Dan Pihlaja May 8, 2017 8:39 AM (in response to Sachin Murigesh)Here is another way of doing something very similar. It is a hybrid of solids and surfaces. Maybe it will work for you as well.

Re: Why can't 3 surfaces sharing a common edge be knitted together ?
Sachin Murigesh May 8, 2017 10:45 AM (in response to Dan Pihlaja)thanks Dan for showing another method. I can already see where this can come handy.
Similar to Euler's Formula which relates number of faces, vertices and edges for any nonintersecting polyhedron is there any formula that governs surfaces. Is it the because of this criteria we cannot create 3 surfaces sharing a common edge? Just curious to know.

Dan Pihlaja May 8, 2017 3:04 PM (in response to Sachin Murigesh)Not sure....but according to some of the things that I have read, 3 surfaces sharing a common edge violates this formula:

EDit: Sorry, I forgot to add it....I meant to include some bits copied from that website:
Here it is:
The EulerPoincaré formula describes the relationship of the number of vertices, the number of edges and the number of faces of a manifold. It has been generalized to include potholes and holes that penetrate the solid. To state the EulerPoincaré formula, we need the following definitions:
 V: the number of vertices
 E: the number of edges
 F: the number of faces
 G: the number of holes that penetrate the solid, usually referred to as genus in topology
 S: the number of shells. A shell is an internal void of a solid. A shell is bounded by a 2manifold surface, which can have its own genus value. Note that the solid itself is counted as a shell. Therefore, the value for S is at least 1.
 L: the number of loops, all outer and inner loops of faces are counted.
Then, the EulerPoincaré formula is the following:
V  E + F  (L  F)  2(S  G) = 0

Christian Chu May 8, 2017 11:18 AM (in response to Sachin Murigesh)Can you ask yourself a question: does it make sense to you if these 3 surfaces are knitted together to create one? What you expected the result after knitting these surfaces ?
