The 'Free-Forming' window gives you access to the following features:
- Anatomic forming: Changing the shape of the tooth anatomy, while taking advantage of the intelligent library models
- Virtual wax knife - adding or removing material, smoothing
- Adaptation of chewing surface to the antagonist, contacts to the adjacent teeth, and pontics to the gingiva
- Paint & Pull
- Attachment Editor
Click & drag on the tooth to change its shape.
During free-forming, it's very useful to visualize distances to antagonists or adjacents - see section "Visualizing contacts and occlusions" for details.
Use the buttons - to change the area that you're editing:
By expanding the 'Advanced options', you can access two options allowing you to restrict the movement in certain ways. Using Movement , you can restrict movements to occlusal direction (up/down) only. Using Hold parts fixed , you can hold certain parts of the tooth fixed, either the cusp tips or the equator.
- PAINT & PULL , you can paint areas that you wish to move by brush in Paint moving parts [A] .
Then, click on Pull moving parts with mouse [B] to move, pull, deform, scale, or rotate the parts of the surface that you have painted.
Switch to Advanced editing to have full control over the elastic and moving parts.
Free-Forming Adjustments – Adding or Removing Material, Smoothing
Click the 'Free' tab to switch to the "Virtual wax knife", which allows you to add or remove material. You can toggle between Add/Remove  material and Smooth/Flatten .
To add or remove material, click on the tooth and hold Add/Remove . The longer you hold it, the more material will be added.
Activate Smooth/Flatten , click and hold the mouse button on the parts you'd like to smooth.
Adjusting the Brush
Using the slider Strength , you can adjust the speed at which material is added or removed while you hold the mouse button (or the amount of smoothing when in "Smooth/Flatten" mode). The slider Brush size  controls the brush size, that is the affected area around the mouse pointer.
Adding or removing attachments in free-forming ("boolean operations")
In the "ATT." tab, you can add or remove (cut out) library parts (such as attachments or bolts), or even certain STLs loaded from file, to your restoration.
