To change type properties, select an element and click Modify tabProperties panel (Type Properties). Changes to type properties apply to all instances in the project.

Name	Description
Construction
Structure	Specifies a floor layer. Select the Edit button to add, change, or delete a floor layer. See Edit Layers in a Compound Structure.

Coarse Scale Fill Color	Applies a color to the fill pattern for an element 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.
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 Resistance (R)	A measure of a temperature difference, by which an object, or material, resist a heat flow (heat per time unit or thermal resistance.
Thermal Mass	Equivalent to thermal capacitance or heat capacity.
Absorptance	A measure of the ability of an object to absorb radiation, equal to the ratio of the absorbed radiant flux to the incident flux.
Roughness	A measure of the texture of a surface.
Identity Data
Type Image	Displays a user-defined image file that represents the element. See About Managing Images.
Keynote	Add or edit the element keynote. Click in the value box to open the Keynotes dialog. See Keynotes.
Model	The manufacturer internal number.
Manufacturer	The manufacturer of the element materials.
Type Comments	A field for placing general comments about the element type. This information can be included in a schedule.
URL	A link to a web page that may contain type specific information.
Description	Enter or edit the description of the element.
Assembly Description	Describes the assembly based on the assembly code selection. This is a read-only parameter.
Assembly Code	A Uniformat assembly code selected from a hierarchical list.
Type Mark	A value that designates the specific element. 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	The pricing of the element.
