Rules are available in Solibri Advanced and Premium, with full editing access.

Rules can be viewed in read-only mode in Solibri Starter and Essential if they are already present in the SMC File.
This article describes how the Free Floor Space rule works and how you can configure the rule.
The article covers the following topics:
This rule can be used to check different accessibility-related requirements for free space. For example, the rule can be configured to check that a corridor has unobstructed width of 1.2 meters or that a washroom has room for a 1.5-meter wheelchair turning circle.
The rule analyses spaces and the furniture placed in them and then searches for free floor areas that fulfil the configured requirements. It uses a space classification for grouping spaces by usage and a furniture classification for identifying the furniture that affects the free floor space. For each row in the Free Floor Space Requirements table, the rule looks at the selected space classification and checks all requirements defined for that row against the actual geometry in the model. If the free space that can be found in a space does not satisfy one or more of the requirements, the rule creates an issue.
In v9.13.5 and later, you can select to use classifications or filters for selecting exits and stairs. In earlier versions, you can only use classifications.
If you use classifications:
-
Space classification: Classification used for classifying spaces. Space Classification names are set in the Space Classification Name column in the Free Floor Space Requirements table.
-
Furniture classification:Classification is used to classify the furniture. Furniture Classification names are set in the Choose Requirements panel in the Furniture Distance and Free Space on Side sections in the Furniture Classification parameter, which can be accessed through the Requirements column in the Free Floor Space Requirements.
-
Free Floor Space Requirements: This table lists the different free floor space requirements. The table has two columns: Space Classification and Requirements. The Space Classification column indicates the types of spaces to which the requirements in the same row apply. The Requirements column has one or more requirements for the spaces.
The requirements are configured in a dialog where you can select which requirements apply to a given space classification and the parameters of each requirement. The possible requirements are:
If you use filters:
-
Spaces:
-
Furniture:
Requirements
More specific requirements can be configured in different places depending on which method you're using. If you're using classifications, click the Requirement cell in the table, and a dialog opens. If you're using filters, the requirements can be configured below the filters. You can select from the following options:
-
Free Wheelchair Turning Circle: When checked, the rule checks that a space has a free space for a circle of a given diameter.
-
Free Corridor: When checked, the rule checks that a space has a free corridor of the given width.
-
Subtract Door Swings: When checked, the swing measurement of the door is subtracted from the area.
-
-
Free Rectangle: When checked, the rule checks that a space has a free space for a rectangle of given dimensions.
-
Avoid obstacles: When checked, the rule checks that the rectangle fits the space without intersecting obstacles in the space.
-
-
Free Space on Side: This requirement can be used to check that the long side of a minimum bounding rectangle has free space of given length and width. The length of the requirement is measured along the long side of the furniture, and the width is perpendicular to that. The length can be either fixed or free. A free length equals to the dimension of the furniture long side. Typical use cases for this requirement are: free space next to a toilet seat, and free space next to bed.

Furniture Distance: You can specify here the furniture classification, minimum distance and maximum distance between the furniture. When the double-sided checkbox is selected, there needs to be a wall within the given minimum and maximum value of both sides, otherwise only on one side.
The rule uses three-level categorization in results. The main level category is the classification of the spaces that the door connects. The second category level is the type of the issue. The third category level is the type of spaces. The rule creates following types of issues:
-
No Free Floor for Wheelchair Turning Space ø 1.5 m
-
No Free Floor for a 3.0 m Wide Corridor
-
No Free Floor Next to Bed
