Create from Cross-Section

Create features through cross-sections.

Note

Features created using the Pick on CAD Section creation method are reference features by default.

Creation Steps

PointLineCircleSlotRegular PolygonRectanglePolyline

1. Select Create from Cross-Section in the drop-down menu of Point.
2. Select the existing cross-section feature.

3. After completing the relevant settings, click on the cross-section line in the 3D scene to create; then click Confirm to create the new feature, and the object will be displayed in the feature module of the left-side tree view.

   Note

   When moving the cursor to the cross-section line, the feature point can be previewed in real-time; after creation, the feature point can be dragged on the current cross-section line to adjust its position.

1. Select From Cross-Section > Click on CAD section, Fit and Anchor in the drop-down menu of Line to open the corresponding window.

   • Click on the CAD section: After selecting the cross-section, click on the reference cross-section, and then define the feature as a reference feature or measured feature in the window.

   • Fit: After selecting the cross-section, click directly on the reference or measured cross-section, and then set whether to remove outliers in the window, and define the feature as a reference feature or measured feature.

   • Anchor: After selecting the cross-section, directly click on 2 points on the cross-section line and define the feature as reference feature or measurement feature.

2. Click Confirm to create the line feature, which will be displayed in the feature module of the left-side tree view.

1. Select From Cross-Section > Click on CAD section, Fit, or Anchor in the drop-down menu of Circle to open the corresponding window.

   • Click on the CAD section: After selecting the cross-section, click on the reference cross-section, and then define the feature as a reference feature or measured feature in the window.

   • Fit: After selecting the cross-section, click directly on the reference or measured cross-section, and then set whether to remove outliers in the window, and define the feature as a reference feature or measured feature.

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

2. Click Confirm to create the new feature, which will be displayed in the feature module of the left-side tree view.

1. Select From Cross-Section > Click on CAD section, Fit or Anchor in the drop-down menu of Slot to open the corresponding window.

   • Click on the CAD section: After selecting the cross-section, click on the reference cross-section, and then define the feature as a reference feature or measured feature in the window.

   • Fit: After selecting the cross-section, click directly on the reference or measured cross-section, and then set whether to remove outliers in the window, and define the feature as a reference feature or measured feature.

   • Anchor: After selecting the cross-section, click directly on 4 points along the cross-section line, and define the feature as a reference feature or measurement feature; the first 3 points determine the width and axial direction of the slot, while the last point determines the length and long axis direction of the slot.

2. Click Confirm to create the new feature, and the object will be displayed in the feature module of the left-side tree view.

1. In the dropdown list of regular polygons, 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 either a reference feature or a measurement feature in the window.
   • Fit: Select the cross-section, set the number of sides (3 ≤ x ≤ 8), then click directly on the reference or measurement cross-section, and set whether to exclude noise points in the window, defining the feature as either a reference feature or a measurement feature.

   • Anchor: Select the cross-section, set the number of sides (3 ≤ x ≤ 8), then click directly on the cross-section line to select 3 points, defining the feature as either a reference feature or a measurement feature.

     Note

     The three selected points cannot be collinear.

2. Click Confirm to create the new feature, and the object will be displayed in the feature module of the left-side tree view.

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 three selected points cannot be collinear.

2. Click Confirm to create the new feature, and the object will be displayed in the feature module of the left-side tree view.

1. Select Pick on the CAD Section in the drop-down menu of Polyline to open the corresponding window:

2. After selecting the cross-section, click directly on the cross-section.

   Note

   When creating polyline features, directly click on a curve to create; hold Ctrl and continuously select three points on a closed curve to create a local polyline; hold Ctrl and continuously select two points on a non-closed curve to create a local polyline.

3. Click Confirm to create the new feature, and the object will be displayed in the feature module of the left-side tree view.

Extract Measured Values

After creating reference features, the corresponding measured features can be extracted automatically or manually.

Note

Import at least one measured model before extracting measured features 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.

  Note

  If there are multiple measurement objects, please select the corresponding extraction object in the creation window; the default selection is the first measured model or the first measured model within the first measurement group.

• 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.

Note

When selecting sub-features, 2D features, or when there are only sub-features or 2D features in multiple selections or groups, right-click the feature group in the left tree view and select Extract Measured Feature to directly extract the measured feature without selecting a measured model.
