Sphere¶

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

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 as well as extracting measured features are as follows:

Select Pick on CAD Model in the drop-down list of Sphere to open the corresponding window.
Click on the highlighted sphere 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.
Click Confirm to save the reference sphere feature, and the reference sphere 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.
Right-click on that sphere feature group in the left-side tree view, select Extract Measured Feature and determine the measured model on which the feature will be extracted.
In the pop-up Sphere 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 sphere feature.
The measured sphere object will be displayed in the corresponding sphere feature group in 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

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