Attribute with names starting IDS (generator note?)

[Maxim-CADman77]

There is an Inventor add-in named Attribute Helper.

On some 3Dmodels it lists several attributes with "InternalName" starting with "IDS" (IDS_AXIAL, IDS_START etc.):

I'd like to know what does this starting mean and if it has any relation to the functionality of component generator (the 3Dmodel is a compression spring).

...or maybe "FDesign" (name of an Attribute-containing folder) hints Inventor that this stuff was created with a generator?

The attributes(with IDS) look like from the DACC(Design Accelerator) addin, you can double check this if you create spring from DACC. Usually you need not to edit the data(properties, attributes etc.) added by other addins, if you are working on your own addin you should just handle your own data. Change or delete the attribute added by other addins(like Frame Generator, DACC etc.) may cause problem for them.
