Modifying a feature

Each part is defined by a set of features, and each feature in turn is defined by a set of parameters. For example, the base feature (the cube) and the second feature (the flange) are both defined by a sketch and an extrusion depth. You modify a part by modifying the parameters that define its features. For the hinge example you will change the radius of the hole in the sketch of the flange from 0.01 m to 0.012 m.

  1. In the Model Tree, expand the Hinge-hole item underneath the Parts container. Then expand the Features container that appears.

    A list showing each feature's Name appears. In this example you have created two solid extrusion features: the base feature (the cube), Solid extrude-1, and the flange, Solid extrude-2.

  2. Click mouse button 3 on Solid extrude-2 (the flange) in this list.

    Abaqus/CAE highlights the selected feature in the viewport.

  3. From the menu that appears, select Edit.

    Abaqus/CAE displays the feature editor. For an extruded solid you can change the extrusion depth, the twist or draft (if specified when the feature was created), and the profile sketch.

  4. From the feature editor, click .

    Abaqus/CAE displays the sketch of the second feature, and the feature editor disappears.

  5. From the edit tools in the Sketcher toolbox, select the edit dimension value tool .
  6. Select the radial dimension of the circle (0.010).
  7. In the Edit Dimension dialog box, type a new radius of 0.012 and click OK.

    Abaqus/CAE closes the dialog box and changes the radius of the circle in the sketch only.

  8. Click mouse button 2 to exit the edit dimension value tool. Click mouse button 2 again to exit the Sketcher.

    Abaqus/CAE again displays the feature editor.

  9. Click OK to regenerate the flange with the modified radius and to exit the feature editor.

    The flange hole is enlarged to the new radius dimension.

    Note:

    In some circumstances regenerating a feature causes dependent features to fail. In such a case Abaqus/CAE asks if you want to save your changes and suppress the features that failed to regenerate, or if you want to revert to the unmodified feature and lose your changes.
