Exactly, Except for Imageware(to my experience), UGS provides acceptable pro level support. I also like Delcam guys. They have a helpful user forum being monitored by their support team and normally you get immediate response and a solution for your problem from them and it's free of charge...

rkhan, Thank you very much for your concise note. Very much helpful. I personally have started looking into R17 closely. Do you have any experience with ICEM Shape Design? Anyway, Thanks all and a happy new year everybody. Car Designer

And also a much better customer support and much flexible options to choose from. Car Designer

Acis is from Spatial(owned by DS) and Parasolid is from UGS and others are licencing the use of the two's kernels. Only two majar suppliers for core modeling engine. No other competitor in that level (maybe PTC and Autodesk can do it in future) to introduce new innovative features and a much...

For the high-end CAD users choices are very few. DS and UGS are the dominant vendors and almost all the other vendors are using either ACIS or Parasolid or both (except few who may use Granite or those from Think3 and Autodesk). Since you have not much choices, naturally you have to adopt those...

Jackk, Technical surfacing needs that the modeler knows exactly about the parametrization and approximating methods and the results of the chosen degrees and spans of the curves and surfaces of the model. Yeh you need to have a deep understanding of your construction curves as well as taking the...

Since only those two big boys are on the playground high-end CAD market lacking the much needed competition between innovative CAD vendors and more options as a result. I hope someday someone rise the bar. Car Designer

Hi guys, I didn't read all the posts here though it seems some good explanations have been given. From my perspective(I don't think much about the definitions for so-called class-A surfaces)what I am concerned is the high quality technical surfacing and techniques to produce manufacturable...

It's not fair that customers are being forced to move into each new releases by CAD vendors even if you don't need those extra functionalities. Vendors must follow what their customers demand and they have to convince customers to pay for what they need. Car Designer

catiajim That's it. I was questioning about the workbenches I mentioned in my posts. Other modules for CAM, CAE, etc, are not my concerns at the moment. Car Designer

itsmyjob What platform are you using? I am still on R16 and the SP3 just has been released for R17. I will ask those guys working with R17 if they've found and reported anything not mentioned by IBM. I myself will wait till SP6 or 7 before doing any serious job by R17 entirely. Car Designer

Solid7, I have here FreeStyle and Class A, also the best of surface modelers (Alis, Icem and Imageware)here and I still keep Rhino. In my job meeting class A surface standards and matching all those tolerance required for high-end packages is an everyday part of the job. Please don't worry about...

catiajim Hi Did you mean the R14 (currently SP10 is there for it) is more stable than R15 and 16 (with sp7 and 8 respectively)? Are they still supporting R14? I mean they will do bug fixing for it as with any more SP in 2007? All those damn bugs! I hate them. At least NXs are better in that...

It's not the matter of the cost or licensing, that is the business of the company owners. As for what I am concerned and designing and my quality policy any move to a newer version should be justified by the added features and enhancements, performance improvement and stability tests after a...

solid7 I was clear. I ask for a professional advice. I am running both R15 and R16 together on XPs. And really if there is any considerable improvements in the two WBs I mentioned I would consider a half working day loose to back-up all the current jobs and add 17 to our primary workstations...

DBezaire, I just want to know if there is anyone familiar with the two workbenches I mentioned in the two releases who don't mind gives his/her findings regarding the enhancements or any useful added features to these two WBs only from a practical point of view concerning freeform modeling and...

Hi there, As for product design and surface modeling, would the enhancements in R17 justify an upgrade from R16? Anybody using Free Style and Automotive Class A WB extensively in the two releases? Thanks in advance. Car Designer

Thanks JuhanEdag, At last it would be Shape Design from ICEM for Catia as I heard. It would be interesting to see how experienced ICEM Surf users feel about it. I would like to start a group for technical and class-A surfacers. Any feedback is highly appreciated. Car Designer

They all have been loaded and during installation from the original CDs there is no ACA in the list whether can be choosed or ignored. In the product itself (P3 V5 R16) I have all and they are available as previous releases but no ducumentation related to ACA. Maybe they first ditched its...

The problem is that there is nothing as Automotive Class A under Shape Design as in R14 but all other products are there as FreeStyle, Generative Shape Design, etc. I can send two print screen images of both to show the deference. What I would like to know is that if it is same for others who...
