Converting 3d solid to mass element

[Anonymous]

Hello, 

I wanted to ask, why when I choose a bunch of 3d solids and convert them to mass, they are sort of combining together ? can I separate them?

thanks

Try this:
(This converts selected 3dsolids separately one by one)

(defun c:test ( / ss1 i1 e1)
    (if (setq ss1 (ssget) )
        (repeat (setq i1 (sslength ss1))
            (setq e1 (ssname ss1 (setq i1 (1- i1))) )
            (command "_MASSELEMENTCONVERT" e1 "" "_yes"  "" )
        );repeat
    );if
    (princ )
);defun
