Using the Knowledge Inspector
The Knowledge Inspector allows you to query a design to determine and
preview the results of changing any parameters without committing themselves to
changing the design. This "what if" analysis provides immediate feedback that
helps you experiment and refine designs.
If it is important to determine what happens when one or more parameters are
changed, it is equally significant for you to see how a design can be changed
to achieve a desired result. The Knowledge Inspector supports this by allowing
you to query "how to" make a particular change.
In short, the Knowledge Inspector is a tool designed to study impacts and
dependencies.
What if
(impacts) |
Helps you understand to what extent changing any
parameter of your design (such as material, pressure, or a dimensional
parameter) changes the operation or design of the product on which you are
working. Can be used to examine interactions of parameters with each other
and with the rules that make up the product's specifications.
Geometric Update enables you to visualize the result of
your modification in the geometry area. |
How To
(dependencies) |
Helps you determine how your design can be changed to
achieve a desired result. |

The 'What If' Mode
 |
This task explains how to use the 'What If' mode. |
 |
-
Open the
KwrFormula1.CATPart document and access the Knowledge Advisor
workbench.
-
Click the Knowledge Inspector icon
or select the Knowledge Inspector from the standard toolbar. The
"Knowledge Inspector" dialog box is displayed. Check What If.
-
Select the KwrStartDocument\PartBody\Pad.1\FirstLimit\Length
parameter (at this stage, don't modify its value in the Equals field).
-
Click Apply. The following list of parameters
and parameter values is displayed in the Then area.
The first line describes the parameter which has been
selected. The other lines describe the impacted parameters.
-
Use the Equals field to replace the KwrStartDocument\PartBody\Pad.1\FirstLimit\Length
parameter value with 60mm. Click Apply. In the Then area,
the parameter values are updated as follows:
The InitialValue column shows the initial parameter
values (when you open the Knowledge Inspector). The OldValue column shows
the parameter values resulting from the previous 'What if' operation. The
Var (variations) columns show comparison operators between values located
in adjacent columns.
-
Check Geometric Update to display in the
geometry area the modifications resulting from the 'What If' operation.
Click Apply to update the document in the geometry area.
-
Click OK to apply the values resulting from
the current 'What If' operation to your document. Otherwise, click
Cancel>.
|
Note that:
- Using
reloads in the 'Then' area the previous or next values in the
history of the 'What if" operations.
|
- Checking Show All Parameters displays all the
document parameters. An f letter in the Dvn column
indicates that the parameter is constrained by a formula.
|
- Selecting a parameter in the Then area if the
Show All Parameters is checked, highlights the selected
parameter in the parameter list above.
|
|
|
|
Modifying a parameter value does not imply
that the values of the impacted parameters are automatically
updated by a 'What If' operation. For example, if a parameter is
constrained by a formula such as:
if Parameter1 > A then Parameter2 = B
replacing the Parameter1 value with a value greater than A
won't modify Parameter2 if Parameter2 was previously set
to B. |

 |
The 'How To' Mode
|
|
This task explains how to use the 'How To' mode. |
|
|
-
Open the
KwrFormula1.CATPart document.
-
Click the Knowledge Inspector icon
in the standard toolbar. The Knowledge Inspector dialog box is displayed.
Check How To. By default, only the parameters which are
constrained by a formula are displayed.
-
If need be, check the Show All Parameters to
display all the document parameters.
-
Select the KwrStartDocument\PartBody\Hole.1\Diameter
parameter (assuming that you would like to have this parameter
modified).
-
Click Apply or Enter. The list of
parameters to be modified to change the Hole.1\Diameter
parameter is displayed in the 'Use' area.
-
Select the Pad.1\FirstLimit\Length
parameter.
-
Check What If.
-
Modify the FirstLimit\Length
parameter in 'What If' mode.
-
Click OK to apply the parameter modification to your
document.
Note that:
- Checking Show All Parameters displays all the document
parameters. An f letter in the Dvn column indicates
that the parameter is constrained by a formula.
|
- Selecting a parameter in the 'Use' area if the Show All
Parameters is checked, highlights the selected parameter in the
parameter list above.
