Assisted Feature Creation

Support assisted feature creation through CAD auto create.

Datum can be set after creating the feature:
You can right-click on that feature group in the left-side tree view and select Set as datum, and the created feature can be set as datum used for datum alignment or measuring parallelism or perpendicularity in GD & T.

Note

  • After enabling Auto Extract Measured Features in Setting > Feature at the top right corner, the software will automatically extract the corresponding measured feature after creating any reference feature.
  • After creating a feature, click in the right Properties panel to highlight the object in the left tree view and the 3D scene.
  • After creating a feature, you can edit the reference value in the right Properties panel, and the corresponding deviation value as well as the label will be updated in real time.

CAD Auto Create

Create features by directly clicking on the geometric features shaped as lines, single planes, circles, spheres, cones or cylinders of the CAD model.

Note

  • Before creating line 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 select the target feature in the Create Features toolbar first, and use the Pick on CAD Model method to automatically create features.

The steps for creating features through CAD Auto creation as well as extracting measured features are as follows:

  1. Select CAD Auto Create in the Assisted Feature Creation toolbar to enable the tool.
  2. Click on the highlighted geometric feature of the model in the 3D scene to create, and define the feature as Reference Feature.

  3. Click Confirm in the window of CAD Auto Create to save the reference geometric feature, and the reference geometric object ( point, line, plane, circle, sphere, cone, cylinder, etc.) 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 geometric 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 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 geometric feature; if you need to extract the cylinder feature, you can set fitting parameters, including constraint axis and constraint radium.
  6. The measured geometric feature object will be displayed in the corresponding geometric feature group in the left-side tree view.
