SWE002 - Same number of points and edges for consecutive IfcSectionedSolidHorizontal section profiles

[RickBrice]

@aothms @civilx64

The informal propositions for IfcSectionedSolidHorizontal says:

2. If the type of sections is not IfcParameterizedProfileDef (i.e. an arbitrary profile), then the number of points and edges should be the same for two consecutive profiles

The attached file has bridge beams with tapered end blocks where a different number of points are used to define an IfcPolyline for consecutive cross section profiles. This file passes the validation service without error.

Since the informal proposition says "should" instead of "shall", maybe this is ok. Just thought I'd bring it up.

Hi @RickBrice coincedently we were just discussing this exact rule among others. Simple fact is that most of the informal propositions in the schema are not implemented yet, including this one.

@evandroAlfieri I believe this issue corresponds to Functional Part SWE for swept geometry. We can update the title to SWE001 if you agree.

Agree @civilx64
And I also did the followings:

• rename the rule in our spreadsheet
• rename this issue
• add a ticket to Jira
• assign other functional part tags: GEM, SWE, CPD

NOTE: CPD is a new one, suggested by @aothms, for clipped representation. With its introduction, IfcSectionedSolidHorizontal inherits this tag too. As...

This entity represents a solid that is defined by a series of cross-sections along a horizontal path. It can be used to create clipped representations by specifying different cross-sectional shapes at various intervals along a path.
