Figure 13: Constructing a Surface from Curves
Click on Curve 1.
PATRAN now anticipates that the next selection will be the Ending Curve. So without clicking
on the box marked ‘Ending Curve 2 List’
click on the Curve 2.
Leave the ‘Action’ at ‘Create’ and the ‘Object’ at ‘Surface’. Change the ‘Method’ to ‘Extrude’. The
form should be as shown in Figure 14:
Change the ‘Translation Vector’ to
0 20 0
Now this label should appear in the 2nd box. At this point without having to click on APPLY (because
AutoExcecute is SET) the 1st Surface will be created and displayed. The surface will be drawn in a
Green outline and its label will also be in Green.
Of course the conventional method of clicking on the boxes before making the selection still works.
Sometimes when mistakes are made use the ‘Undo’ icon and then follow the conventional method.
The next task is to create the second surface in a single step using the ‘Extrude Method’.
.
Figure 14: Constructing a Surface Using the Extrude Method
Click in the box marked ‘Curve List’ and click on the ‘Curve 2’. This should create and draw the
surface in Green and display its number (Surface 2).
The next task is to create the third surface in a single step.
Leave the ‘Action’ at ‘Create’ and the ‘Object’ at ‘Surface’. Change the ‘Method’ to ‘XYZ’. The
form should be as shown in Figure 15:
