This task shows how to use Path Finder
in interactive mode. Path Finder
is a functionality that lets you easily find the best path to dismount
assemblies. Two Path Finder
modes are available:
|
|
Before using Path Finder ,
you should have recorded a simulation. For more detailed information,
please refer to Recording a Simulation. Open
the
LABYRINTH.CATProduct document.
|
|
See
About Path Finder Messages for information about the messages Path Finder
provides and possible workarounds. |
|
Basic Path Finder Mode
|
|
-
Select Simulation.1 in the specification tree.
|
|
Repositioning the shuttle axis according to a potential
extraction direction eases the path finding process. |
-
Click Path Finder
from the DMU Check toolbar.
-
Keep the default settings:
Visualization: On
Steps: Medium
-
Click Apply to confirm your operation.
-
Click OK.
If you need to perform the smooth operation, select
Tools > Options > Digital Mockup > DMU Fitting, and select
the Automatic smooth check box. |
|
In terms of this scenario, Automatic smooth is not
absolutely necessary. However, the step below is included in
this procedure so that you can see how the command is used in
conjunction with Path Finder
. |
-
Click Smooth to
smooth the path result.
|
|
Advanced Path Finder Mode
|
|
Repeat the basic scenario above but select the
Advanced tab in the Path Finder
dialog box. |
|
-
On the Basic tab of the Path Finder dialog
box, select Advanced from the list for Steps.
|
The Advanced tab appears. |
-
Select the required values in the Path Finder dialog
box:
|
The table below provides an explanation of the fields in the
Advanced tab of the dialog box.
Field |
Possible Values |
Explanation |
Environment |
Smallest Detail |
Enter amount |
Accuracy used to calculate the environment description. If
you enter a small value as smallest detail, the environment
description will be very accurate but very costly in terms of
memory size.
If you enter a big value, the description will be coarser
(e.g., if the diameter of a hole is smaller than the value
entered, the hole no longer exists as it is filled with matter).
In this case, you gain in memory size. |
Repulse effect |
Low
Medium
High |
The higher the repulse effect, the smoother the
path and the more the rotation motion is eased . |
Bounding box |
Environment |
Creates a bounding box around the data (default). |
Path |
Creates a box around the path only. |
Custom |
Enables you to alter the bounding box size (if you alter the
size without selecting Custom, Custom is automatically selected). |
Motion |
Translation step |
Enter amount |
Unit used to define the step value in translation mode. |
Rotation gain |
Use arrows to alter amount |
Linked to the translation step parameter, e.g.,
- If rotation gain value = 2, the rotation amplitude =
2 x translation step value
- If rotation gain value = 0.5, the rotation amplitude = 0.5
x translation step value
|
Apply to part of the track
|
-
When you select this check box, you
will be prompted to select a beginning and end segment of the
track that will define the area of the track to which you want
to apply Path Finder .
-
When you clear this check box (the
default). Path Finder
applies to the entire path.
|
|
-
Click Apply.
-
When done, click OK.
-
Replay the simulation.
|
|
Be careful not to choose values which are not compatible
with your model.
For instance, here if you enter 30mm as Translation step value,
the moving object will jump over the glass material because the path is
already considered out of collision, which is not true. The following
information message is displayed:
