This task shows you how to compute
the mean dimensions of a part. |
|
You
must define the tolerances that you want before computing mean dimensions.
For more about tolerances, refer to CATIA-
Infrastructure User's guide Version 5. |
|
Open the Mean_Dimensions.CATPart
document. |
|
1. |
Before computing mean
dimensions, apply the Edit Parameters contextual command to Pad.1 to display
parameters, then take a look at the part you have just opened.
The part includes three toleranced parameters as shown below. |

|
|
Remember that to access tolerance values, you need to
double-click the parameter of interest, then use the Tolerance ->
Edit... contextual command. |
|
2. |
Click the Mean Dimensions icon .
A dialog box appears informing you that the operation is
performed. You then just need to update the part to observe the result. |
|
3. |
Click the Update icon
to integrate the modifications to the part. Note that the
update options set for your session (for more see General Settings)
do not affect the Mean Dimensions
command behavior: you
always have to explicitly update your part.
Mean dimensions are displayed around the part. |

|
|
Please bear in mind that if parameters are driven by
formulas, the application deactivates these formulas to compute mean dimensions. |
|
4. |
If you wish to go back
to the previous state, click the Mean Dimensions
icon
again.
A dialog box appears informing you that the part will be resized to
nominal dimensions. |
|
5. |
Click Ok to confirm.
An additional message appears to inform you that the operation is
performed and prompts you to update the part. |
|
6. |
Click Ok to close the
message window. |
|
7. |
Click the Update icon
to resize the part to nominal dimensions. |
