To select a cross-section:
- Click
its icon in the Cross-Sections overlay. The cross-section is highlighted
in the scene.
There are two components
of a cross-section that you can see on-screen:
- Grip: this is
the plane (or set of planes, for a corner cross-section) that crosses
the object.
- Outline: the
lines indicating where the surface of the object(s) are intersected
by the plane(s).
To turn outlines on or off:
- Right-click the cross-section icon in
the Cross-Sections overlay and select Properties.
- Select or deselect Enable outline in
the properties dialog box that opens.
To toggle grip visibility,
press Shift-X.
To change the color of the grip and outline:
- Right-click the cross-section icon in
the Cross-Sections overlay and select Properties.
- Click the color swatch in the properties
dialog box that opens.
- Select a new color with the color picker
that opens, then close the color picker.
- In the cross-section properties dialog
box, use the color shader to darken or lighten the color.
The outline color changes
to match your selection. The grip also takes on the same color. This
makes it easier to differentiate between cross-sections when you
have many of them in a scene.
You can hide a cross-section
as you would objects; see
Hide and show objects.
When a cross-section is hidden, the object it cuts appears fully
intact. You can add cross-sections to model alternatives and trigger
their visibility using the storyboard.
