Align the selected rooms' vertices to the selected lines/polylines if the room vertices lie within the specified Alignment Distance.
Options
Distance
The maximum distance between a room vertex and the line or polyline at which point the vertex will be aligned to the line
Snap Vertices
Select to snap the room vertices to the line/polyline vertices after the initial alignment operation is complete
Constrain Edges
Select to have all axes of the room edges that were not pulled to the line geometry be preserved
Using the Snap Vertices option will perform an additional operation that snaps the vertices to line/polyline vertices after the initial alignment operation is complete.
This command is primarily used for fixing misalignments between rooms, which are common in raw exports from Revit. It is also useful for adjusting the exterior boundary around entire stories, enabling you to align rooms to the inside or outside wall finish instead of using the wall centerline as is typical when exporting Revit rooms. See the Create Boundary command for more information.
This command is only visible when at least one room and one alignment line/polyline are selected.
Automatically align selected rooms to common axes identified across them. The command is intended to automatically perform most of the alignments that would typically be done manually. Note that having a line selected while running this command will force the generated alignment axes to be generated only in the plane of that line.
Options
Distance
The distance with which room vertices will be aligned to common axes. No vertex in the input rooms will be moved more than this distance
Exclude Angle
A positive number in degrees for the maximum difference that a geometry segment can differ from the alignment axes for it to be ignored/excluded from alignment
Story-by-Story
Select to have this command run with each story individually rather than all stories of the model together. Running story-by-story tends to produce a more controlled and result with fewer unintended alignments happening. This is useful when the model is large and rooms between stories do not have a strong relation to one another.
Axes Only
Select to have this command only output the common axes of the selected rooms into the scene and not perform any auto-alignment of rooms with these axes. This can give more control over which axes are or are not used by allowing manual selection and aligning with desired axes
Join coplanar walls of the room, effectively removing colinear vertices from the room polygon. Use this command to simplify the geometry and clean up the model before running 'solve adjacency' or 'alignment' commands.
Pull the vertices of one or more rooms to the first 'target' room in the selection. The operation of pulling can be thought of as aligning the rooms to the target room's segments and then snapping to its vertices.
Options
Pull Distance
The maximum distance between a room vertex and the target room edges at which point the vertex will be pulled to the target room
Coordinate Vertices
Select to further coordinate the vertices after the initial pulling operation is complete. Coordination means that any vertices of the target room that lie within the specified distance to a pulled room but were NOT matched to a vertex on that room will be inserted into the pulled room
Constrain Edges
Select to have all axes of the room edges that were not pulled to the adjacent room be preserved
Invert Selection
Select to have the command pull the first room in the selection to all other rooms in the selection. This is the inverse of the default behavior, which uses the first room in the selection as a target and then pulls all following rooms to it
Using the Coordinate Vertices option will run an additional operation to adjust the number of vertices in the rooms that were pulled. This can result in better matching of segments between the rooms like so:
Remove the holes inside the room that are smaller than a certain specified Area Threshold. Use this command to remove column and duct holes from inside rooms.
Options
Area Threshold
The maximum area for a hole below which it will be removed
Remove the segments of the room polygon that are smaller than a certain specified Segment Distance. Use this command to remove column holes and other unwanted small segments at the edges of the rooms.
Options
Segment Distance
The maximum length of a segment below which it will be removed
Simplify and reduce the number of vertices defining curved edges of rooms.
Options
Deviation Distance
The distance that a curved part of the room is allowed to differ from a straight line. Lower tolerance values correspond to a higher resolution of curvature with more vertices
Snap the selected rooms to a cartesian grid defined by a Grid Increment distance, which sets the resolution of the grid. This command is useful for IES VE modelers who need geometry on a grid for ease of edit-ability.
Options
Grid Increment
A positive number for dimension of each grid cell. This should be less than the smallest detail to resolve on the rooms. NOTE that this value can be different from the grid size in the preview
Exclude Angle
A positive number in degrees for the maximum difference that a geometry segment can differ from the grid for it to be ignored/excluded from snapping. Setting the exclude angle to zero will guarantee that all geometry is snapped to the grid. However, this may produce jagged geometries, particularly when there are parts of a geometry that are not intended to be aligned with a grid
Subtract one room from another room. Useful for resolving colliding room geometries.
The first room of the selection is the room to be subtracted from and all following rooms in the selection will be used for subtraction.
Offset all windows and/or skylights by a certain distance. This is useful for translating between interfaces that expect the window frame to be included within or excluded from the geometry.
Options
Offset Distance
Offset all windows and/or skylights by a certain distance. This is useful for translating between interfaces that expect the window frame to be included within or excluded from the geometry
Ignore Windows
Select to have the windows left as they are during the offset operation
Ignore Skylights
Select to have the skylights left as they are during the offset operation
Fix the windows of the rooms by merging the colliding windows and trimming those that extend past the parent Face. The Rectangle option can be used to further simplify non-rectangular windows into rectangular shapes
Options
Parent Edge Offset
A number for the distance from the parent face edges to which windows will be trimmed. Entering a non-zero number here can ensure that space is left on parent faces to account for window frames
Small Area Threshold
The maximum area of a window below which it will be removed. Set to zero to keep all windows no matter their size or their validity.
Rectangle
Select to have overlapping window geometries resolved by replacing them with a boundary rectangle around the overlapped group instead of boolean unioning the overlapped geometries. Useful in cases where a dozen or more geometries overlap with one another such that the unioned result is not as clean or desirable as a bounding rectangle
This command is intended to fix such issues while being faithful to the original window geometry. It trims windows that extend past their parent face and merges overlapping windows by either boolean-unioning them or replacing them with a rectangle around the group (if the Rectangle option is selected).
For intentionally simplifying the window geometry for either simulation speed or overall model cleanliness, see the "Simplify windows" command.
Simplify the windows and skylights of a room for either simulation speed or overall model cleanliness.
Options
Merge Distance
The maximum distance between rooms at which point they will be merged together. Setting a non-zero value here will allow you to merge rooms that have gaps in between them (crossing gaps up to the specified distance). This option is particularly useful for IDA-ICE users who must work with rooms that are exported at the interior wall finish
Single Window
Select to have the windows simplified to a single window within the center of each wall, which matches the overall area of the original windows
Delete Interior
Select to have the interior windows removed from the rooms, which can increase simulation speed in several BEM platforms
Ignore Skylights
Select to have the windows left exactly as they are during the process of simplifying skylights
Ignore Windows
A boolean to note if the windows should be ignored during the process of simplifying the windows
Note that this command is not intended to fix invalid or un-simulate-able windows and the "Repair windows" command should be used for these purposes.
Fill holes and gaps across the selected rooms with new rooms (or existing rooms that are adjacent to each hole).
Options
Area Threshold
The area below which a hole gets merged into adjacent rooms and above which it will be filled with a new room. To fill all holes with new rooms, set the area threshold to zero. To have all holes merged into neighboring rooms, set the area threshold to a high number
New Room Name
Text to set the name of newly-generated rooms. In the case of multiple holes being filled, this input will be a base name and an integer will be automatically added to the end of each new room name
Merge small rooms in the selection into the larger adjacent rooms. Small rooms are always merged into the adjacent large room with which they share the most perimeter.
Options
Area Threshold
The floor area below which rooms are considered small and should be merged into larger rooms of the selection.
Merge several rooms into a single room. Setting a Merge Distance that is larger than 0 will allow you to merge rooms that have gaps in between them - crossing gaps up to the specified distance.
Options
Merge Distance
The maximum distance between the rooms in which the rooms should be merged.
Simplify Windows
Select to have the windows simplified when merging rooms.
Join Faces
Select to have the coplanar walls should joined together when merging rooms.
Useful for cases where multiple rooms in a Revit model should be represented as a single zone in the energy model.
Split rooms or roofs by the selected lines/polylines.
Create core and perimeter rooms for a selected room. This is particularly useful for creating models according to typical zoning practices, where each façade orientation is a separate zone.
Options
Offset Distance
The distance that the perimeter of the rooms will be offset
Air Boundary
Select to have the new separation walls between the core and perimeter rooms set to Air Boundary
The perimeter rooms will have a depth equal to the specified Offset Distance and the Air Boundary option lets you optionally set the boundaries between the core and perimeter rooms to an air boundary if the room being split represents an open space. It is recommended that the "Join coplanar faces" command be run before using this command.
Split the selected rooms vertically if they are tall enough to cross multiple stories in the model.
Set the adjacencies between the selected rooms to use air boundaries. Note that adjacencies should be solved between rooms before running this method in order for it to have any effect. If lines are selected while running this command, they will be used to set air boundaries for only the adjacencies that are coincident with those lines.
Solve adjacency between selected rooms by assigning interior boundary conditions where rooms touch one another.
Options
Ceiling Adjacencies
Select to have the adjacency between the stories solved
You can optionally turn off the Ceiling Adjacency if you are planing to export to a platform with it's own adjacency-solving routine (eg. IES-VE) or you are primarily interested in simulating each Story as a distinct unit with adiabatic floors and ceilings. This command will only be visible when more than one room is selected.
Create polyline boundaries around a selection of rooms. The command can return polylines for either the exterior border around the rooms or just the holes (or both).
Options
Mode
The calculation mode for creating boundaries. The options are Include Holes, Exclude Holes , and Holes Only
Merge Distance
The maximum distance between rooms below which the boundary will be drawn around the rooms together (instead of being separate for each room). Setting a non-zero value here will allow you to draw boundaries around rooms that have gaps in between them (crossing gaps up to the specified distance)
You can use the generated borders for aligning the existing rooms or creating new rooms. See the line commands for the full list of the available commands.
Generate suggested alignment axes for rooms using a selected line to specify the alignment direction. All generated axes will be parallel to the selected line and will fall along the common axes of the selected rooms.
Options
Distance
The distance with which room vertices will be aligned to common axes. This dictates the resolution with which common axes will be generated
All Common Axes
Select to have this command output all common axes of the rooms regardless of whether the rooms are already aligned to the axes. By default, only common axes to which the rooms are not already aligned are output
Show the selected rooms and shades in 3D. The preview shows up in a new floating window.
Options
Ceiling Adjacencies
Select to have the adjacency between the stories solved
Exclude Plenums
Select to have ceiling and floor plenum depths ignored. This results in each room in the table translating to a single room in 3D instead of a base room with plenums split off of it
Identify gaps smaller than a specified gap distance. Such gaps typically do not make the model invalid or un-simulate-able but they can create cases where adjacency solving fails to set interior boundary conditions where they likely should be. Small gaps can also result in sliver geometries for floors/ceilings in the case the ceiling adjacencies are solved.
Options
Gap Distance
The maximum distance between two rooms that is considered an unwanted adjacency gap. Differences between rooms that are higher than this distance are considered meaningful separations between rooms that should be preserved. Typical recommended values might be around 15 cm or 6''.
Check whether the selected rooms are valid/simulate-able. Valid models should export to any of the supported BEM engines without errors. Invalid models will have their errors presented in a table with the option to select the part of the model where the error originates so that it can be fixed.
