Hey guys,
I have to model this attached chair, i remember seeing some plugin somewhere on net through which we can combine different objects to single one with smooth edge like bloob mesh at intersection. Or is it just my imagination and no such plugin exist 
Thanks!
Not sure if there is anything that will do a good job the way you describe it. You just want to connect the cylinders to the cone like thing? It could be easily achieved with poly modeling.
if you want to model that chair, first having the element right would be a good start.. the cone is smaller the arm is closer to the cilinder. so far it’s a simple union operation with fillet all around.
