It should be enough to  define a node with the UZ blocked at the point where the support is located.

Use the elastic (tab) support definition

I'm not sure if I understand this description correctly. Could you make a sketch of the model and indicate which d.o.fs you want to block, have elastic, release in particular nodes please?

the structure is a cantilever extention. from nodes 1 to node 3 is a continuous beam with a roller support at location node 2. i want to make it cantilever but i am struggling !

i also want to make node 3 and 4 semi rigid/fixed .

i have attached the poster for my structural project if this helps
