Creating Spatial Groups

You can create a group of nodes, element edges, element faces, or elements using a bounding box.

1. To create a group in the GroupsGroups set, click Spatial Group in the Groups toolbar. To create a group under an existing mesh, right-click the mesh in the specification tree and select Create Group > Spatial Group.

   The Spatial Group dialog box appears.

2. Optional: In the Name box, modify the name of the group.

3. In the Mode list, select Box.

4. In the Type list, select one of the following:

   • Nodes to create a group of nodes.
   • Edges to create a group of element edges.
   • Faces to create a group of element faces.
   • Elements to create a group of elements.

   Important: It is not possible to change the type of group after you click Apply or OK.

5. Position the bounding box.

   1. Click the 3D shape to initialize the position of the bounding box.
   2. Move your cursor to specify the size of the bounding box.
      
      
   3. Click again when you are satisfied with the box size.

      The bounding box is displayed and the robot is automatically positioned at the selected location.
      
      

6. Use the sliders of the bounding box or the robot to modify and move the bounding box.

   
   
   

7. Click Apply to create and update the group.

8. Click OK.

   The box group is created and appears in the specification tree under the Groups set, and the bounding box disappears. If you created a group directly under an existing mesh, the group is stored under the mesh in the Nodes and Elements set.

You can create a group of nodes, element edges, element faces, or elements using a bounding sphere.

1. To create a group in the Groups set, click Spatial Group in the Groups toolbar. To create a group under an existing mesh, right-click the mesh in the specification tree and select Create Group > Spatial Group.

   The Spatial Group dialog box appears.

2. Optional: In the Name box, modify the name of the group.

3. In the Mode list, select Sphere.

4. In the Type list, select one of the following:

   • Nodes to create a group of nodes.
   • Edges to create a group of element edges.
   • Faces to create a group of element faces.
   • Elements to create a group of elements.

   Important: It is not possible to change the type of group after you click Apply or OK.

5. Position the bounding box.

   1. Click the 3D shape to initialize the position of the bounding sphere.
   2. Move your cursor to specify the diameter of the bounding sphere.
      
      
   3. Click again when you are satisfied with the sphere diameter.

      The bounding sphere is displayed and the robot is automatically positioned at the selected location.
      
      

6. Use the sliders of the bounding sphere or the robot to modify and move the bounding sphere.

7. Click Apply to create and update the group.

8. Click OK.

   The group is created and appears in the specification tree under the Groups set, and the bounding sphere disappears. If you created a group directly under an existing mesh, the group is stored under the mesh in the Nodes and Elements set.
