I am using SolidWorks and I can tell you that I much prefer Creo when it comes to inserting, placing, and mating.
SW may have midplane, but Creo has the ability to place AND mate parts in 5 clicks, 4 if rotational freedom is allowed.

Re: Repost of an old issue...only now it's a real problem.
It doesn't just require style.
I've had parts "corrupt" themselves with similar regeneration issues that could not be found by layman's means.
I would suggest, if it is an option, to submit a support case and submit the files.
If nothing else, you might learn, and share, how to go about tracking down these illusive assignments.

Re: I'm a beginner using Creo Parametric 3.0 Academic
Interesting workaround. The palette corresponds to a particular folder, so you should be able to save your sections directly to that folder as depicted here: How to save user defined sketch in palette of Creo parametric? - GrabCAD
Here's how it works in the non-academic versions: Using saved sections/drawings in sketcher Of course the exact locations will vary depending on which version of Creo is in use.

Error Message calling for geometric data
From Beginner Tom using Academic version.
When I go from Sketch to Extrude I often get this error message when I hit the OK green check.
"Incomplete Section" - reason - "Section must contain geometric entities for this feature"
Where did all the entities go? Figure is blue. What does blue color means?

Re: Error Message calling for geometric data
Tom, your sketch does not for a single closed area and that is why Creo will not accept it for an extrude feature. While working on you're sketch, it should shade the interior of the closed area in yellow. If it does not, you will not be able to extrude with it. In your example, you have two small horizontal lines outside your oval. If you remove them you should be okay.
There is is a set feature validation tools near the end of the Sketcher toolbar to check for closed area, overlapping entities and others. Use them to make sure you're sketch is what you expect it to be.

Re: Error Message calling for geometric data
Here we go again. How do I recover geometric entities when I get this blue color? Have I lost forever the data? This is after I hit the OK button on Sketch, tried Extrude and got a 2D sketch, then went back to Sketch and got this error message.
↧
Re: Error Message calling for geometric data
Although the sketch is extruded it is a surface. The only way to extrude an open sketch as a solid is to select the thicken icon in the extrude dashboard. The orange color is a preview of what the geometry will look like and the dark blue identifies the geometry as surface geometry. As far as the error message are you creating the geometry as cunstruction geometry? There is an icon that can be selected that toggles whether the entities created are construction geometry (phantom lines) or sketch geometry (solid lines) which I don't see in your image. If you exit a sketch that just has construction geometry I don't believe you can get that geometry back. I'll try to upload some images if you don't find the options.

Re: I'm a beginner using Creo Parametric 3.0 Academic
I will dig into your suggestions. We call ourselves the Zheshart (Zheshart, Republic of Komi, Russia) English LEGO Academy. We can't really use the term Academy officially because it triggers a number of zoning issues. Maybe next year. My wife teaches English to Russian Grade 1-11 students. I don't speak Russian very well yet, but with her help I hope to teach "software for the 21st Century." This includes Creo Parametric, Mathcad (I've been working with it since Mathcad 3), Microsoft Office - especially Word, Excel and PowerPoint, R for programming and Sibelius for music. This software is now so sophisticated I think it will take years for students to learn even the most basic software capabilities. (We've reached the singularity. Computers are smater than we are) We will also teach how to access Internet sites such as Wikipedia, YouTube, Google Earth, Perseus, Gutenberg and commercial sites Amazon Kindle and Amazon Audiobooks.
We definitely want to get involved with LEGO robotics although I wonder how useful the LEGO robot control language will be in the real world. I'm aware of YouTube videos on how to 3D print LEGO pieces. Please send links to LEGO STL libraries if you have some. I'm aware of libraries and images of Lego dimensions, but I have not found a LEGO library of STL files. Media Library - About Us LEGO.com I was delighted to discover that Creo's How to model almost anything uses LEGO examples you can build without a 3D printer.
We are also interested in object scanning techniques to create STL files which can be further manipulated or expanded by Creo. I've found STL export software in Creo Academic. We don't have a 3D printer, but that's at the top of our list, Supposedly there are workable printers for about $200. We can live with small size models, but we want precision. Creo 4.0 supposedly will address 3D printing in a big way.
I'm obviously experiencing a second childhood at age 75.

Re: Relations: within sketch or feature assigned (?)
Model relations are certainly more discoverable by the average user.
If the dimension record for the sketch and the feature is the same one, then they just failed to create a check for interference. I'm guessing they aren't the same record or they use two different links to the same record, which is why the software isn't capable of noticing without a much larger effort.
Mostly I use sketcher relations to force shape into place; especially when a lot of relations are required so that it doesn't overwhelm the feature/model relations that are to drive function (such as centering, or making margins equal)

Re: I'm a beginner using Creo Parametric 3.0 Academic
What you are doing is wonderful, Thomas.
I too enjoy playing with Legos at nearly 60 y/o. The programming language for Mindstorms is National Instruments. I would say that today, this is a very applicable teaching tool for young minds and geezers like us. If I was still a young person, I would much prefer the Lego programming learning over boring old CAD learning.
You do not need, or want STL ready Lego files. you can always generate one from solid files like Step, Parasolid, or Neutral formats. This way you can tweak the part before printing. Often times, small adjustments are necessary for particular printers specially since it has to mate with existing bricks.
I am really curious if a 5th grader can grasp Creo Parametric. How large a part of the curriculum is dedicated to CAD at this level?
Do not overlook packages like Rhino 3D (Rhinoceros) where some kids excel beyond belief. This too would have interested me way beyond what CAD can do.
Not having an artistic bone in my body, however, could make that a short-lived experience. This is more of an organic modeler which also help 3D printers shine.
And building a 3D printer as part of the class will also be of serious learning consequence. You can tie 3D printer protocols with Lego programming. Making a Frenken-printer today is almost 2nd nature to a lot of people. I suspect in Russia, you will find very enthusiastic young people to help out where more tech level expertise is required.
Jakub... you are the Lego Master here. Can you help out linking Thomas to some Lego libraries?

Re: Relations: within sketch or feature assigned (?)
Model relations are easy to find but that screen gets messy fast.
Right now I only have 4 relations at the model level driving the design elements requires.
I started editing feature relations and found that to be very cumbersome.
Then I started adding them to the sketch itself and learned the sketch takes precedence.
So of course, had to go back an remove the feature relations.
In past designs I've ended up having to regenerate twice to have everything catch up.
Often times, Creo doesn't want to regenerate the second time because it thinks it is done.
Yet, you know there is a feature that will change if it does regenerate as it should.
That is part of what prompted me to ask the question.
I do know about Initial and Post Regeneration option in Relations but that is only active at part levels relations.
What I haven't found is the logic of when things require 2 regenerations.
And does that have anything to do with this query?

Re: Relations: within sketch or feature assigned (?)
Multiple regens required is a sign of a circular reference; that is, that some output along the way affects some earlier stage. Unlike ordinary circular references, Creo does not report a certain class of them as an error. I think it only indirectly discovers them because at the end of regen some item is flagged as changed after dependencies based on it were made.
Why Creo fails to regen when it should has been a mystery to me; I've written before that I think it is speed optimizations that skip a few cases they should not. Excel has the same sort of issues, but has much easier dependency trees to deal with. Even then, Microsoft gives up their optimizations beyond a certain size.

Re: I'm a beginner using Creo Parametric 3.0 Academic
Glad to hear LEGO's programming language has a future. I've outlived DOS, RPN, WordPerfect and numerous operating systems. I think 5 graders can handle Creo. That's certainly what PTC thinks. We'll start with 2D. Maybe after the first year I will figure out how to fix my 3D model:
With Community suggestions I discovered freebie GrabCAD GrabCAD - CAD library . They have a bunch of LEGO files, but I haven't found any made with Creo. I'll look into CAD file conversion. Creo 4.0 may address this problem???
I hope 5th graders can handle Creo. I plan to make it and a 3D printer a big part of the program. We'll see. My present challenge is to learn the program myself. Rather than printing standard LEGO parts which can be bought we will focus on Creo design enhancements of LEGO parts.
I find Creo amazing. For instance how would you find the volume of this? In the bath tub by water displacement?
Excel is also in a league by itself. 1st graders can learn numbers with it + - * / ^. 11th graders (in Russia there is no 12th) can run Pivots and optimization algorithms or play with 10^6 X 10^6 matrices using downloaded Big Data. MIT uses Excel in its Supply Chain Logistics courses Supply Chain Fundamentals | edX To get an idea of where MIT is going look at Additive Manufacturing Course . $5000 for five days!

Re: fosi compatibility across Editor version 5 to 7
Hi, sounds interesting. Did you use Styler in 7.0 to create a style (.sty) file and then also a screen FOSI? If so the FOSI should work in 5.4 through 7.0. Prior to 5.4 I know there were conversion issues. I do not use Styler to update our FOSI's just and ASCII editor and have the same FOSI running in 5.4, 6.0, 6.1 and 7.0.
More information would be helpful, let me know.
