In a dumb part file features we want are either added or altered but still there are features remain dumb. How can such a part file be used in a real world environment?
I presume you mean dumb file , not dump file.
I create dumb files for the same reason I publish pdf's for drawings... they can not be changed by accident.
Also if you are sending the file to someone else, do you really want to send them all your hard work?
Thanks for indicating error.
By feature recognition a if a dumb file's feature manager design tree can be created what is purpose of hiding the hard work by means of dumb file?

Feature recognition will not have tolerance, equation or relation to other feature.
It won't know which dimension is important. Should I maintain holes center distance or distance to edge?
Dumb file load faster in assembly, usually.
Combine an assembly into a dumb part to help performance or make it really difficult to 'reverse engineer'.

Have you actually used FeatureWorks? Yes, it can help you create a parametric file from a dumb solid, but cannot capture the design intent. Often Usually, how a part is modeled reveals the design intent: what you are trying to achieve, the function/purpose of the part, method(s) of manufacture, etc.
Yes, FeatureWorks can help you achieve a parametric file, but I know very few people that have ever used it. Usually someone will recreate a new file by referencing the dumb solid, but their new file will have a logical modeling approach that FeatureWorks just cannot provide.
When making modifications to an existing injection mold for a complex molded part, particularly one with a long and sloppy FeatureTree, it may be wise to create a dumb solid model and edit that, instead of working parametrically, just to make sure you don't change any existing geometry by accident.
It seems a different idea. Thanks
I use FeaturWorks quite a bit because we have a Prototype Engineer who still uses Inventor and when it comes to production I convert everything I need to (or can) to SolidWorks files.
Many things don't convert as I would normally build the part.
Holes are just holes and loose features, in addition to all the things that others have mentioned in this thread.
I will often remove many of the features after running FeatureWorks and recreate them the way I need them.
I will often remove every detail and go down to solid bodies and rebuild - sometimes I just create a whole new part from scratch if it is easier.
Also, After running FeatureWorks on a Dumb Solid, you have to go into every sketch and define / constrain everything or change the origin and change the way it is made.
FeatureWorks does have advantages on more complex parts to see sizes, angles, and other geometry if you don't have a drawing with dimensions or details. You can open a feature sketch and dimension it to see what the dimensions actually are and then update the sketch to a better design intent.
I have also used FeatureWorks on just specific parts of imported models to correct poorly modeled geometry and/or make mating easier. There are a couple of valve manufacturers who have some pretty terrible 3D models, flanges are out of parallel with each other as well as the front/top/side planes, bolt circles not concentric, etc.
Hello Maha,.. (I kind of liked the dump file reference!... I'll add something below)..
I mean, you're dumping the intelligence for a dumb/static/stable data,.. is imho, like buying a finished part/component.
Also, imho... when you finish your design and it is released to manufacturing... the data should be locked/static/dumb.
Dumb is good!
^^^^That's the Correct Answer
Is there anything you don't have a model?
..the garbage inside the bin?
I bet you have more then enough to fill the bin.
Use a program that does direct edit. Iron CAD, Solid Edge, Fusion 360, maybe VX come to mind. They can manipulate solid 3d geometry much the way SW manipulates sketches. Select a face, move it, tilt it, remove it, replace it. Some of these can change values like radius values (edit imported fillets), or apply a dimension between faces and change the dimension. They can even control faces of 3D solids with relations like tangent, parallel, again, much the way SW handles sketches.
Here's a free ebook I wrote about the topic (big download). http://dezignstuff.com/STFTHBU/STFTHBU.zip

But it's not in a downloadable .zip file. - just allows you to read the post.
I am able to download.
Rick,.. yeah,..looks like forward is not working?... anyhow.. if you delete the the forum prefix in the url it works (image attached)
Just tried again and found if you click directly on the link in Matt's post it will give the Jive Error I show and no download, but if you copy the address and use it directly in your browser it does download.
Looks like a Jive issue.
Frederick Law ,.. you know,.. I can not argue with that at all... I've got so much $#@ on my drive!
We all do.
Therein lies the problem a lot of people have with what they consider dumb files. Yes I suppose you can consider them as dumb but a better way is they are a load of surfaces joined together that can be edited changed pretty well anyway you want.
FeatureWorks is next to useless on anything remotely complex.
Try to copy/paste the link. If Jive is saying it can't find it, that's the SW forum platform, so you're not getting to my site. I tested the link, so I know it's correct.
