There are several cutting tools on the right toolbar.
The tool allows you to build a polygon or area with smooth borders that the cut area is projected on.
The tool is enabled/disabled using the button on the toolbar.
To build a polygon
To build an area with smooth borders (Lasso mode):
The part of the model to be projected on the area will be cut.
The tool is similar to the previous one, except that part of the model not to be projected on the area
will be cut. To activate/deactivate the tool, use the button on the toolbar.
The tool allows you to delete an area of a 3D model not associated with its other parts. To
activate/deactivate the tool, use the button on the toolbar.
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 Delete Area and Delete All Areas except Selected Area tools the following parameters can be set:
This parameters for each tool are set separately.
To set these parameters, click on the arrow on the right side of the appropriate tool button and select the Parameters... item and in the dialog box that appears, specify the required values.
Brush cut, Brush restore and Restore by mask tools allow to remove tissue within the sphere or cylinder and restore 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) |
![]() |
Brush restore |
![]() |
Restore by mask |
The cursor will look different depending on the mode that is selected. The cursor for Sphere mode is shown in Fig. 3.3, and the cursor for Cylinder mode is shown in Fig. 3.4.
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:
Brush restore tool allows you to perform the reverse process of brush cutting.
Restore by mask tool allows you to restore tissue by mask (this tool is used for
segmentation). It mask is not set, this mode is analogous to the Brush restore mode. For details
how to set mask see section 6.2.3.

The Grow (dilation) Shrink (erosion), Fill and Cut invisible volume tools allow to edit tissue within the 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) |
![]() |
Shrink (erosion) |
![]() |
Remove noise (opening) |
![]() |
Remove holes (closing) |
![]() |
Multi-segment growing |
![]() |
Fill |

Cut invisible volume |
The Grow (dilation) tool allows you to increase the volume by a certain value from the surface for 1 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 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 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 Cut invisible volume tool sets the mask according to the visible volume.
The tool allows you to delete areas similar to 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.
