Selecting Multiple Surfaces

You can select multiple surfaces and perform modification.

This task shows you how to:

Before you begin: Create a 3D shape containing two subdivision surfaces.

Modify multiple surfaces

You can select several surfaces to modify them.

  1. Click Translation .

  2. Move the mouse cursor to highlight the desired axis or plane.

  3. Hold down the left-mouse button and drag to translate the surfaces.

  4. Release the left-mouse button when you are satisfied with the new position of the surfaces.



Use one subdivision surface to modify another

You can select a surface in order to modify another one.

  1. Click Compass Definition again.

  2. Click Alignment .

  3. Select the multiple edges or vertices on the first subdivision surface to be aligned onto the second subdivision surface.

    Tip: You can use the Ctrl key to multi-select the faces, as well as adding, removing, modifying the selected faces.



  4. Click on the manipulator to project the edges.



    You can see that the edges are projected:



    The result is the following:



Important:
  • All modification commands can be applied to multiple surfaces.
  • When you work with more than one subdivision surface, and if the Working Zone command is activated (or deactivated), then it will be activated (or deactivated) for the entire selected subdivision surfaces.
  • If you have selected faces, edges or vertices of a subdivision surface and further deselected the subdivision surface, reselecting this subdivision surface will highlight all previously selected elements.

Smart Selection of Multiple Surfaces

In case a feature has more than one parent, you can select and modify the required subdivision surfaces using the Crtl key.

Here is the example we use for this scenario:



Using the Parents/Children... contextual menu item, you can see that the edge fillet feature (EdgeFillet.1) has the three subdivision surfaces as parents.

  1. Select EdgeFillet.1 and click Modification .

    You can see that all the parent subdivision surfaces are highlighted in the specification tree. A Tools Palette also appears.

  2. Press Ctrl key and select the parent subdivision surfaces you want to modify. In this case select Subdivision Surface.1 and Subdivision Surface.2.

  3. Click Apply in the Tools Palette to validate the selection. You can see that the selected subdivision surfaces can now be modified.



Important: If the Ctrl key is not pressed and you select a surface in geometry, the modification of the selected surface starts without any validation.
