Anybody knows an actual test which compares the performance of different CAD programs like I-deas, NX 2, Solid Edge V15 and Catia V5?

Today we are using I-deas NX and testing Unigraphics NX 2.

When we change to another system the iterative design improvement process on _(complex) 3D objects_ shall be more efficient (quick, easy). The rest of I-deas is very fine.

Thank you for hints! (deutsch oder/or english)

Regards
Harald

I had I-deas four years ago and I hate it. This was because I could not handle their overloaded file managing system. IMHO the functionality had little more features then SWX but it was not build the way I use to think.
Today I allways add 30% extra time if I had to import data from this system via any neutral format. (maybe itŽs fault of my client and not caused in I-deas)
I love the simple, easy to use SWX even when I think the development of SWX is going the wrong way. (Too many needless knick-knack instead of stability, stability, stability and performance)
As you wrote the rest of I-deas is very fine you should forget SWX, because the way of thinking is too easy for you. I canŽt tell you anything about speed comparison. You have to compare by yourself.

I love I-deas' TDM (design management). But may be I would love Solid Edges Rapid Blue 3D (design feature) even more.

More detailled information about our problems:
I am not satisfied with the stability and performance of the algorithms of I-deas NX and NX 2 when changing draft angles, rounds, fillets, lofts, ...

Problems arise when the optical design of a part is ready and it is then necessary to change geometry add draft angles, ... for diecasting or plasic injection purposes. In most cases it is necessary to rebuild many of the rounds, fillets, ...

I have no idea if Solid Works has a better performance and stability in this area.

Harald,

I am making plastic injection tools with SWX. You cannot change the draft of a wall when there are fillets on one or both ends. But with both systems it should be no problem to add a dreaft feature one step in front of the filltes, or you change the feature creating the wall direkt to the desired angle. With SWX the fillets are "walking" with the draft. Stability and performence are no problems in this matter, of course the mold-cavity features could work faster 

The problems I allways have is the imported data. ItŽs real work to kill the fillets, add draft and rebuilt the fillets.
My special problem with the I-deas client is, there are no right angles. Every surface has 0,0000032º error in angle, often in differest directions. This is hard if you are used to fix the parts with congruent surfaces.

this is exact one of the points where problems often occur. I-deas and NX 2 think that there are some impossibilities (which is wrong in many cases) or just do nothing.
I first trial with Catia V5 today showed less problems in this respect.

I saw such a problem in I-deas but extremely seldom. My be it is dependant on the version.
