Adding and Editing Shapes
Editable geometrical forms can be added to a scene to enhance 3D views of selected data by highlighting features of interest. The visual effects available for shapes include clipping, edge contrast, fill, look-up tables, and window leveling (see Shape Properties and Settings). The visual effects that you create with shapes can be included in animated sequences and in screen captures (see Creating Animated Sequences and Saving Data).
The shapes that can be added to a scene are available on the Shapes panel, shown below.
Shapes panel
The different geometrical forms available in the Shapes panel — boxes, capsules, cylinders, planes, and spheres — are described in the table below.
| Description | ||
|---|---|---|
|
Box |
|
Creates a basic box-shaped object, or cuboid, that has six flat sides. All of its faces are rectangles and all of its angles are right angles.
You can resize and rotate the box, as well as change its position within a 2D or 3D view with the control points (see Editing Shapes). |
|
Capsule |
|
Creates a three-dimensional geometric shape consisting of a cylinder with two hemispherical caps on each end.
You can increase or decrease the height and radius of the capsule, rotate it, as well as change its position within a 2D or 3D view the control points (see Editing Shapes). |
|
Cylinder |
|
Creates an object with two identical flat ends that are circular and one curved side. The cylinder has the same cross-section from one end to the other.
You can increase or decrease the height and radius of the cylinder, rotate it, as well as change its position within a 2D or 3D view the control points (see Editing Shapes). |
|
Plane |
|
Creates a flat, two-dimensional surface that extends to the size of all selected visuals.
You can rotate the plane, as well as translate the plane with the handle (see Editing Shapes). |
|
Sphere |
|
Creates a 3D object shaped like a ball, in which every point on its surface is the same distance from the center.
You can resize the sphere, as well as change its position within a 2D or 3D view (see Editing Shapes). |
See Shape Properties and Settings for information about changing the visibility of shapes, applying effects, and other options.
How to Add a Shape
- Select the object to which you plan to add the shape in Data Properties and Settings panel, recommended.
The initial size and orientation of the new shape will be modelled on the selected object to provide the best initial fit.
- Click the required shape in the Shapes panel.
The selected shape appears in the Data Properties and Settings panel.
- Select the scene view to which you want to add the shape.
- Make the shape visible by clicking its associated Eye icon in the Data Properties and Settings panel.
The shape appears in the 2D views and 3D view of the selected scene.
- Select the shape in the Data Properties and Settings panel, if it is not already selected.
- Adjust the size and position of the shape, as required (see Editing Shapes for information about resizing, rotating, and repositioning shapes).
- Lock the shape by checking the Locked option, recommended.
- Select the visuals to which you want to apply the selected shape effects to in the Visual effects box.
- Select the required effect(s) and adjust their associated properties, as required (see Visual Effects and Properties).
NOTE You can apply the selected effects to the inside or outside of the shape.
Editing Shapes
If required, you can edit the size of a shape and its position in a 2D or 3D view by simply dragging the available control points. The control points available for each shape are described in the following table. For clarity, most shapes are shown in their 2D representations.
You can choose the colors that represent the different states of a control point — normal or selected (see Selecting the Colors Preferences).
