This task shows you how to create a rough offset surface, that is a
constant offset surface which approximates the initial surface to keep only
its main characteristics. |
 |
Open the RoughOffset1.CATPart
document. |
 |
-
Click Rough Offset
 .
| The Rough Offset Surface Definition dialog box appears. |
 |
-
Select the Surface to be offset.
| An arrow indicates the proposed direction for the offset. Click
it to reverse the direction. |
-
Specify 20mm as the Offset value.
-
Set the approximation tolerance by specifying 1mm as the
Deviation value.
| The default and minimum value is 1mm. |
-
Click Preview
to preview the offset surface.
| The offset surface is displayed normal to the reference surface.
|
 |
|
A progress bar is displayed to allow the control of
the computation. |
 |
-
Click OK to create the surface.
| The surface (identified as Offset.xxx) is added to the
specification tree. |
 |
|
Note that the boundaries of the rough offset
surface are not computed. Only a global boundary that contains one
sub-element is created. |
- You can display the offset surface on the other side of the
reference surface by clicking either the arrow or Reverse
Direction.
- You can generate two offset surfaces, one on each side of the
reference surface, by checking Both sides.

|
In case an error message is issued
asking you to modify the inputs, we advise you to change the deviation,
either by increasing or decreasing it. |
