Hi Agileba,
If i understand you correctly you are asking if it is possible to obtain a list of element types from diffecrent profiles (like standard UML, BPMN 2.0, ArcGIS, etc) that you can use on a diagram. The answer is: no, there is no easy way to obtain these.
In practice though this should not really be a problem since mixing of (elements in) profiles is in general not a good idea: profiles are intended for modelling specific problem domains or according to specific standards. A well-constructed profile will offer only those elements that should be used on a specific diagram, through a toolbox or through a popupmenu (quicklinker), or both, and often prevents you from drawing 'illegal' relations in diagrams.
Even if you're using EA primarily as a drawing tool i'ts better to stick to a limited numer of profiles, like the standard sparx basic, views, and extended UML profiles. There is always the option of altering the shape of elements through custom stereotypes with custom 'shape scripts' or using an alternate image for an element.
best regards,
Paulus
