Work Planes: Reference planes, reference lines, levels.

The work plane is a 3D plane that you draw on. The set work plane tool, found on set on the Home tab, lets you enter the specify a new work plane and allow you to set the work plane to the type you want Fig.1.1.For example, when you are in a plan view and start sketching a floor, the work plane is set to the level you have started the floor sketch in. The most of views in Revit Architecture have predefined work planes set automatically when they are created. Views such as sections and elevations require you to manually pick a work plane in order to add 3D elements to those views. A work plane defines a surface on which you can build geometry. You can define a work plane by drawing a reference plane, picking a face from an existing element, or using an existing level as a reference (Gerg Denmchak, Tatjana Dzambazova, Eddy Krygiel 2010).

Rules using work planes

The work plane is set by selecting a reference plane/reference line, level plane, grid or solid geometry.
Many elements in Revit use the active work plane to know where to sketch or place objects.
The work plane is also used when you are modifying objects. When you drag or move an object, it is typically constrained to that plane.
When you set the work plane to be based on other selectable elements, it creates a parameter to the element you selected. If the underlying object is moved, the work plane is moved to stay aligned to it. Any objects created on the work plane will also update.

Name - Name of Level or name of Reference Plane

Pick a plane - Pick solid geometry or Reference Line planes

Pick a line - Pick a line and use work plane that was used to draw that line

Types of Reference Lines

Reference Plane - You can name the Reference Plane in the element

properties (Fig.1.5). Only shown in plan and can only be drawn in plan (Fig.1.4).

Reference Lines - Have four planes, two in middle and one at each end

(Tab to switch plane Fig.1.6). Only used when making families and model in-place (Fig.1.3).

Model In-Place

When you want to create an architectural feature or working on a Conservation Project, you often have to create walls, stairs, rails, and other features that is one off. The Model In-Place tool, found in the Component drop-down on the Home tab, lets you enter the model in-place command and allow you to create the objects (Fig.2.1). This tool allows you to draw solid geometry or voids using Extrusion, Blend, Revolve, Sweep, and Swept Blend (Fig.2.3). Each created form is assigned with a Family Category and Parameters that is later used to control visibility and behavior in the model (Fig.2.2). For example, assigning a sweep to the category Wall means that the model in-place geometry is a host wall family which allows you to insert windows and doors (Gerg Denmchak, Tatjana Dzambazova, Eddy Krygiel 2010).
