Dear Foum,

I am wondering how you add accessories in your electrical schematics or if you simply ignore such accessories.

I have the following situation / scenario:

I am creating my schematics, selecting the proper components and I am happy with it the pure electrical schematics are perfectly under control.

In real world - or the 2D cabinet layout, I need much more components then registered in SWE bill of materials.

For instance:

Lets say I place 10x din-rail mounted relays.

By expirience we know those relays are not nicely fixed on the din-rail.

The solution is easy:

Add some "end brackets" such as Phoenix Contact 3022276. This part will nicely fix the relays to the din-rail.

I am happy.

What is good practice to add these end brackets to the BOM?

Currently I am trying following and making up my mind, all solutions are not optimal:

a) I am adding the missing "end brackets" by expirience to the real and modified bom (EXCEL)

b) I am placing the 2D components in the 2D-Cabinet layout (in this step, I see where "end brackets" are missing)
    I am  adding an accessories to the component, in the example above, the very left and very right relay will have an accessory, the "end bracket".

    The end brackets are nicely shown in the SWE BOM, life is good but a lot work.

    Further to the "lot of work" (at some point they have to be placed anways) I see trouble to use the part of the schematics again in other projects.

c) Add end brackets directly to the 2D Layout, which is creating a new component mark.
    Creating a new mark is not a good idea for me.

What is the best approach in order to place these accessories into the bom?
