Blocking Select Blocking > Create Block > Initialize Block . Choose 3D Bounding Box from the Type pull down if not already set. Enter FLUID in the Part name, and make sure Orient to geometry is OFF. Press Apply to initialize the first block around everything.

Figure 3-181 Initialize Block Window

Note: If nothing is selected in the entities window. Then by default it takes all the entities.

To achieve the "L"-shaped blocking topology shape for the elbow, the user will make two block splits and discard a block. Deleting a block without "permanently" checked will only move the block to VORFN.

Turn ON Curves from the Display Tree and select Blocking > Split Block > Split Block to open the window shown below. The Split method should be set as Screen select by default. Create splits as shown below by selecting any edge that you want the split to run perpendicular through. Press Apply, and then select a location for the split to run through, and press the middle mouse button to accept. Make two splits as shown in the figure below.

Next, select Blocking > Delete Block , and select the block shown highlighted below. Delete permanently should be turned OFF, then press Apply.
