Hi Jon, it´s agine me :)

first at all thanks a lot to your help last time, but i found another way to solve my problem ( i had use  deformation and then repare the lost connection betwen the lines whit one Toll in VB which i wrote (not so elegant but works)) but that´s not what i´m into now.

we (me and my civil enginieer) found this picture in net and wething we could use the system for our structure, we had try it in a model and it works

the question are the forces, if the structure is symmetric it´s no problem there, but if we try to make it littelby asymmetrical are the forces not everywhere the same, it´s possible to use some of your tools to check the forces or deformations ( "problem" is the force translation schould not work an all directions )  see te pic

every beam works as lever, do you see some possibility to make structural analysis for this ? somtrhing what show as which deformation( idea is to change the position of the upper points=the support lines (lenght, angle etc) change too) of the structure is possible?

thanks a lot to all your help

cheers Mike
