19 ---Purpose : Provides tools to exploit and edit a set of STEP data :
20 -- editors, selections ..
22 uses Standard, TCollection,
23 Interface, IFSelect, StepData
28 -- This class is for global context : ApplicationContext,
29 -- ProductRelatedProductCategory
32 -- This class allows to edit product data for a SDR
35 -- Some useful operators
36 -- They are not classes, they are just based on general tools
38 Protocol returns Protocol from Interface;
39 ---Purpose : Returns a Protocol fit for STEP (creates the first time)
41 NewModel returns StepModel from StepData;
42 ---Purpose : Returns a new empty StepModel fit for STEP
43 -- i.e. with its header determined from Protocol
45 SignType returns Signature from IFSelect;
46 ---Purpose : Returns a SignType fit for STEP (creates the first time)
48 NewSelectSDR returns SelectSignature from IFSelect;
49 ---Purpose : Creates a Selection for ShapeDefinitionRepresentation
50 -- By default searches among root entities
52 NewSelectPlacedItem returns SelectSignature from IFSelect;
53 ---Purpose : Creates a Selection for Placed Items, i.e. MappedItem or
54 -- ContextDependentShapeRepresentation, which itself refers to a
55 -- RepresentationRelationship with possible subtypes (Shape...
56 -- and/or ...WithTransformation)
57 -- By default in the whole StepModel
59 NewSelectShapeRepr returns SelectSignature from IFSelect;
60 ---Purpose : Creates a Selection for ShapeRepresentation and its sub-types,
61 -- plus ContextDependentShapeRepresentation (which is not a
62 -- sub-type of ShapeRepresentation)
63 -- By default in the whole StepModel
