Solibri Model Checker (SMC) includes the rule template named Space Group Containment (Rule Template # SOL/175) that is able to check that specific space groups exist in your model and that those space groups contain the correct spaces and counts of those spaces. Since the list of required space groups and their required spaces varies from project to project, you must configure the rule parameters with your own values rather than using default values, as with some other rules in SMC.
You are able to find information for this rule in the help topics by following the link below to the Solibri Solution Center:
The following article will provide an additional explanation, using the SMC Building.ifc and the “Example Rules” role. To open this role, select Roles under the File tab, click the Open button, and browse to the Example Rules role.
This role includes examples of all the rules templates in SMC.
After opening the SMC Buidling.ifc, switch to the Checking tab. When you click to add a ruleset, a window opens that allows you to select rules from the Example Rules role. Please, select the #175 Space Group Containment.
Click the checking button to view the results of the check.
The first category of results listed is “Not enough spaces”. This category occurs when a space group does not contain a required space. You can see in the Info view, the Elevator space is not included in the Common Area space group.
Checking the rule parameters of the rule, we see all the required space groups and what spaces are required to be contained in those space groups. Space Groups named Common Area must contain a single Elevator, Lobby, Stair, and Corridor space.
In the model, the Common Area space groups contain a single Lobby, Stair, and Corridor, but not the required Elevator space, which explains the result previously seen.
The second category of issues is listed as “Too many spaces.” These issues occur when a space group contains additional spaces that aren’t listed in the requirements. The Common Area 231 space group includes a Restroom, Gym, Kitchen, and two Corridors instead of a single Corridor, which explains the result and description in the Info view.
The last category of issues is “Inadequate Information.” These results are listing space groups that were not listed in the requirements. The requirements in the Rule only allow for space groups named Common Area, Education and Conference Area, Petty Education Inc., Arbor Doves, Inc., Tomorrows Lubrication, Inc. and Biochemical Startup, Inc..
Checking the Classification view, there are two types of Space Groups, Gross Area and Other. Only the space groups from the Other type are listed in the requirements of the rule.
These results of additional space groups have a low severity denoted by the yellow warning icon, so you could approve their results as non-issues or you’ll need to fill in all the required spaces and their counts for the Gross area on each floor. Alternatively, you could remove gross areas from the classification rules of the Space Grouping classification.
