Bottom Toolbar

The Bottom Toolbar is the main interaction panel of the 3D Viewer.
It provides quick access to tools used for navigation, selection, visualization, and measurement.

Using this toolbar you can:

Select elements in the scene
Navigate the 3D workspace
Switch camera projection modes
Change visualization styles
Measure distances, angles, and geometry relationships

Selection Tool

The Selection Tool controls how elements are selected in the 3D scene.

Available selection modes

Default Mode – Select objects one by one. Ideal for precise inspection or editing of individual components.
Area Selection Mode – Allows box selection: click and drag to select multiple objects simultaneously. Useful when working with grouped elements or applying transformations to several parts at once.
Ray Drill Select – Selects objects along a virtual ray cast from the camera through the cursor. Instead of picking just the first object, this mode identifies all objects intersected by the ray.

💡 Tip: Use Area Selection when working with multiple parts.

Navigation Modes

Navigation modes allow you to explore the 3D environment.

Navigate (3D Pan)

Provides free navigation inside the scene.

Control	Action
Left mouse button + drag	Rotate the view
Mouse wheel	Zoom toward the cursor
Mouse wheel + drag	Pan the scene
Right mouse button + drag	Dolly zoom

💡 Tip: The pivot point defines the center of rotation.

Turntable

Rotates the scene around a fixed vertical axis.

Mouse Walk

Provides first-person navigation using the mouse.

Keyboard Walk

Provides first-person navigation using keyboard controls.

Camera Settings

Camera settings control how the 3D scene is projected.

Perspective View
Provides realistic depth perception.

Orthographic View
Maintains true dimensions without perspective distortion.

💡 Tip: Use Orthographic View when performing measurements.

Visualization Settings

Visualization settings allow you to change how geometry is displayed.

Rendering modes

Shading with edges – Renders faces and outlines, offering a clear and detailed view of geometry.

Shading – Displays shaded faces without edge lines.
Tessellation edges – Displays only mesh edges.
X-Ray – Makes surrounding geometry transparent while keeping selected objects visible.
Gooch – Applies mid-tone shading that highlights edges.
Toon – Displays stylized shading emphasizing object contours.
