',(#392),#320); #399=PROPERTY_DEFINITION_REPRESENTATION(#391,#397); #407=DERIVED_UNIT((#408)); #408=DERIVED_UNIT_ELEMENT(#154,3); #409=NAME_ATTRIBUTE('CUBIC INCH',#407); .fi .RE
