Step-by-Step ScenarioTop

Insert  the KIN_EX17* .model files from samples folder.They are to be found in online\kinug_*X2\samples

If you work with the Cache System, make sure you are in Design mode (select Edit > Representations > Design Mode.). For more detailed information, refer to the DMU Navigator user's Guide - Task: Viewing the Cache Content.

The following task shows how kinematics data is pasted from an existing Version 4 model to an existing Version 5 document alongside V5  data. You can of course also insert the V4 data into a new Version 5 document.

  1. Open the model containing the kinematics mechanism.

    Open the Kinematics Simulator workbench if necessary.

    The model containing the kinematics mechanism should only be a stick model (that is, wireframe plus the definition of the mechanism).

  2. In the specification tree or in the geometry area where the Version 4 kinematics model is displayed, select the mechanism you wish to copy into the Kinematics Simulator Version 5. In our example, select KIN_EX_00_F1_ACTIVE and LANDING GEAR.

  3. You can also use the drag & drop capability.

  4. Put the data you have selected in the clipboard. To do this, either click the Copy icon, select the Edit > Copy command or select the Copy command in the contextual menu.

  5. Select Application in the specification tree.

  6. Now either click the Paste icon, select the Edit > Paste command or select the Paste command in the contextual menu.
    This operation recovers the data previously put in the clipboard

You may want to click Fit All In I_ReframeP2.gif (216 bytes) to fit all data in the window.

The dressup is maintained when you perform a copy/paste within the same document.

Notice that the toolbars change depending on whether a Version 4 model or a DMU Kinematics Version 5 document is selected.

The result should look something like this:

V4 laws are converted in a V5 mechanism.


Kinematics Simulator fully supports V4 mechanisms (2D/3D) conversion into 3D mechanisms 
version 5.
Note: Limits cannot be converted from V4 to V5.

What About the Elements You Convert?Top

To make sure the elements you need to handle in your session are those you expected, here is a list presenting the CATIA V4 Kinematics data supported when converted  into a Kinematics Version 5 document:
