Reworking a 3D Shape

Associative Part Design Feature Recognition enables you to modify locally a 3D shape by removing faces and redefining features from these faces. It enables quick associative modifications of a complex 3D shape without having to find out the localization of the previous specifications in the design tree.

It can be a way to change locally the specifications of the 3D shape. You can:

For example, as shown in the first scenario, if you have a pattern of holes and want to edit only one or two holes out of it, then you can re-specify that hole with Part Rework. The new hole definition is available if you want to edit it.

Part Rework is shown in manual mode in this task but it is also available in local feature recognition mode.

This task shows you how to:

Rework On a 3D Shape Using Manual Feature Recognition Command

You can rework on a 3D shape using the Manual Feature Recognition command.

  1. From the Recognize section of the action bar, click Manual Feature Recognition
    The Feature Recognition dialog box appears .
  2. In this scenario we will break dependency of circular pattern of holes, so that one hole can be edited without affecting other holes in the pattern. To use Feature Recognition as Part Rework, just select the Both option at the bottom of the dialog.
    Apart from isolated solid, Manual Feature Recognition can also be applied to rework a 3D shape to any 3D shape design feature as In Work Object. When any 3D shape design feature is in Work Object and not an isolated solid, then Feature Creation Options is by default set to Both i.e. for Part Rework mode.
  3. Select Hole in the dialog box and select the required face of the hole.
  4. Click OK to confirm the operation.

    RemoveFace.1 and Hole.2 features are created.

    This newly defined holes can be edited without affecting other holes in the pattern.

    Now, if you want to get original tree, you can easily get it by deleting RemoveFace.1 and Hole.2. Thus the capability ensures that you obtain desired results without changing the original tree.

Break Face Continuity

Part Rework can even be used to break face continuity.

Before you begin:

To perform the scenario, create a pad (from a rectangle including a corner) as shown here.



If you try to draft the yellow face, then the green face and blue fillet face will also get drafted with the same angle value, because of tangency. So if you want to draft these two faces with different angles, it is not possible with this tree, but Part Rework makes it possible .

  1. Click Manual Feature Recognition .
  2. First recognize the blue fillet. To do so, select Fillet in the dialog box and select the blue fillet.
  3. Check the Both option at the bottom of the dialog.
  4. Click OK to confirm the operation.
    RemoveFace.1 and EdgeFillet.1 features are created.
  5. Now set RemoveFace.1 as In Work Object and then draft the two (yellow and green) faces with different angles as desired and then again set EdgeFillet.1 as In Work Object, you will obtain the desired results.
