Rectangle

In the Create Features toolbar, click Rectangle to expand the dropdown list, providing options for Pick on CAD Model, Anchor, Numerically, Fit, and From Cross-Section.

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 rectangle features by directly picking geometric features shaped like rectangles on the CAD model.

Note

• Before creating rectangle features using the picking method on CAD models, please import the reference model first.
• This method supports specifying features as reference or measurement features.
• If defining a feature as a reference feature, at least one measurement model must be imported before extracting measurement features to generate feature pairs.
• You can also directly use the CAD Automatic Creation method in the Auxiliary Feature Creation toolbar to automatically create features.

The steps to create rectangle features using the picking method on CAD models are as follows:

1. In the dropdown list of the rectangle, select Pick on CAD Model to open the corresponding window.
2. Click on the highlighted rectangle feature on the model in the 3D scene to create it, and define the feature as a Reference Feature or Measurement Feature in the Pick on CAD Model window.
3. Click Confirm to create the feature, which will then be displayed in the left directory tree under the feature module as a rectangle reference object or a rectangle measurement object.

Anchor

Create rectangle features by directly anchoring points on the model.

Note

• Before creating rectangle features using the anchoring method, please import the reference model or measurement model.
• This method supports specifying features as reference or measurement features.
• If defining a feature as a reference feature, at least one measurement model must be imported before extracting measurement features to generate feature pairs.

The steps to create rectangle features using the anchoring method are as follows:

1. In the dropdown list of the rectangle, select Anchor to enable the anchoring tool.
2. Click on 3 points on the model in the 3D scene, define the feature as a Reference Feature or Measurement Feature in the Anchor window, and then click Apply to create the feature, which will then be displayed in the left directory tree under the feature module as a rectangle reference object or a rectangle measurement object.

Numerically

Note

• Before creating rectangle features using the numerically method, please import the reference model or measurement model.
• This method supports specifying features as reference or measurement features.
• If defining a feature as a reference feature, at least one measurement model must be imported before extracting measurement features to generate feature pairs.

Parameter Description

• Angle: Find an axis in the plane of the rectangle that determines the length direction of the rectangle together with the specified angle; the range is 0° ≤ 360°, and you can input numbers with up to 4 decimal places.
• Length: The length of the rectangle, which can be input as greater than or equal to 1, with up to 4 decimal places after the decimal point and up to 13 digits before the decimal point.
• Width: The width of the rectangle, which can be input as greater than or equal to 1, with up to 4 decimal places after the decimal point and up to 13 digits before the decimal point.

Operation Instructions

1. In the dropdown list of the rectangle, select Numerically to open the corresponding window.
2. Input the X/Y/Z axis coordinates of the rectangle's center point, normal, angle, length, and width, and define the feature as a Reference Feature or Measurement Feature.
3. Click Confirm to create the feature, which will then be displayed in the left directory tree under the feature module as a rectangle reference object or a rectangle measurement object.

Fit

Create rectangle features by selecting some points on the mesh model for fitting.

Note

• Before creating rectangle features using the fit method, please import the reference model or measurement model (must be a mesh model).
• This method supports specifying features as reference or measurement features.
• If defining a feature as a reference feature, at least one measurement model must be imported before extracting measurement features to generate feature pairs.

The steps to create rectangle features using the fit method are as follows:

1. In the dropdown list of the rectangle, select Fit to open the corresponding window.
2. Edit parameters to exclude noise points, and define the feature as a Reference Feature or Measurement Feature.
3. After completing the relevant settings, select the tool from the toolbar at the bottom of the 3D scene, then select the area on the model that needs to be fitted; click Confirm to create the feature, which will then be displayed in the left directory tree under the feature module as a rectangle reference object or a rectangle measurement object.

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 areas on the mesh model according to curvature. Note This function cannot select point cloud data. Other selection tools and penetration functions cannot 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 rectangular features based on existing cross sections.

Note

• Before using the from cross-section method to create rectangular features, ensure that at least one cross section has been created.
• This method supports designating features as reference features or measurement features.
• If the defined feature is set as a reference feature, measurement features will be extracted to generate feature pairs, but ensure that there is a cross section containing the measurement cross section.

The steps to create rectangular features using the from cross-section method are as follows:

1. In the dropdown list for rectangles, select From Cross-Section > Click on the CAD Section / Fit / Anchor to open the corresponding window:

   • Click on the CAD Section: After selecting the cross section, click directly on the reference cross section, then define the feature as a reference feature or measurement feature in the window.

   • Fit: After selecting the cross section, click directly on the reference or measurement cross section, then set whether to exclude noise points in the window, and define the feature as a reference feature or measurement feature.

     Note

     The normal of the rectangular feature created by fitting should deviate within 5° from the normal of the cross section, i.e., both the forward and reverse normals, for successful creation.

   • Anchor: After selecting the cross section, click directly on 3 points along the cross section line, and define the feature as a reference feature or measurement feature.

     Note

     The 3 points selected cannot be collinear.

2. Click Confirm to create the feature, which will then be displayed in the left directory tree under the feature module as a rectangular reference object or rectangular measurement object.
