Using Feature Detection

Parts that will be created using an NC operation will require an NC process and toolpath. Features recognized by the feature detection function can be fed into NC templates to automate toolpath generation.

This feature is only available in the Part and NC environments.

Detect Features with CAD AI

Open the part on which you want to perform feature recognition.
Click the Feature Detection button.
Adjust the slider to set the Confidence Level as required.
For example, a confidence level of 75% means that only features recognized with 75% or higher confidence will be categorized. Features with confidence below this threshold will remain uncategorized.
Click Run Feature Detection to start the analysis.

When the process is complete, all recognized faces are assigned the color that corresponds to their detected Feature Type.

Recognized geometry is displayed in the Feature Detection pane.

Hierarchical Result Tree
- Features are first grouped into Type Groups (Pocket, Slot, Hole, Misc., Uncategorized).
- Within each Type Group, features are further classified into Feature Types (such as Closed Pocket With Floor, Hole With Flat Bottom, and so on).
- Each individual detected feature instance (actual geometry) appears as a Feature node under its corresponding Type.
Run Feature Detection button
Confidence Level slider and value (You can change the confidence level and generate different results without rerunning the analysis)
Assignment display - Click the associated radio button to display the option. Each face has two assignments:
- Default AI Assignment – Original CAD-AI result with full statistical data.
- Current Assignment – User-modified assignment.
- Additionally, you can display only the Changed Faces or Unchanged Faces
Reset assignment button - Reset all assignments, types, colors, and structure back to the default AI configuration.

Hierarchical Result Tree

All faces that belong to a single detected feature are treated as one Feature entity and are attached to that Feature node. This system provides a clear, structured, and manageable hierarchy that allows you to easily visualize, show/hide, rename, recolor, attach, detach, or reassign features as needed. This structured approach significantly improves feature management, visualization control, and downstream usage in NC automation workflows.

Delete an entry from the Tree

Right click on any entry in the tree and select Delete. The item is removed from the tree and any assignments are deleted - This action only removes the options that can be assigned to features, faces are not deleted from the part.

Visibility of selected features

Features that have been recognized can be hidden or displayed to make it easier to apply attributes to unassigned features.

Right-click on any entry in the tree and select Hide Other to change the visibility of items in that category.
Show All and Hide All options are available at the top of the Feature Detection pane.
The visibility bulb icon switches the visibility of features on or off.
- Click the icon on a row in the tree to change item visibility.
- Click the icon at the top of the tree to change visibility of all items in the tree,
