Many aspects of cross-section manipulation are the same as for other objects, such as lights. You can modify using transform handles and properties; see:

• Move, scale, and rotate objects visually
• Move, rotate and scale objects by typing numbers

One difference from other object manipulation is that by default, you can only move a cross-section along the X, Y, or Z axis. To move a cross-section in a non-axis direction, you must rotate it and its pivot to align with the axis along which you want to move the cross-section. Do this as follows:

1. Select the cross-section and turn on transform handles.
2. Click a rotation handle and enter the number of degrees you want to rotate.
3. Press Insert to show pivot handles.
4. Click the pivot handle that corresponds to the rotation handle you clicked earlier. Enter the same number of degrees of rotation.
5. Press Insert to show transform handles again and drag the cross-section along the axis it is aligned with.

To add or remove objects cut by the cross-section:

1. Select the objects you want to add or remove from the cross-section.
2. Right-click the cross-section icon in the Cross-Sections overlay and select Properties.
3. In the Properties dialog box that opens, click Associated objects: Choose.

   

4. Select Add Selection To or Remove Selection From.

Showcase includes some automatic cross-section placement options that you can use as follows:

1. Right-click the cross-section icon in the Cross-Sections overlay and select Properties.
2. Click the Choose button beside Auto placement.

   

3. Choose from the following options:
   • Align with XYZ: This rotates the cross-section to the nearest XYZ axis; in other words, flat, or directly upright along the Y or Z axis.
   • Center in Bounding Box: Moves the cross-section to the center of the bounding box of the currently selected object or objects.
   • Flip Section: Rotates a plane cross-section 180 degrees. (Not available for corner cross-sections.) The side of the object that was previously visible behind the cross-section becomes hidden, and vice versa.

Tip: To flip a corner cross-section, show its transform handles, click a scale handle, and enter -1.
