SETTING UP WORK PLANES

STEP 12

Start an In-Place Mass or a new Mass Family.

In the Home tab>Draw panel, select a drawing tool. The active work plane displays as a heavy purple outline.

In the Modify I Place Lines tab>Draw panel, click (Draw on Face).

Roll the cursor over the face of an existing element. It highlights and you can then draw the sketch, as shown in Figure.

You can move directly to another face and continue drawing sketches.

12

As you prepare to draw conceptual massing elements, you first need to understand how to set the work plane for the profiles from which you are going to build. Autodesk Revit uses levels, existing faces, and reference planes as work planes on which you can sketch the geometry for solid and void forms.

tto see he workplane in your view, in the Work Plane panel click on (Show WorkPlane)

WORK PLANE BY FACE

STEP 11 In a Plan, Elevation, or Section view, draw a reference plane (RP)

Reference planes cannot be drawn in 3D views.Click (Modify) and select the reference plane.

In Properties, type a Name.

If you are in a plan view, the related level is the active work plane by default.

CREATING FORMSThe Conceptual Massing tools in Autodesk Revit provide advanced capabilities to quickly and easily create and complex massing. Six types of forms that can be created are Extrusions, Sweeps, Blends, Swept Blends, Revolves, and Lofts, as shown in Figure. Each method uses sketched 20profiles as the basis ofthe 3D shape.

Extrusion: Pushes a single profile in a single direction.Revolve: Rotates a profile around an axisSweep: Extends a profile along a pathBlend: Links two profiles together.Swept Blend: Connects two profiles along a pathLoft: Connects multiple profiles that do not need to parallel planes.

These methods apply to both In-Place Masses and Conceptual Mass families. You can create solid forms or void forms.

Before you start drawing the profiles paths, you should determine whether the sketch should be drawn on the face of an existing element or on a Work Plane.

EXTRUSIONSSTEP 14Start an In-Place Mass in a project or a new Conceptual Mass family.

In the Draw panel, select a drawing tool and establish the appropriate work plane.

Create a closed profile.

Click (Modify).

Select the closed profile.

In the Modify I Lines tab -Form panel, click (CreateForm). Autodesk Revit extrudes a solid form from the profile.

The Modify I Form tab opens, in which you can make changes to the form.

Click (Modify) and then press (Esc) or click in empty space to release the selection.

In an In-Place Mass, click (Finish Mass) to complete the mass.

Some shapes, such as a circle, have options for the shape of the form. Select the shape you want to use from the options displayed on the screen.

REVOLVESTEP 15In the Draw panel, select a drawing tool and establish the appropriate work plane.

Sketch an open or closed profile. If you use an open profile, Autodesk Revit creates a surface revolve.

In the same reference plane or level, use / (line) or other drawing tools to create the axis.

Click (Modify).Select the axis line and profile.

In the Modify I Lines tab>Form panel, click (Create Form) Autodesk Revit revolves the profile about the axis to create the form.

While you are still in the Modify I Form tab, select the entire form. In Properties, modify the Start Angle and End Angle.

15

SWEEPSSTEP 16Start an In-Place Mass in a project or a new Conceptual Mass family.

In the Draw panel, select a drawing tool and establish theappropriate work plane.

Sketch a path for the sweep to follow. Click (Modify).

In the Draw panel, click “ (Point Element) and click on the path.

Click (Modify) and Open a 3D view.

Select the Point Element in the view window. A reference plane perpendicular to the path is displayed. It becomes the work plane on which to draw the profile for a sweep.

Use the drawing tools to sketch a profile on the new reference plane. A single-segment path can be used with an open or closed profile. A multi-segment path requires a closed profile.

Click (Modify) and select both the path and the profile.

In the Modify I Multi-select or Lines tab>Form panel, click (Create Form).

Autodesk Revit creates a solid form based on sweeping the profile along the path.

DYNAMIC EDITINGSTEP 22When a completed In-Place Mass element is selected, you can modify the length of its faces by dragging the controls, as shown on the left in Figure 1-37. However, for more precise modification, you can edit the mass in-place.

In Edit In-Place mode, you have direct access to the faces, edges, and vertices of a solid or void form. You can quickly and easily manipulate these sub-elements and create new edges and profiles. Select the in-place mass, and, in the Modify I Mass tab>Model panel, click (Edit In-Place)

If you are working in a Conceptual Mass family, these dynamic features are available in the family file but not when the mass family is inserted into a project.

To return the form to its component parts, select the mass element, in the Modify I Form tab>Form Element panel, click (Dissolve). Once you have done this, you need to remake the entire form again.

22

STEP 23In a Conceptual Mass family or the In-Place Edit mode of an In-Place Mass element, open a 3D view.

Select a sub-element (face, edge, or vertex) The 3D control is displayed.

Press <Tab> to cycle between sub-elements as needed to select the right one.

Press the <Spacebar> to toggle between local and global coordinates.

To move the sub-element along an axis, click and drag a single axis of the 3D control, as shown.

To move the Sub-element along a plane, click and drag the plane indicator on the 3D control.

Click (Modify) to end the command, or select another element or sub-element.

STEP 23You can also use (Move) and (Rotate) when you select a face, an edge, or a vertex. In the example the face has been rotated.

23

STEP 24If you want to remove a face, an edge, or a vertex, select it and click (Delete) or press <Delete>.

In the example in a vertex has been selected and deleted.

24

STEP 25You can lock a mass element so that the profiles in a form work together rather than separately. In the example, when you modify an edge, the form on the left is not locked and only the selected edge moves while the form on the right is locked and the entire form based on that profile moves.

25

STEP 26Autodesk Revit does not automatically display the vertices, interior profiles, etc., for forms. X-Ray mode makes the surfaces of a form transparent, while displaying all key geometric data at the same time.

Click anywhere on the form for which you want to see the geometric skeleton.

In the Modify I Form tab>Form Element panel, click (X-Ray), or right-click and select X-Ray. The x-ray version displays implicit paths, form axes, and control nodes that were to create the selected form.

Explicit paths are paths that you sketched.Implicit paths are lines that Revit used to create the form.Control Nodes are points where profiles intersect with paths.

To turn off X-Ray mode select the form again and click (X-Ray).

Only one form can have X-Ray on at a time and it is in this mode in every view.

STEP 28In the Modify I Form tab>Form Element panel, click (Add Edge) or right-click and select Add Edge.

Move your cursor over a face. A new edge that reflects the geometry displays. You can also pick two points at the vertices or edges of a face.

28

You can also add edges and profiles to existing forms and then modify the resulting edges, faces, and vertices. An edge can be added to the sides of a form, while a profile can be added along the path of the profile.

Once the edge or profile is placed, you can use the 3D control to create new shapes.

ADDING EDGES AND PROFILES

STEP 29In the Modify I Form tab>Form Element panel, click (Add Profile) or right-click and select Add Profile.

A new profile displays on the selected form when the cursor is moved onto and follows it.

The profile automatically adjusts its shape to match the.exterior of the form wherever the cursor is located, as shown
