NX vs. Catia. How to do this?

[FrankMalone]

Hello all, there is a command in Catia I like to do en NX in a similar way.

Attached is a prt(NX6) and an avi file with the command in catia (2 selections and the command is done), in NX v.6 I neeed 4 commands to do the same thing.

Any idea to improve this action in NX.

Thanks.
Frank.

Managed to get it done to three. Still not as slick as catia in the situation.

Well I did it in 4 steps, but I think I can save you 2 steps which I suspect you had to perform before we got to where you passed us your example part, and if that's the case, then the net result will be the same:

4 steps - 2 steps = 2 steps

I say this because in your AVI showing the operation in Catia, I noted, as shown here...

...that it appeared that you created the two bodies using the Catia equivalent of the NX command 'Thicken Sheet', which indicates to me that these two bodies were originally sheet bodies (surfaces). Am I correct or not?

Look at the approach I took using NX 6.0, as seen in the attached part file.

Starting with the 2 sheet bodies, I performed 2 Trims, a Sew and then a Shell, for a total of 4 operations.

Let me know what you think of the approach which I took as compared to the OVERALL approach you took using Catia. I suspect that, if you're counting the steps needed, that we are basically at a wash here.

John's is probably the better lateral solution, but to more directly answer your question see the attached file.

In NX the idea of trimming two bodies to one another contains a tool and a target for the trim. One body or the other but not both will be affected and they don't boolean until you tell them to. It seems like a couple of extra steps but depending on what you're doing and what you're used to I guess you'll find it more or less agreeable.

So you don't need to do all those intersection solids and sneak up on the trim using subtractions.

You will need to keep and eye on how you pick what you're trimming to in the selection bar and in the case of your body I had to use single face selection.

The other thing to get used to in NX is that the geometry that is used to create each step is consumed by the change rather than kept but hidden so you've less by way of managing the data structure to worry about. Most NX users have never created an any booleans with "keep target" or "keep tool" turned on.

I don't know how has been created in Catia. I don't know how Catia works :-(.

This is from a customer who has Catia and has told to me that this command in Catia is very important for they. I am searching for solutions to minimize the impact in order to change Catia to NX.

Thanks
Frank.

I don't know how you created those original bodies. But if they were created as sheet bodies, you can trim and create a solid in a single command in NX. I used 'trim & extend' with make corner option. Trims the bodies and sews them together to make a solid.

See attached file.

That's actually quite Catia like. You have to work with sheets rather than solids to begin with but apart from that it has the advantage of providing the two trims in one feature which is so untypical of what NX users are familiar with that we'd tend to overlook it.

I have always been a little wary of the results of the extend part of trim and extend but apart from that and in this case I see no problems with that method. I would point out that the more usual approach would be to use solids as I described above but that goes more to the point of thinking like most NX users would.

You need another command to shell it inside. Did not see it initially working in shaded mode.

Still it is 2 commands.

Thank You guys for your comments and suggestions.

i want to know which one is better for an electrical engineer,unigraphics or catia.

As an 'Electrical Engineer', what is it that you will be 'engineering'? Both systems were basically developed for companies in the discrete manufacturing business, which generally includes most of what's manufactured in the world, but generally does not include GIS, AEC, ECAD, etc. However, a somewhat new area of design and manufacturing, Mechatronics, where aspects of both mechanical and electrical engineering and manufacturing are combined. This generally involves products which high electrical/electronic content, which includes much of what we consider as the consumer products area as well as, more and more, automotive and aerospace as well as medical equipment and even machinery.

Here are a few articles which might help you understand Mechatronics and how it may relate to your question:
