Sphere

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

Extraction​​

If the created feature is a reference feature, the corresponding measured feature can be extracted automatically or manually.

Note

Except for the From Features method, other creation methods support directly specifying features as reference features or measured features. If you define a feature as a reference feature, after importing at least one measurement model, you can extract the measured feature to generate feature pairs.

• Automatic Extraction: Enable Auto Extraction of Measured Values via Settings in the upper right corner of the software interface or check Extract Measured Feature in the creation window. The software will automatically extract the corresponding measured feature with default parameters after creating any reference feature.
• Manual Extraction: After creating a reference feature, right-click the feature group in the tree view on the left, select Extract Measured Feature and specify the measurement model to be extracted; you can specify Align Object in the extraction pop-up window.

Pick on CAD Model

Create sphere features by directly clicking on the geometric features shaped as spheres of the CAD model.

Note

• Before creating sphere 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 sphere features through picking on CAD model are as follows:

1. Select Pick on CAD Model in the drop-down list of Sphere to open the corresponding window.
2. Click on the highlighted sphere feature of the model in the 3D scene to create, and define the feature as Reference Feature or Measured Feature in the window of Pick on CAD Model.
3. Click Confirm to create the reference sphere or measured sphere, which will be displayed in the feature module of the left-side tree view.

Anchor

Directly anchor points on the model to create sphere features.

Note

Before creating plane features using the anchor method, please import a reference model or a measured model.

The steps for creating plane features through anchor are as follows:

1. Select Anchor in the drop-down list of Sphere to enable the anchor tool.
2. Click to add 4 points on the model in the 3D scene and define the feature as the Reference Feature or Measured Feature; then click Confirm in the Anchor window to create the reference sphere or measured sphere, which will be displayed in the feature module of the left-side tree view.

Fit

Create sphere features by fitting geometric features shaped as spheres through selecting points on the mesh model.

Note

• Before creating sphere 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 sphere features through fit are as follows:

Col

1. Select Fit in the drop-down list of Sphere 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 create the reference sphere or measured sphere, which will be displayed in the feature module of the left-side tree view.

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 Features

Create new sphere features based on existing features.

Note

• Before creating sphere features using this method, please import a reference model or a measured model, and ensure that there exists the corresponding features.
• This method does not support defining features: If the selected feature is a reference or measured feature, the created new feature can only be a reference or measured feature.
• If a reference feature is created, then you can extract the measured feature to generate feature pairs before importing at least one measured model.

The steps for creating sphere features from features are as follows:

1. In the drop-down list of Sphere > From Features, select the corresponding creation method.

   Creation Method	Description
   Sphere Average	Creates a new sphere feature by calculating the average of the selected spheres. Note If the selected features include reference features but some do not have measured features, the created feature will only have reference values without measurement values.

2. Select the corresponding created features, and click Confirm to create the feature, which will be displayed with the icon in the feature module of the left-side tree view.
