Honestly, the way PTC has completely dropped the ball when it comes to getting Pro/E into colleges is the main reason.  One of the reasons the SW users hers (who never actually really put forth any effort to LEARN Pro/E) are pushing for it is the lack of Engineers who can use Pro/E fresh from school.  I'd rather them hire experienced Engineers, but maybe that's just me....

So, I think it will look good on MY resume, so I'm going to put effort into learning it.  I will give it a fair evaluation after I've learned enough about it's capabilities, though I will say it will probably be very much like friends who are very experienced users in both and in general are saying.  We'll see.  There are some things I like about SW from what I saw already.  I'm curious about the GUI's all the i-phone kiddies seem to love......

And, from seeing their work, I'm sure I'll be more fluent in SW than they ever became in Pro/E.....and I'm also sure I'll even be better in SW than any of them.  Only one of them even remotely impresses me in SW.

So, my questions to those who use both is:

1.  What should I expect?

2.  What are the shortcuts/tricks?

3.  What is the easiest/best approach to learn it quickly and fluently?

4.  Using surfacing and the advanced features like I do, what are the comparable features and building methods in SW?

Anything else you think I might want to know.

Grazie!

Stay tuned dear friends!

1.  What should I expect?

You will be amazed just how similar they are.

You will also be amazed just how dissimilar they are.

2.  What are the shortcuts/tricks?

To each his own. Mine would not be yours. Find your path.

3.  What is the easiest/best approach to learn it quickly and fluently?

Start modeling, everything and anything....soup to nuts. Models, assemblies, drawings.

4.  Using surfacing and the advanced features like I do, what are the comparable features and building methods in SW?

Do not expect it to function like Creo. SW surfacing is not intended to function like you are used to in Creo.

Have fun....

You're gonna hate the quirks.

Everything else just takes getting use to.

Don't forget about mid-plane/between assembly constraints.

...patterning within sketches

Yep, that's all I can think of on the Pro side.

Steven,

Do you mean like the Style feature where you can "sketch" something and then drag it off the original sketch plane? OR the fact that the sketch can created/manipulated in a non-orthogonal (I.E. the sketch view is not perpendicular to the screen)?

Unless you have some super secret knowledge about SW 3D Sketch, they seem to operate pretty much the same.

Do tell! ;O)

3D sketch in SW is truly sketching in 3D by flipping the construction plane and generating relations in 3D space.

I wish I could say it was robust, but not really.  It is over-constrained in a heartbeat.

It fits into the nice thing to do to keep design intent consolidated in a single feature.

3D sketches are awesome for doing conceptual pipe routing. It is so much faster than trying to do sweep, to sweep, to sweep in Creo. Yes, Pro-Piping might be better, but we don't have it. I absolutely hate every time I get a project that has much pipe routing (which are seldom enough that we can't justify Pro-Piping) because that means I'm breaking out the sketch pad and spending a lot of time guessing and laying out pipe in sketches before I ever start modeling it in Creo. This wasn't an issue in SW.

Video Link : 6474

Steven,

Are you using Direct or Parametric? What Rev?

I quickly looked at the links you included  The first link had an example that the guy (Don?) was done by tagging through pre-existing point (I.E Old, Old school Piping method) in an assembly. Another example was using intersected curves then running a Sweep. But, unless I am still dense, I think that functionality being asked for exists in Style Curve. The 3D curve can be constrained anyway you like, just like a regular sketch, just without being restricted to a sketch plane.

Does the video still miss the point?

THAT is cool!  Looks WAY easier than the SW video.

I should have mentioned that Iwe're on creo elements/ pro 5.0, though I have and will load creo 3.  As for solidquirks, I have 2014.  so, before I can really do a direct comparison, I need to learn bpth creo 3 and SW.

I recently completed some SW training and as with most things there were some things I liked and some I didn't...

  • My main takeaway was I now understand why so many SW Users have trouble when trying to move to Pro/E (okay, okay Creo).  IMO SW seems to be much, much more forgiving when it comes to poor modelling practices (references in particular) than Creo.  The implications are no less problematic but it takes virtually no effort to "force" something where Creo might want you to resolve it.
  • The other thing was that the training I took instructed poor modelling practices... layer cake revolves in particular.  There seemed to be a focus on speed over stability.  What happened to the "old school" principles of a greater number of simpler features is preferable to a lesser number of complex features?
  • Datums/Reference Geometry.  I rely heavily on Datums, especially coordinate systems as opposed to geometry for constraining both features and components.  SW processes "mates" before assembly features, and Reference Geometry (Datums) are considered assembly features so it would take two passes to "constrain" a component by an assembly datum.
  • Geometric Tolerances appeared to be fully "dumb".  Where Creo limits you to valid specification of GeomTol you could apply anything in SW

Now what I did like were things that Creo seems to make more complicated than need be, or does not include an adequate "library" out of the box.  Things like materials, mass properties, appearances.  Overall the likes for SW were more immediate whereas the Creo benefits are much more subtle and many users may never encounter the need)

Training was done on SW 2015 which does seem to be much better than the 2004 version I previously used.  Like many of you, especially independent contractors I am also finding that Solidworks and Inventor have all but fully displaced Pro/E (Creo) in my local market which tends to be SMB's and start-ups.  Needing capability in SW and Inventor is just a reality.

Remember, it's not the strongest that survive it's those that are most able to adapt.

Bingo.  I'll go one further - Creo values careful modeling and deliberate reference selection, SW doesn't really care.  Creo has robust reference management tools (visible entity IDs, reroute tools, reference replacement tools, etc.), SW has almost none.  It's hard in SW to determine what feature an entity belongs to.

Furthermore, building carefully in SW is of limited value and seems to have little bearing on the robustness of the model.  In Creo, if I'm careful and take the time to tie features together appropriately, my models will be very robust and I can bend them to my will.  Doing the same in SW gives no such reward. 

With SW you can build very fast, using the most convenient reference rather and not worrying about the inevitable failures that will come.  When (not if, when) they do come, however, it's very easy to fix it when it breaks.  So, throw out what you've learned about robust techniques with Creo and just build and don't try to make it so it won't break.  I find that very hard to do.

It's hard for that not to sound condescending, but it's just the difference in how they work.  Creo rewards diligence, SW rewards speed.

Again, right on.  I've found that most SW users that persevere and learn how to master Creo end up preferring it.  I've converted many young, new grads who've grumbled and complained at first, but grow to love the level of control they get in Creo that SW can't touch.

The flip side is that I've seen good Creo users spend months using SW and come back with all kinds of sloppy techniques.

I've been playing with it all morning and that's kind of what I'm seeing.  where's the query-select?  How the h3ll do I know what reference is being used?  Got my first failure already on an absurdly simple part (all I can create at this point)......

Again, it's not really fair because I'm comparing creo elements/pro 5.0 to 2014, but for now that'll have to do.

Stay tuned!

If you know me personally you know i could talk for hours and hours on the subject.    The fact that SW is not a modular based package simply put's it into a mid range category.  Creo on the other hand has many modules to purchase.  For example Tesla.  They had a company wide meeting to ask all their new engineers what software they wanted and they all chose SW.  A year or two into the development of a vehicle they realized SW did not have the option for Vaulting (PDM) their files nor G2 or G3 continuity.... I could keep going.    The same sales person that sold them SW a few years earlier sold them Catia NOW because that tool has all those options they were looking for that they didn't know they needed when they made the first purchase...  And Catia like Creo is modular based.

When the baby  grows up they don't want to play with blocks they want more powerful toys that they did not know they need at the time of the original purchase.  That sales guy made twice as much money selling them twice playing up on their ignorance.  To me that guy is the problem here not Testla's mistake in the purchase.    Granted SW has come a long way each year.   Now, SW has 20 percent of the advanced assembly in SW that Creo has in a separate module we call 'Advanced Assembly'.  Can  you imaging not using Simplified reps to retrieve a 17,000 part Orbital Assembly?  That's the way it was before 2014 of Solidworks.    My favorite quote is when teaching Solidworks folks Creo and we do it a great deal.....   "I'm an expert in Solidworks and have been for 15 years'   My response is "dude.  if you were an expert at solidworks back when that packager rally sucked I can't believe any word that comes out of you mouth in the future"  Harsh but true.

Soooo, I got on the SW forum today and posted up about learning it from Pro/E, and asked for advice and comparative advanced features and.......crickets.  Wow.  Maybe they didn't like that I claimed to be a expert Pro/E user?

I also posted a bunch of the pics I have here in my photo album.

I also found a thread where people were posting pics of things they did.  While I saw some assemblies with many parts, or parts with many features (a lot less of those), what I really did NOT see, was parts or assemblies with complex SHAPES.  Nothing really sculpted or obviously "surfaced".  In 115 pages, what VERY little I found was of the "hack and slash and add rounds" variety, nothing truly surfaced.  I think THAT tells me a lot about what I needed to know about SW's (lack of) Industrial Design capabilities.

But, from what I've seen over the years, tried myself, and have read here and elsewhere, this is pretty much what I expected.

Your pretty close there, Frank.  The words PTC and Creo makes eyes glaze over at the SW forum.

This was my foray into the "where the heck is..."

Does Solidworks have an equation curve based on... | SOLIDWORKS Forums

Definitely more hacks on the SW side then on the more formal Creo "WorkAround^tm" crowd.

Keir, Doug & Dean make excellent points to be aware of. What I'll add are two things;

1) The options or configuration settings are not stored in a file like the config.pro, they are stored in your user registry. So, if you have need to work with different environments (i.e. using different option setting for different customers, etc) then you are going to have to look at the SW tool for exporting preferences and keeping various sldreg files to load prior to loading SW.

2) Be aware, some of the options that you can set might just scare you that they are available. There are setting that allow you not to fully constrain/define sketches and features. Go through all the settings, learn what they do, and make intelligent decisions as to how you want to have them set.

I found an interesting discussion in the SW forum:

https://forum.solidworks.com/thread/102012

Before I found the SW model, I modeled it in Pro/E and added rounds that I wanted to make the ends nicer (i.e. flat plane thru 3 points).  When I got the SW model, I exported a STEP into Pro/E and was pleasantly surprised at how good the "loft" was when doing a reflection analysis on it.  It almost perfectly matched the Pro/E model.  I think Pro/E has better boundary blend controls (tangent, control points, curvature continuous, etc.), and the round command has quite a few more options (SW does not have "sets" in the round command, or all the options on shape - variations of C2 round, etc.), or end transitions.  Anyways, it taught me a lot about how to work in SW, which was the main goal of me looking at the forum.  Here it is in Pro/E (of course).  Note I could have taken a feature or 2 out of it, but wanted to merge first because I thought it would give me a better overall surface.  I'll have to check that later.:

As an ID guy by training, your model and the SW model posted both don't quite capture the design in the photo.  In the photo, the edges of the legs appear to be a single concave arc or spline, both models appear to have more of an S curve shape to them.

I haven't looked at either file to see how or if that changes how it'd be made.

Fun shape nonetheless.

True, but I simply copied the dimensions and overall scheme from the SW model someone on the SW forum made, so I could compare apples-to-apples on the construction method and result.  Then I just had to add a tweak of my own (the additional tip rounds (because it looked cooler and always gives a 3-point plane).  Without having the actual dimensions of the table and the type of surface curvature, neither the SW guys or us could 100% reproduce it.  For instance, I can tell it's not 9" high, and .2 thick like the SW model. 

But yes, it was a fun little shape!
