How to create multiple models

[fighterpilot]

I have a sheetmetal part where I've included unfolding operations to show how the part is manufactured. I'd like to create a model of each operation for a demo. In my Pro/E days I would have simply created a Family Table and put the Unfold feature in the table and turned it on/off in the model I needed it to be in.

How do I accomplish this task in Catia. Catalogs?, etc?

Thanks....

You would do this in a design table. You can input multiple configurations, and update them simply by selecting them from the list. When you want more configurations, they can be manually added into the design table, (either a plain text file, or excel spreadsheet) and then updated through the relations parameter in the tree.

That's what I was thinking now that I look back thru my Knowledgeware books. Is each model treated as a separete (sp?) model or is it a modification to a master that retains a link back to the master?

Thanks...

No, it's all the same model, and whatever configuration is active, defines the whole thing. You can copy the model and design table, if you choose. (for multiple models)

Of course, you can always isolate each configuration as you make it, or export it as a neutral format, if you want to "lock" the configuration.

If you would like help making a design table, contact me through the link on my signature.

Ok, let me get this straight. Option 1 model defines one bend and option 2 model defines another configuration. If a feature, such as a hole, is common to both and I modify the hole, will the modifcation show up in all models?

Or, if I have an assembly, can I assemble in all the various option models?

That starts to get even trickier. You would have to start using some knowledgeware to start turning features on and off based on parameters in your Design Table.

Jim,

Yes, I'm thinking KW to turn features on/off based upon a certain configuration. I need to know that I will get 4 separete models to assemble into my assembly yet they are all linked to a master.

In the past I did the following in the competition's software.

Master Model 1
Option 1A (feature X on)
Option 1B (feature X and Y on)
Option 1C (feature X and Y and Z on)

Now in assembly Assemble Model 1, it asks for what version. Select model Option 1A. Assemble another Model 1, again what version. Select 2A. etc...

In the BOM I'll get:

Assy
Option 1A
Option 1B
Option 1C

Where each option model is still tied to the Master Model 1.

First off - if you have an "option" defined in a design table, you will basically have a row of data, corresponding to your parameter heading.

That is to say, if the diameter of your hole is defined, and in Row 1, is assigned a value of 2mm, and you wanted a new "configuration" with only a change in this diameter, you would start Row 2 by copying all of the existing parameter, and change the value of ONLY what you wanted changed. (in this case, change the 2mm diameter to something else, like 3mm)

Now, you just have to pick the appropriate Row of values in the design table. (by calling up the design table in the relations)

You can go through each Row of values, select them, and update the assembly. (or it will do it automatically if you have auto updates selected)

Again, if you want to see a "locked" configuration, select the Row of values that you want, and pull a dumb solid, or save a neutral format.

You don't get all of those fancy BOM options like this, though. That's advanced stuff. It's easier, in that case, to do it with multiple parts. (or so I think - mabye someone else has a better way)
