Exercise: Changing the Shape of the B-pillar with the Help of Morph Volume
This exercise shows how to smoothly change the shape of a B-pillar via morph volumes.
Figure 1: B-Pillar before and after morphing
Step 1: Load and review the model.
Open the HyperMesh file, body_side.hm.
Step 2: Create morph volumes.
1. Access the morph volumes > create sub-panel in one of the following ways:
x From the Morphing menu point to Create and select Morph Volumes
x On the Tool page, select HyperMorph, then morph volumes
2. Switch the creation method to pick on screen.
3. For handle placement, select corners only.
4. Keep the auto-tangent check box selected.
5. Draw a window by clicking at the four places shown in Figure 2.
Figure 2: Points for creating the morph volume
Note: A morph volume is created, enclosing the area.
Step 3: Split the morph volumes.
1. Access the Morph volumes > split/combine sub-panel in one of the following ways:
x From the Morphing menu point to create and select Morph Volumes, then select split/combine
x On the Tool page, select HyperMorph, then morph volumes, then select split/combine
2. Verify the split toggle is set to split mvols : by edges
3. Select an edge of the morph volume close to location 1(Figure 3).
Figure 3: Locations to split the morph volume
The green colored cross moves to the location of the black dot.
4. Click split.
The morph volume is split into two. Follow the same steps to create another split at location2.
Step 4: Change the profile of the b-pillar.
1. Access the morph > move handles sub-panel in one of the following ways:
x On the Morphing menu point to Morph and select move handles
x On the Tool page, go to HyperMorph, then morph, then select move handles
2. Set the morphing method to translate.
3. For direction use along X, Y, Z.
4. Key in the following values:
5. Select the eight handles by window as shown in Figure 4.

6. Click morph.
Rotate the model to observe that the b-pillar is morphed.
The b-pillar is morphed in a smooth fashion with minimum distortion to the elements.
