Switching to UNIGRAPHICS?

Yeah, I love the guy who said to fake it and just use cm. That will work well in downstream applications.

That is the beauty of relative accuracy, 0.1 x 0.1 micron part is no problem.

Hi Guys
In fact, I checked Catia, UGNX4~6, Solidworks, Solidedge, VX, Vero Visi, Inventor etc etc. Normally, the main thing is that which tool (software) you can use more easily and in which you are more expert. Every one has his own opinon. In my opion, the main thing is designing. More easily and powerfull designing options you have, more comfortable you are. There are a lot of people in the world that are using MasterCAM for machinig. Some loves feature of Powermill. Most people says that Pro/Man doesnt gives satisfactory results. I am using it from last 8 years and I get results as I like a lot of times.
What is the main problem that we must know how to use the tool properly and thats all. I had designed a lot of molds on AutoCAD 12~2000 before start using Pro/E. But now, I cant use it anymore. I saw a person design a very complex mold in MasterCAM. Immagine,

can you believe that you can make a mold in MasterCAM. Not now, its almost 8 years old story. At that times MasterCAM was supporting only surface modeling, and tools are the worst ever.
In my opinion, Catia is no 1 in surface modeling, where very complex surfaces are involved. In solid modeling, mold designing, assembly modeling, drafting, sketching Pro/E is no 1. If you are only in designing field, now a days, Inventor is best for part and assy modeling with drafting.

Designing what exactly?

 

[Kaeliz]

I've worked in UG since the beginning. When I started on it in 1982, it was a 2-D computer drawing board.

Now, I do whole tool/fixture assemblies in it. I primarily work in tool design, inserted milling cutters being my speciality. With a touch of forethought, you can make a 3-D model and assembly of components that is fully parametric.


IE: I can change 3 parameters in one file and everything in files up and down the assembly structure update. Even the drawing updates to correct data.


I'm not putting down any other modeling software, just saying UG, when used with forethought, is a VERY powerful modeling system.

Thanks Kaeliz

Unfortunately,this kind of experience missing me.But is a good point to start

Can i have some example?

Thaks again

I also agree with Zaki.
If you need to schetch something very complex in 2D Autocad is probably the most powerfull tools.
I have some friends involved in lots of arts project (imagine some images on coins)
Others need some sketches tu use different chemichal methods (corosion)on the sheet metals and most simple to do is to create a 2D parametric model in Autocad

 

[kanishk]

both have their own strengths and weaknesses.
For core parametric feature based modeling ,i would prefer Pro/Engineer over any other CAD package.The modeling philosophy of Pro/Engineer is ultimate,i really like the way the tools are arranged and how they can interoperate providing unmatched depth of functionality.
On the other hand UG has plethora of tools that don't quite work in concert.
While Pro/Engineer may be the best modeler on earth,UG is a bit better as far as surfacing is concerned,but interface sucks.
Also Advanced Simulation of NX with its primary solver as NASTRAN outweighs pro/mechanica.NASTRAN gives much better control over meshing and Its more robust too.
Flexible Body Simulation in NX is one such improvement which makes it a Fine Multibody Solver too.Pro/Mechanica isn't near around yet.
One more advantage NX offers you is seamless integration between simulation and modeler.In simulation you can perform varied things-even pretty cool CFD.therefore,U need not learn some other software for CFD unless you are that much into it(openfoam is a nice choice then

)
But all of these modules show up on costs and UG is not the cheapest as you might be knowing.
In nut shell,nobody is clear winner,It depends more on your Industry.

I think the Sketcher tools of UG could use a fresh redesign from a UI expert.
