PROE vs Unigraphics vs Solidwoeks vs Catia
(OP)
I m a Design Engineer.Our company wanted to buy a new Software so which one is better PROE or Unigraphics or Solid works or Catia.Currently we r using Mechanical Desktop , Pro E 2000 i.

RE: PROE vs Unigraphics vs Solidwoeks vs Catia
ProEngineer is far to constricting of a tool. It is very common to design yourself into a corner using ProEngineer. This waists a lot of time and effort. ProEngineer is known for being too difficult to use. CATIA V5 is a good tool but it is far to unstable and not even close to the capability of Unigraphics. It has been developed for over four years and is still not production ready. You can ask many of the large companies using it that question. I know many companies reverting back to CATIA V4 (which is like working back in the stone ages) because CATIA V5 can not do their job. I have not used SolidWorks. I know many people who like it but I would tend to stay away from it because is does not scale at all to the growth of your company. In my honest opinion, Unigraphics is head over heals the best CAD solution available.

1mm depth of ocean water(my info of each package), spacially in modeling.
I think high level softwares(ug-catia-peo_e) aresimilar to a very old and experienced man that consider any option for doing a job, so speed reduces and accuracy and abilities increse.
but midrange softwares such as mdt-solid edge and work and cadds are similar to a younhg man that with less options in consideration does its job.
this is in modeling(regardless of less modules such as sheetmetal, routing, ...).
A big company needs a high level software to do all designing, calculating, and manufacturing its product in only one software beacuse of associativities between objects and modules, ability, accuracy, not data transfering, least files(data jungle with less trees in design to manufacturing process) and ...

So, I went to his office and explained him where the problems are since we have to do around 20 molds for him.
He explained that in Pro-E for adding draft in a surface you have to go after extrusion and add it on each surface. Than I understand why he do not add draft, adding draft in injection molded parts in Pro-E is a big pain when you dealt with parts that have 40-50 extrusions and each extrusion has at least 4 surfaces, can you imagine what a lost of time is for a designer of plastic molded parts to design in pro-e, even if there are slight advantages in other areas. Only for that reason we discarded the otipn to go to Pro-E since I-deas is going to desappear. I think the best in the market today are Catia V5 and UG NX.

Your Pro/E guy doesn't know how to use Pro/E if he says draft has to be applied to individual surfaces. Pro/E Wildfire can take a non-planer parting line and apply draft in both directions.

Could he have meant draft has to be applied as an individual feature, unlike in UG where it is part of the extrusion?

RE: PROE vs Unigraphics vs Solidwoeks vs Catia
The draft is applied as a feature after the basic part is modeled. But it can be applied to the whole model. Since I don't do plastic injection molds, maybe I am missing something when it comes to applying draft to the model. I would think that you would apply the same draft angle to all perpendicular surfaces to the parting line.

In injected molded parts draft is not the same in all the surfaces. Where you have shoot-offs you nedd more draft than in a surface that do not have shoot-offs.
But I think even during design process you have to be carefull because your part is design in a assambly envoirement, so you need to keep the relations(clereances) from the other parts.
Another problem is within the part itself. Lef assume that you extrude a square 1"x1" in .500" height, than you scetch on the top face and draw a circle .25" diameter which you constaint with a dimension .300" from one edge and .400" from the other edge and than you extrude it by.500". Since you do not have draft on the first square extrusion you need to add it after, my question is what happend with the round protrusion when draft of 3 degrre is added on the base extrusion, I think that the position of the round protrusion is changed since that is constrained to the top edge of the base extrusion.
Probably I am thinking having in maind how it works in I-deas but we have two other costumers that uses Peo-E aswell and they confirmed the same thing that "The only way to have draft for injection molded parts (there is not only one draft value) is to go after the extrusion/protrusion and add it". Again I do not work with Pro-e and probably I am missing somethig, but one thing I know for sure that all designs coming from Pro-E have missing drafts, all 100%. And this I think is only because the designers do not want to spent time with this "unimportant" feature for them.

RE: PROE vs Unigraphics vs Solidwoeks vs Catia
So you are saying that the designer is "BS"-ing me. do you think there is a easy way to ad different drafts in the same part and not spending to much time.
If this is true I will talk to his boss and show him that there is a fast and easy way to do that, because to tell you the truth it is very painful to add draft on an existing model, without calculating the mistakes that we can make not knowing what the parts does and how that is assemblied.
Thank you
RE: PROE vs Unigraphics vs Solidwoeks vs Catia
I have used SolidWorks,Catia and Unigraphics. in my opinion UG number one.
SolidWorks is very good (For Mechanical Design) but for surfaces design insufficient,if catia very expensive and heavy a program (For CAM a little bit bad )
But UG in every respect very good...

What kind of part can Pro/E do that UGNX2 can't?
RE: PROE vs Unigraphics vs Solidwoeks vs Catia
Drafting is a different ballgame. UG wins hands down.
"Wildfires are dangerous, hard to control, and economically catastrophic."
"Fixed in the next release" should replace "Product First" as the PTC slogan.

RE: PROE vs Unigraphics vs Solidwoeks vs Catia
GA62 is absolutelly correct and you are NOT. I can see, that you had never design an injection part in your life nor you ever design an injection mold. I fire designes who do not include draft. And I DO WORK in Wildfire 2.0 M060. There is no method in PRO-E to apply common draft to a part. If for instance I have 100 features in PRO-E, that need to be drafted, I need to make at least 100 draft features and this is assuming that I can use "intented design" method. If not then the situation gets really bad, since I will have to apply draft to individual surfaces. I know for a fact that PRO-E users were asking for extrusion whth a draft for at least 12 years to ne avail.
