The properties of space objects are illustrated and described below. Note that some properties are limited to specific space types. For example, a 2D space does not have any height properties.
| Property | Space Type | Description |
|---|---|---|
| Description | All | User-defined description of the space. |
| Layer | All | Specifies the layer on which the space is placed. By default the layer assignment is defined in the space style. |
| Style | All | Specifies the space style. The style defined in the space tool is the default. |
| Name | All | The name of the space. If a list definition has been specified in the space style, the defined list of names is available as a drop-down list. |
| Tag | All (only available during space add and in tool properties) | Specifies a space tag to be inserted when adding the space. Space tags are available in the sample drawings shipped with the software. You can also create your own space tags. |
| Associative | All | Indicates whether the space is associative. The geometry of an associative space is dependent on its boundary objects. You can disconnect the associativity of a space after adding it. Note: If you insert a non-associative space, the Associative field reads No and is read-only.
|
| Offset Boundaries | All | Specifies the calculation type by which the 4 space boundaries (base boundary, net boundary, usable boundary, and gross boundary) are calculated.
|
| Calculation Modifiers | All | Identifies any calculation modifiers for the space. A calculation modifier is a formula that modifies area and perimeter values of the boundaries of the space. Note: To apply the modifier to the net, usable, and gross boundaries of a space, you need to create and apply a property set definition that contains properties for the calculated area and perimeter values for those 3 boundaries.
|
| Space/Zone Manager | All | Accesses the Space/Zone Manager worksheet, in which you enter information used to process spaces in engineering applications. |
| Create Type | Non-Associative Spaces (only available during adding a space and in tool properties) | Specifies the type of space to be created:
|
| Segment type | Non-associative polygonal spaces (only available during adding a space and in tool properties) | Specifies whether the individual segments of a polygonal space are lines or arcs. |
| Property | Space Type | Description |
|---|---|---|
| Allow overlapping spaces | Associative spaces (only available during adding a space and in tool properties) | Specifies whether you can generate spaces from boundary objects that already contain a space. By default, this setting is set to No. |
| Property | Space Type | Description |
|---|---|---|
| Geometry Type | All | Specifies the geometry type of the space to be created:
|
| Overall Space Height | 3D spaces | Specifies the overall height of the space, including floor to ceiling height, floor thickness, ceiling thickness, space above ceiling, and space below floor. Note: This value is read-only for 3D freeform spaces.
|
| Ceiling height | 3D spaces | Specifies the ceiling height of the space. Note: This height is calculated from the top of the floor to the bottom of the ceiling. You can define additional floor and ceiling thickness.
|
| Floor thickness | 3D spaces | Specifies the thickness of the floor. If the floor thickness is set to 0, no floor is displayed. |
| Ceiling thickness | 3D spaces | Specifies the thickness of the ceiling. If the ceiling thickness is set to 0, no ceiling is displayed. |
| Height above ceiling | 3D spaces | Specifies the distance between the top of the space ceiling to the top of the space. |
| Height below floor | 3D spaces | Specifies the distance between the bottom of the space floor and the bottom of the space. |
| Default surface height | 3D spaces | Specifies the combined height of ceiling height, ceiling thickness, and height above ceiling. |
| Justification | Extruded 3D spaces | Specifies the relative vertical position of the space insertion point on the space as one of the following:
3D freeform spaces are always justified to the top of floor. |
| Property | Space Type | Description |
|---|---|---|
| Length | All | Specifies the length of the space. |
| Width | All | Specifies the width of the space. |
| Base area | All | Displays the base area of the space. When inserting a space based on target dimensions, you can enter a base area value if you have not chosen to constrain the area. |
| Base Perimeter | All | Displays the base perimeter of the space. |
| Base Volume | 3D spaces | Displays the base volume of the space. |
| Property | Space Type | Description |
|---|---|---|
| Calculation Plane 1 + 2 Height | 3D freeform spaces | Specifies the height for calculating the areas of a 3D freeform space on 2 different calculation planes. This would be useful to calculate the rentable area of a room directly under the roof at 2 different room heights. |
| Property | Space Type | Description |
|---|---|---|
| Target area | Non-associative spaces based on target dimensions | Displays the target area defined in the space style. |
| Maximum area | Non-associative spaces based on target dimensions | Displays the maximum area defined in the space style. |
| Minimum area | Non-associative spaces based on target dimensions | Displays the minimum area defined in the space style. |
| Property | Space Type | Description |
|---|---|---|
| Rotation | Non-associative spaces | Specifies the rotation of the space. |
| Elevation | Non-associative spaces | Specifies the elevation of the space. |
| Additional Information | Non-associative spaces | Specifies the location and coordinate system of the space. |
In addition to these object properties there are a number of schedule properties that can be attached and calculated for a space.
