We can learn from each other - or not

I use SolidWorks, and notice many models for download here that are represented as SolidWorks models, (and which can, indeed, by opened in SolidWorks) are removed by a generation from their original files by which they were created, so their design tree and operations used to create their geometry are no longer present. Indeed, it's not even clear, in some cases, that they were actually produced in SolidWorks.
I, for one, have always appreciated seeing how others do things- I'm of course aware that my way is not always necessarily the ONLY way. Is there any good reason to upload a model without it's creation visible?

It could be done as a way to prevent others from claiming work as their own.
I have seen a few times on the site that uploaders will hand out the STL or STEP files for free, and then in the description they will state that other file formats are available if you ask.

I do agree with what you are saying though, and there are a great deal of lessons that could be taught in that manner.

There is no requirement to upload native files. Each user will do as they wish.
I think it is best when native files are available, as it is possible to see how it was built, learn something new, and it makes it a lot easier to modify the file.

If you find a model that is not available as a native file, send the uploader a message. Many people are not willing to upload their models to the site, but may be willing to share with a single interested person.

Creating models for various clients we would never send native files out - until payment was verified. In many instances only 2D PDFs got sent for approvals then payment then models got sent... Sad but true. And even at that some clients where not running the same software so STEP and IGES was all they could get to run. They kept the natives just for any future work that may need to be done and the ability to go to whomever with it.

Also, a good reason for a universal format here, I'm running SW2016. Some are posting work in 17 and up versions. I can't open them.

So as much as I'd live to see how someone created a model, if I just need the geometry to get a job done, I'm not all that concerned in which file format its in as long as its correct, accurate, watertight and I can open it.

There are native files that I would not provide here. Especially because when one gives free, people tend not to respect the work done to underestimate the time invested. A bit like the files that are downloaded and that people do not even bother to "like" them ... it's a lack of respect. I like it when someone asks for the native version by personal message. It promotes cultural exchanges.

Thanks to all who have thoughtfully responded to my initial question! I understand the situation that my initial nativity blocked me from seeing. Like everywhere else, dishonesty exists, sadly, among designers and engineers (and why wouldn’t it? It’s just part of the human condition). The main reason I put this question out here was that, while I have relatively small models that I have uploaded here in the past, I have one that took quite a bit of work on my part, that I can upload in its native SW 2015 format (so people can see what a pain in the butt it was to create) and I shouldn’t worry because actually, it’s not really worth anything on a commercial level- it’s purely art, and it’s not even my own art- it’s Maurits Escher’s – his “Relativity” crazy house- that has gravity pulling in all orthogonal directions. I’ve seen other solid models of this house, and some look quite accurate, but I’ve never seen any as comprehensive and complete as the model and assembly that I made. Maybe nobody even cares- it was just something I’d always thought would be cool to realize as a solid 3D model, because with it, one can look at Escher’s creation from any angle they wish. It will be uploaded soon, and everyone can then see what a nut-job I really am.

This site is heavy on SWorks usership, so I'm a bit surprised that more native files aren't uploaded. I tend to agree, that you can learn a lot from reconstructing a 'well built' model via the build tree. I've learned a lot doing that myself.

I'm sure everyone has their own reasons for not sharing native files. Me personally, I'm a Siemens NX user. This forum seems rather light on the NX user-base so I just don't bother, assuming most are using another system and will want to import a universal format anyways.

I learned a long time ago that you don't share your 'unique' design ideas on the web. Got burned on that years ago when I simply queried a message board for potential product interest. My query was deleted, because I was "not a sponsor" and lo and behold, some months later, a couple of the sponsors were offering a carbon copy of my original design. Live and learn...

If I were a SWorks user, I'd be more than willing to share but I'm about 6 versions behind so I tend to talk 'modeling' in general terms.

If I had to make a suggestion... it would be to offer up your own models for critique. I've noticed that folks love to model things for one another here... and I'm sure you'd get some feedback that way, especially with something a bit more 'challenging'.

Best of luck.

You can ask the designer for original design purpose of education. I got some 3d model this way.
