Modify type properties to change a floor's structure, default thickness, function, and more.
To change type properties, select an element and click Modify tab
Properties panel
(Type Properties). Changes to type properties apply to all instances in the project.
| Name | Description |
|---|---|
| Construction | |
| Structure | Creates the composition of a compound floor. See Compound Structure. |
| Default Thickness | Indicates the thickness of a floor type, which is determined by the cumulative thickness of its layers. |
| Function | Indicates whether a floor is interior or exterior. Function is used in scheduling and to create filters to simplify a model when exporting. |
| Additional Top/Exterior Offset | Specifies an additional offset from the top/exterior rebar cover. This allows placing multiple rebar elements together in different area reinforcement layers. |
| Additional Bottom/Interior Offset | Specifies an additional offset from the bottom/interior rebar cover. This allows placing multiple rebar elements together in different area reinforcement layers. |
| Additional Offset | Specifies an additional offset from the rebar cover. This allows placing multiple rebar elements together in different path reinforcement layers. |
| Graphics | |
| Coarse Scale Fill Pattern | Specifies a fill pattern for a floor in a coarse-scale view. See View Properties. |
| Coarse Scale Fill Color | Applies a color to the fill pattern for a floor in a coarse-scale view. |
| Materials and Finishes | |
| Structural Material | Specifies a material for the structure of the element. This information can be included in schedules. Click the value box to open the Material Browser. See Materials. |
| Identity Data | |
| Keynote | Add or edit the floor keynote. Click in the value box to open the Keynotes dialog. See Keynotes. |
| Model | The model type of the floor. |
| Manufacturer | The manufacturer of the flooring material. |
| Type Comments | Comments about the floor type. This information can be included in a schedule. |
| URL | Link for a manufacturer web page. |
| Description | Provides a description of the floor. |
| Assembly description | Describes the assembly based on the assembly code selection. This is a read-only value. |
| Assembly Code | Uniformat assembly code selected from a hierarchical list. |
| Type Mark | A value to designate the specific floor. This value must be unique for each element in a project. Revit warns you when the number value is already used but allows you to continue using it. You can see the warning using the Review Warnings tool. See Reviewing Warning Messages. |
| Cost | Cost of the flooring. This can be included in a schedule. |
| Analytical Properties | |
| Heat Transfer Coefficient (U) | Used in calculating the heat transfer, typically by convection or phase change between a fluid and a solid. |
| Thermal mass | A measure of a building element's ability to store heat, the product of each material layer mass and specific heat capacity. |
| Absorptance | A measure of a building element's ability to absorb radiation, the ratio of radiation absorbed to the incident.
Note: The default is 0.1. When using this data for thermal analysis, specify a value suitable for the type of analysis, such as whole building energy simulation.
|
| Roughness | An index value from 1-6 (where 1 is rough, 6 is smooth, and 3 being typical for most building materials) used to represent the roughness of a surface for the purposes of determining values of air film resistance in many common thermal calculation and simulation tools.
Note: The default is 1. When using this data for thermal analysis, specify a value suitable for the type of analysis, such as whole building energy simulation.
