Navigating in 3D Space

Mouse navigation

Navigate in 3D space using your mouse:

  • Hold the right mouse button and drag to rotate the view around the rotation center (center of currently available scene objects by default)
  • Scroll the mouse wheel to zoom in/out (zoom center = mouse position).
  • Hold both mouse buttons and drag to move the view freely. Alternatively, you can use the keyboard arrow keys to move the view in the respective arrow directions.
  • Click the middle mouse button / mouse wheel to center the view and set the clicked point as new rotation center.
HotkeySee the section 'Hotkeys' for a list of hotkeys that are available for the 3D viewer.
Mouse navigation

For Windows 7 and 8, multitouch monitors are supported for 3D navigation:

  • Use 3 fingers and drag to rotate the view.
  • Use 2 fingers to move, or pinch to zoom.
  • Use 1 finger to select the item under the finger or stylus, specify a point, or draw a curve.

Alternatively, 3D mice from 3dconnexion are also supported for navigation.

Showing/Hiding Objects

Show Hide Groups.PNG

The "Group Selector" allows you to show or hide objects (like scan data, constructed parts) by clicking the checkboxes left of the group description. Objects are grouped by type. For a more fine-grained selection, unfold a group by clicking on the little arrow left of the checkbox. As you proceed with the design, the list will become more and more populated.

A menu is available by right-clicking a group (e.g. right-click 'Anatomic shapes'). Among other things, this allows you to toggle transparency for an entire group of parts – a frequently used feature.

Unfold the 'Teeth' expander to switch visibility on a per-tooth basis. Unfold the 'Hidden' expander to see which parts are currently hidden. Use the 'Show all' button to show all parts available.

HotkeyInstead of using the 'Show all' button, you can also hold the <ALT> key to temporarily show all parts.

The Main Toolbar

The main toolbar presents options that are always available in the DentalCAD.

Save

Saves the current state of the CAD process in a "scene file" in the project folder. A scene file is a proprietary, version-specific file containing the complete state of the design process including scan information, current wizard step, and all modified settings and free-forming changes. To return to a specific point in the design if a design is likely to be revised, or for documentation of a design process, use 'Save scene as...' and label the specific design step. When reloaded, the CAD application appears exactly as it was. Alternatively, right-click the 'Save' button to save the current CAD window as a 3D PDF, or as an open .stl file with all objects included.

Expert/Wizard

Toggles between Wizard and Expert mode of exocad DentalCAD.

After starting the CAD module, a "Wizard" window will open, which will guide you step by step through the construction. Explore the options presented to you in each wizard screen, and click 'Next' to proceed to the next step. Of course, you can always use the 'Back' button to return to previous steps in the wizard. The wizard will present you reasonable default values (depending on the type of construction and the material selected) for all construction parameters. You are free to change them; any parameters you change in the wizard will be applied to all teeth in the construction.

Advanced users often chose to temporarily suspend the wizard at some stages in the construction, and to use the context menu instead. This gives you the option to apply specific functions or parameters to specific teeth/objects on the screen. Note that while the wizard is running, only a simplified version of the context menu is displayed. In expert mode, you get access to all the options available at this particular stage of the design. Click the wizard button to return to the wizard, which will resume at the same step as when it was suspended.

Tools

  • Measurement Tool - for measuring distance, thickness, or spacing for 3D objects on the screen.
  • Sectional View - a way to "slice" through objects which may be obscured.
  • Screen Shot - simple 2D screen shot, saved to the current project folder.
  • PDF Export - export the current CAD view as a 3D PDF file, can be viewed by anyone with the current version of Adobe reader.
  • Register Meshes - tool to align any meshes, enables 3-point matching between any mesh objects in the CAD window.
  • Magic Lantern - changes the position of the virtual "light" in the scene (just move the pop-up menu), useful for tricky margins.
  • Annotations - allows annotations in any CAD scene.
  • Add a picture - enables a 2D picture to be used for simple "smile design".
  • Select Tooth Colors - enables real-time selection of tooth color (only available with TruSmile module).
  • Add/Remove Mesh - allows adding meshes to the CAD window, and associating them with a function, such as "antagonist" (only available in expert mode).
  • Start DICOM Viewer, Virtual Articulator, or Nesting (only in expert mode, and only if module is installed).
  • Settings - Allows configuration options for language, tooth numbering, graphics, and other settings.
  • About - Shows the current version of the software and dongle ID.

Functional Selections

These additional CAD menu options only appear if the corresponding add-on module is installed, and the specified case requires them.

  • Articulator - Toggles the virtual articulator control window.
  • Show distances - Toggles a submenu providing a colored distance map for antagonist or adjacent spacing.
  • TruSmile - Toggles TruSmile mode on or off.

Add Custom View

Select 'Add custom view' to memorize the current viewpoint. Views are automatically named and listed below the 'Add View' button. To give the view a name, or rename a view, right-click the view. This is particularly useful for cases where multiple paths of insertion exist. The six arrows at the bottom of the menu allow instant access to the "orthogonal" views of the 3D workspace.

The Context Menu

Context menus are available to help you explore what functions are available at a particular stage in the construction.

TipIf you are new to this software, you will not need to use the context menu at all. But as you get more familiar with the software, you will appreciate the options there.

You can use the context menu to apply a certain function to:

  • All teeth (the "root" context menu)
  • Just one tooth (the "tooth-specific" context menu)
  • A group of previously selected teeth

You can open the "root" context menu by right-clicking the background in the CAD window. Functions you select here will be applied to all suitable parts of the construction. In expert mode, the "root" context menu also gives you access to some advanced dialogs, such as 'Visual properties' and 'Edit mesh, useful for identifying and correcting non-ideal meshes.

By right-clicking an individual tooth in the viewer, you can open the tooth-specific context menu. Items you select here will be applied only to the tooth you clicked.

In expert mode, to apply a context menu function to a group of teeth (but not to all), hold <CTRL> and click the teeth to mark (note that the teeth will change color). Then, right-click the background to see the context menu for the marked teeth.

The context menu will adapt itself to the current state of the construction, so the menu entries you see vary during the course of the design. So if you're looking for a particular feature, it's always a good idea to explore the context menu. Note that while the wizard is running, only a stripped-down version of the context menu is available.

A pop-down menu is available when clicking the bottom edge of the CAD window. It provides access to the most commonly used context menu selections.
