Hello,

I just finished CATIA classes here in Wichita KS at WSU and I find this forum to be very informative. I hope after I get more experience I will be able to help out too.

 

Now to my first question. Is there anyway to export a body out in a different coordinate system? I know how to create axis systems I would just like to be able to export the part in relation to this axis sytem without the axis to axis translate.

 

Thank You,

Kevin C.

Kevin,

 

You can do this several ways

 

1. paste special, as result.

 

One is to do the axis to axis, copy the body, make a new cat part and paste special, as result.

 

2. Another is catpart from product,

Make a product, add the part, move it where you want, and go tools make catpart from product. This is also handy if you have several instances of ... say a clamp, and you want to output them after moving them with assy tools.

 

Hope this helps.

 

By the way, I like your thinking. For you to say " I hope after I get more experience I will be able to help out too."..... That is what COE and the forum is all about.

 

Welcome

 

Anyway, I am sure there are other ways, and I am a MFG, guy, so others in time will offer more complete and better methods, I’m sure.

Hey Dave,
Thanks for the welcome and the answer. I am not sure I worded my question clearly. What I really want to do is to leave a model in it's original (airplane coordinates) create the neccesary machining coordinate sytems around the part to machine it without moving the part at all, but then I would like to be able to export the model in STL format in relation to each of these created coordinate systems so then I can run a backplotter (kind of like vericut) on the G-code to watch for errors in the program the STL is located correctl for the new zero point. Doing what you suggested above still exports the part in relation to the original coordinate system.

Thanks again ,

Kevin C.

Personally I'd do the following,

1. Create a linked copy of the design part

2. Put an oriented bounding box around it (In AMG or GSD or Core & Cavity)

3. Put an axis system in the middle of your BBox

4. Create an assembly

5. Create a new part in the assy (usually a stock)

6. Fix the stock

7. Constrain the design part to the stock (axis systems)

This now enables you to "Generate Catpart from CATProduct", do this then save the new part as a STL. Plus it allows you to edit the design part, if needed for machining purposes, without altering the original

Variations on the same theme will give you similar results.

Thanks Dave,
Why didn't I think of that?

Have a good one.

Well I guess we don't have the license for the bounding box function. we have the Generative Surface Design and Generative Sheetmetal Design workbenches but I can't find the bounding box function anywhere. I looked through the list of all command and it was not in there.

I guess I can just continue to do the axis to axis translate to export my STL in machining coordinates.

Thanks to Dave and Dave.

Check this link out.  http://www.coe.org/Collaboration/DiscussionForum/ActiveDiscussions/tabid/210/view/topic/forumid/6/postid/123523/Default.aspx

The method I posted is what I use to export STL or STEP data with a specific axis without moving the original data or mess around with translations, rotations, and such.

Phil Barna also posted an excellent method.

Thanks Gary,
I will give that a try on my next part. I bookmarked that excellent thread.

The bounding box is available if you have a machining license and can be found in GSD under the surface machining toolbar

Thanks Dave,
We do have the machining workbench. We have the Prismatic and Surface Machining but we don't have the Advanced Machining workbench. When you say GSD you mean the Generative Surface Design workbench correct? We do have that but I didn't see the bounding box function but I didn't look under the surface machining tools.

Also another question is the analyze function where you compare your cut part to the model. Is that not usually included with the prismatic and surface machining workbenches? Because I don't have it now and our reseller is wanting a pretty penny for it. I got so used to that at school and it saved me alot of times I am not sure I would want to run without it. This would probably a question better asked in the MFG forum though.

Thanks to everyone who helped. Hopefully I will have some time to try this stuff tomorrow.

Yeah, you'd get better responses in the MFG forum.

Dassault set what functions come with which licenses and i'm pretty sure that the analyse function doesn't come with your LPE & SGE licenses, you'd have to get AME ($$$$$) or NVX ($$$)

NVX is an extension whereas LPE, SGE, MME & AME are enablers. At least one enabler is required in order to be able to purchase an extension...


I think :S

I will just add that I have purchased the PLM express version of Catia because this "Analyze" function in Video replay and also Multi-Pocket and Prismatic assistant licences come for free with it...at least when you purchase advanced machining.

Well we ended up calling our reseller and we upgraded our license I think to the PLM express so now we will have the analyze funtion. He said something about going from IBM to Dassault for our licensing now, I guess the pricing is a little better? The package they are adding is the NVX whatever that means. I feel like I am driving 90 miles an hour without a seat belt when programming without this function.

Thanks guys,

A couple posts mentioned a "bounding box" - is that the same thing as the ROUGH STOCK command?

Good question Jack,
I was wondering the same thing. I don't have the bounding box function but I do have the rough stock option.

The "bounding box" I'm familar with is the white box that shows up when you measure the inertia of a part. Saving the measure adds the origin and length parameters of the white bounding box in the tree.

I don't remember, but I'm guessing the Rough Stock command creates the same information. It just represents it as surface geometry in a Geom Set.

Rough stock is different to bounding box. Rough stock makes an offset mesh
