The tool allows you to build a polygon or an area with smooth borders that the cut area is projected on.
To build a polygon:
To build an area with smooth borders (Lasso mode):
The tool allows you to delete an area of a 3D model not associated with its other parts.
Activate/deactivate the tool by clicking the left/right/middle mouse button. To continue work with this tool, use the button with which the tool was activated. To learn more about tool control, see Section 1.14.
The tool is similar to the previous one, except that all areas excluding the selected area are deleted. To activate/deactivate the tool, use the button on the toolbar.
For the Delete Area and Delete All Areas except Selected Area tools, the following parameters can be set:
The parameters for each tool are set separately.
The Brush cut, Brush restore and Restore by mask tools allow to remove tissue within a sphere or cylinder and restore the tissue deleted by cutting tools. To select one of these tools (Brush cut, Brush restore, Restore by mask) and modes (Sphere, Cylinder), click the arrow on the right side of the tool buttons. The button will look different depending on the tool that was used last:
|Brush cut (is selected by default)|
|Restore by mask|
To activate/deactivate the tool, click on the left side of the tool button. If any tool is activated, the button is highlighted.
To cut tissue:
The Brush restore tool allows you to perform the reverse process of brush cutting.
The Restore by mask tool allows you to restore tissue by mask (this tool is used for segmentation). If mask is not set, this mode is analogous to the Brush restore mode. For details how to set mask, see Section 6.2.3.
Functionality is available in the Pro edition
The Grow (dilation), Shrink (erosion), Fill and Cut invisible volume tools allow to edit tissue within special algorithms. The Multi-segment growing tool allows you to edit segmented structures. To select one of these tools, click the arrow on the right side of the tool buttons. The button will look different depending on the tool that was used last:
|Grow (dilation) (set by default)|
|Remove noise (opening)|
|Remove holes (closing)|
|Cut invisible volume|
The Grow (dilation) tool allows you to increase the volume by a certain value from the surface in one iteration. This value is specified in the Settings menu of this tool (parameter Growing radius). The increase is possible only within the original volume, for example, after the use of cutting tools. When you use this tool to edit a segmented structure, an increase is possible only within the mask. The tool is used to fine-tune the structure if, initially, the required volume was not obtained.
The Shrink (erosion) tool performs the opposite action. The reduction value is specified by the parameter Growing/Shrinking radius.
The Remove noise (opening) tool allows to remove noise from the volume. This tool is equivalent to the consistently applied tools Shrink (erosion) and Grow (dilation).
The Remove holes (closing) tool allows to remove little holes from the volume. This tool is equivalent to the consistently applied tools Grow (dilation) and Shrink (erosion).
The Multi-Segment Growing tool allows you to simultaneously build several structures and base volume. It is used to edit segmented structures (see Section 6.4.6). If the tool is applied only to the base volume, then it works like the Grow (dilation) tool.
The Fill tool allows you to fill the voids in the volume. If you are working with segmented structures, the tool is used to improve structures, built on a "grainy" mask. Such masks are typical, for example, for kidneys.
The tool allows you to delete areas resembling the medical equipment table. To delete, click the button on the toolbar.

To undo or redo the last action associated with cutting, use the Undo and Redo buttons.
