how to join selection sets

[drafter007]

I have a list with multiple selection sets, i want to join them into a single selection set, ho?

Parse them with SSNAME, first item had index 0, and add to the first one using SSADD function. To get the size of a selection set use SSLENGTH.

[Tharwat]

maybe something like this would work ..... Try it ...

(setq s (ssget))

(setq ss (ssget))

(repeat (setq i (sslength s))
  (ssadd (ssname s (setq i (1- i))) ss)
)

You can use ACET functions for Selection sets :

(setq sss (acet-ss-union (list ss1 ss2 ss3 ... ssn)))

M.R.

Only with express tools... nobody has a function similar to acet-ss-union?

It is a mater of minutes to write one by yourself using the info above. If you got stuck, then post your attempt here for debug support.

What exactly do you have in mind drafter007? It appears that tharwats snippet will accomplish what you need.

[MSasu]

The Express function work with any number of selection sets, while Tharwat's example is limited to only two. I think that this is the reason of OP's complain. But said example code can be used effectively as a starting point to a dedicated function similar with the one from Express pack. This should be easy taking into consideration that OP had already some experience playing with selection sets.

That is correct , I meant to say exactly that

But i still want to see a function made by some guys with more experience ...please...
