Deform flat straight into a curved one 1

[PrintScaffold]

Greetings all!

What is the best way to model a part that exist as a straight piece but is getting deformed along an arc in assembly? My problem is that I haven't found the way to deform the same body that models the undeformed state. The solution I've came up with is to use one body swept along the straight line for the original undeformed state (for the drawing/general documentation purposes) and use another one swept along the arc with variable radius for the deformed state. Haven't found the way to make the same body go along either straight or curved path. Am I missing something?

Sorry, I've messed up the title. Not sure if I can edit it. It should read 'Deform straight part into a curved one'.

Did you try with Deformable Part? I have attahced two movies, that shows how to define deformable part and how to use it in the assembly.

Hi, SvenBom!

Sure I know about the deformable parts. In fact I was referring exactly to the deformable part usage scenarious. I probably was a big vague about this, sorry for that. The parts I have in mind are not stock-like as in your example, but general machined parts which nevertheless need to be deformed in the assembly. There are real-life scenarios which require exactly that.

It would help if you would poat an image of the part, or better yet, the part file itself.

Yes, sure. Here is the file. It is greatly simplified and dimensions are arbitrary, but the situation is real-life. This parts are straight, but in assembly they are bent along the radius.

Yes, but your example is not so much different to mine.
I have slightly changed your model. Instead of extrude, I have used Swept command and then defined everything again with deformable part. Then I have drawn an arc first in the assembly. The deformable part was then positioned according to this arc.
I would use this method, if the part is deformed differently in every assembly.
But, if the part is deformed the same in every assembly, I guess you could also use reference sets. Just create both bodies in one file and then place undeformed part on Model ref set for example and deformed part on new Deform res set for example. Then, when you are placing your model in any assembly, just use the Deform ref set.

OK, the best approach, or at least the simplest, is to go the Deformable Component route. In this case create your straight model using a Sweep and then when you define the Deformable Part, leave out the Datum CSYS and the path. Then inside the assembly simply create a Datum CSYS where you want the part to be located and add a curve/sketch defining the desired curved path.

To see how this would work, download the ZIP file which contains a new part and a sample Assembly. Juat add the part as a Component to the Assembly (you can place it anywhere you wish) and when NX asks you to provide the missing objects select the Datum CSYS and then the arc and hit OK.
