How can I make inclined support in SAP2000?

Inclined support can be made in SAP by rotating the local axis of joints as follows: Select support joint From Assign menu select: joint _ local axis if your structure -for example- in X-Z plan, then rotate the local axis about Y by the required angle

Inclined Supports Steel E =29000 ksi, Poissons Ratio = 0.3 All members are 10 feet long.
To Do Determine support reactions.
Determine X-direction displacements at joints A and B.
