Slot

In the Create Features toolbar, click Slot to expand the drop-down list, where you can select Pick on CAD Model, Fit and From Cross-Section creation methods.

Pick on CAD Model

Create slot features by directly clicking on the geometric features shaped as slots of the CAD model.

Note

• Before creating slot features using the CAD auto creation method, please import a reference model.
• This method supports specifying features as reference features or measured features.
• If you Define the Feature as Reference Feature, then you can extract the measured feature to generate feature pairs before importing at least one measured model.
• You can also use the CAD Auto Create method in the Assisted Feature Creation toolbar to automatically create features.

The steps for creating slot features through picking on CAD model as well as extracting measured features are as follows:

1. Select Pick on CAD Model in the drop-down list of Slot to open the corresponding window.
2. Click on the highlighted slot feature of the model in the 3D scene to create, and define the feature as Reference Feature in the window of Pick on CAD Model.

3. Click Confirm to save the reference slot feature, and the reference slot object will be displayed in the feature module in the left-side tree view.

   Note

   If you check Extract Measured Feature (you can enable Auto Extract Measured Features in Setting > Feature), then the corresponding measured feature will be the automatically extracted after you create a reference feature.

4. Right-click on that slot feature group in the left-side tree view, select Extract Measured Feature and determine the measured model on which the feature will be extracted.

5. In the pop-up Slot window, select an align mode, edit parameters including max distance, boundary exclusion distance and so on, as well as set eliminate noise, and click Confirm to create the corresponding measured slot feature.
6. The measured slot object will be displayed in the corresponding slot feature group in the left-side tree view.

Fit

Create slot features by fitting geometric features shaped as slots through selecting points on the mesh model.

Note

• Before creating slot features using the fit method, please import a reference model or a measured model (meshed).
• This method supports specifying features as reference features or measured features.
• If you Define the Feature as Reference Feature, then you can extract the measured feature to generate feature pairs before importing at least one measured model.

The steps for creating slot features through fit are as follows:

Col

1. Select Fit in the drop-down list of Slot to open the corresponding window.
2. Edit parameters including eliminate noise, as well as define the feature as reference feature or measured feature.

3. After completing relevant settings, you can select tools in the toolbar under the 3D scene, and select areas to be fitted on the model; then click Confirm to save the slot feature, which will be displayed in the feature module in the left-side tree view.

   Note

   If you check Extract Measured Feature (you can enable Auto Extract Measured Features in Setting > Feature), then the corresponding measured feature will be the automatically extracted after you create a reference feature.

The introduction to toolbar as well as shortcuts is as follows:

Icon	Name	Description
	Sphere	Select mesh vertices on the surface of the mesh model to choose the fitting region. Note After enabling this function, other selection tools or the select through function can not be used.
	Magic Wand	Automatically select adjacent regions on the surface of the mesh model based on curvature. Note After enabling this function, other selection tools or the select through function can not be used.
	Select Through	Disabled by default, which means only visible surfaces can be selected; It can be enabled to select both the front and back regions of the model.
	Rectangle	Select / Deselect the data area in the form of rectangle.
	Polygon	Select / Deselect the data area in the form of polygon.
	Lasso	Select / Deselect the data area in the form of lasso.
	Brush	Use brush (support brush adjusting) to select / deselect the data area.

Function	Shortcut
Select	Shift+left-button
Deselect	Ctrl+left-button
Adjust the size brush	Shift+left-button

Note

For more shortcuts, please refer to > Shortcut Instructions in the top right corner of the interface.

From Cross-Section

Create slot features based on existing cross-sections.

Note

• Before creating slot features using this method, please ensure that there exists at least one created cross-section.
• This method supports specifying features as reference features or measured features
• If you Define the Feature as Reference Feature, then you can extract the measured feature to generate feature pairs before importing at least one measured model.

The steps for creating slot features from cross-sections are as follows:

Col

1. Select From Cross-Section in the drop-down list of Slot to open the corresponding window.
2. Select cross-section and edit parameters including remove outliers, as well as define the feature as reference feature or measured feature.

3. Click Confirm to save the slot feature, which will be displayed in the feature module in the left-side tree view.

   Note

   If you check Extract Measured Feature (you can enable Auto Extract Measured Features in Setting > Feature), then the corresponding measured feature will be the automatically extracted after you create a reference feature.
