Feature Recognition for Sheet metal

Ability to change the k-factor for the radius for a part from step format.

Possibility to add an allowance to the radius. The part remains the same. It only adapts to the flat pattern. This is not a k-factor. Add allowance (magnification size)

@dusan.naus.trz  Do you have the original .ipt file for this model?

[dusan.naus.trz]

Hi,

@sgwilliams 

Why ipt model? Everything is shown in this video https://www.youtube.com/watch?v=VjIkDy27uIE

[sgwilliams]

@dusan.naus.trz  If you have the .ipt why would you need to change the .stp file? Just change the .ipt file and then generate a new .stp by exporting the file to .stp format. It's a rather simple process.

On the other hand if your bringing in a 3rd party .stp file that was generated with a different CAD system then I think you are going to be very disappointed. If Creo has done it it is probably because they have the backend access to be able to do this as it is most likely somewhat native to this software. I doubt that Autodesk does or ever will have. 

Some interesting information, this is a quote from ISO 10303-21 Wiki, the standard for .STEP-File. It states:

Possibly the only advantage of STEP files is that they are widely adopted in many CAD software. On the other hand, its format, and specially the EXPRESS has a few disadvantages:

• the format is proprietary, specification is not freely available (you have to pay for it)
• it is not possible to sequentially read a STEP file (because entities can be in any order and they can reference other entities forwards and backwards), therefore the entire file has to be read into memory and tokenized before parsing.

This tells me that there is a lot lost in the translation and I doubt that you would be able to edit the model features as they are coded so that you cannot on purpose. The mapping entities are set in such a way as that you cannot change them. This format is used for maintaining its original geometry so others cannot change it. What your asking for is not what this standard was originally designed for. It will give you the basic solid but no individual features to work with.

You do not understand. Why don't you read the careful comments above?

Feature Recognition in Inventor only Part

Please for everyone. Before you start writing comments. See all the links in the idea.

Context

When a customer receives a step file from a vendor, then the customer only adds a Custome size in Creo. In Inventor, you must recreate the part.
When a worker arrives who burns and bends a sheet metal. The worker will say add me to Flat Pattern Custom Size, then the bend will be good.

[sgwilliams]

It's obvious you got nothing from my advice in the last post. I did go through all your request. They are not realistic as I explained. Good luck!

feature recognition for sheet metal is very helpfully. I agree about that.

FeatureWorks functionality since 2012 in Solidworks = Wake up Autodesk EN https://www.youtube.com/watch?v=AvVFkR-p7Wc CZ https://www.youtube.com/watch?v=odCgFj_zIms

I mostly work with sheetmetal and sometimes I'm in the need of changing thickness on an imported part, i.e. going from 1.5 mm to 1.2 mm thickness.

If the part is simple I usually redo it from scratch with the desired thickness, if it's complex I usually leave the original thickness and change the k-factor to get the corresponding flat pattern extension.

It would be nice to have a "Change thickness" command to do this automatically, should have options to keep inner or outer (or even median) profile, and set bend radius.

I want Solidworks 🙂 Time 19:22. I would need to sweep the middle of the trajectory.
