Do you know, is there any trick or option, to select multiple contacts of macroelements and to change their contact type simultaneously (at one time), using ATENA 3D Engineering ? I have a numerical model, a structural wall with shear connectors, which has more than 50 macro elements, summing more than 650 contacts and I have to change their properties using other 3D Interfaces..

Thank you so much !
