Is there flexible part option in assembly?

I have a shaft for which i want to vary my diameter in the assembly without affecting the part.

Is it possible in Inventor?

Its there in ProE. Its called "Flexible".

[#2]

I think you are looking for "adaptive" in Inventor.

[#3]

Flexible is used for sub-assemblies within assemblies. Having a cylinder assembly that you want to stroke within assembly.

An adaptive part changes with repect to geometry referenced by another part within the assembly. If the shaft diameter is adaptive (projected geometry from a bore-hole), when the bore hole changes the diameter of the shaft will change.

If you want parts to change by tables, you might look at iParts.

@ above...

I dont want to use iparts. What i want is, as soon as i place a shaft in assembly mode it should ask for the diameter of the shaft in a dialog box. I should be allowed to change the diameter of the shaft without affecting the part.

For example: when we place a bolt from content center, it asks for the diameter in a seperate dialog box.

Is it possible?

If yes, then please upload the file.

In Inventor this makes no sense.  The part is the shaft.  Even with your example of a bolt from the Content Library, you make the selection, then the part gets created to that dimension.

If it is specifically a shaft that you want, you might look at the Design Accelerator for shafts.  Or, you can create your own Content Library shaft that will allow you to choose dimension(s) before placement.  But you can't change a component of an assembly without changing the model, because that's all the component is.

What you are asking about, is an iPart.

@ above...

I am well aware about iparts.... but what i am asking is something else....

shaft was just an example.... what i want is as soon as i place a part it should ask for some specified dimensions of the part... when i give those inputs the part should be placed... but the orginal ipt should not change its dimensions... 

its called flexible part dimension in ProE assembly.... i thinks its not possible in inventor....

coming to iparts... i have to create multiple parts in the ipt (which means if i want my diameter to vary between 50-100, then i have to insert 50 rows which in turn creates 50 ipt files).

If we have flexible part option to vary the part dimensions in assembly (like for content center) it would be easier and file size will be reduced.

If you know how to create such parts like conent center parts, please upload the file. it would be very useful for me.

You can certainly create your own Content Library parts.  You want to place as Custom, which allows specifying a dimension or dimensions rather than picking them from a table.  I don't have any instructional materials, and I haven't done such a thing for a year or two, so someone else will have to jump in here.  If you search in the Help and in this forum, I think you should search on Publish to Content Center (or Library), and also Part Authoring.

Create a new assembly and try placing the attached ipart.

Browse to save new file.

Set your dims.

Does this do what you want?

Those 50 parts are still derived from a single base part.  Any changes you make to the base part will be reflected in all of its derived iParts.

Also, Content Center parts are iParts.  Each time you place a component from the content center or change its size, Inventor checks to see if the iPart with the specified dimensions has already been created, and if not, it creates a new iPart file.
