Detailed explanation to step 6:
the easiest way to remove the superfluous surface parts after the opening extrusion is the following
6.1. remove the surface at the hole bottom (created during the extrusion, coinciding with the opposite macroelement surface)
6.2. create an opening in the macroelement surface, using the lines remaining in the plane after the extrusion (which previously formed the superfluous surface deleted in step 6.1).
Finished.

Hello ssaber,
in pt.6, check how many what surfaces there are at the side where the opening ends. Delete all of them except the righ one which should stay there, i.e., the one covering the whole surface except for the opening (the area between the outer edges and the opening edges). If you can not find it, delete all of them and create the right one manually from the edges. It may be easier/more comfortable to create 2 surfaces instead of one, each covering half of the area between one of the shorter boundary edges and the opening.

hello
I also have  this problem
it is giving me an error message as following :

(x)    The surface n.3 and the surface n.7 are intersecting each other!
(x)    The surface n.3 and the surface n.8 are intersecting each other!
(x)    The surface n.3 and the surface n.9 are intersecting each other!
(x)    The surface n.3 and the surface n.10 are intersecting each other!
(x)    The surface n.3 and the surface n.11 are intersecting each other!

please explain with an example or put one file of Atena including an example.
tanks a lot.

Dear Dr. Singh,

when creating an opening in a macroelement in ATENA 3D program the process is the following:

(1) Create the macroelement without the opening

(2) Define the joints for the opening. Typically they will lie in one of the surfaces
     of the original macroelement

(3) Connect the openning joints to form lines

(4) Define an opening

(5) Extrude the opening by a certain length such that it exactly ends
     on the opposite macroelement surface

(6) After the extrusion manually delete the surface that remains
     at the bottom of the opening.

(7) Now the opening should be ready

In case you still experience problems, please contact me directly at cervenka (at) cervenka  (dot) cz.

With best regards

Sir,
I am trying to provide Headed reinforcement in the column joint. To do this, I am trying to create an opening in the beam, so after that I can fill it with steel plate to which I can attach the reinforcement bar.
I am trying to create an opening in the macroelement as described in Atena 3D User Manual
3.8.2.2.2 (e) and it is giving me an error message as following

(x)    More than two surfaces are connected to the edge n.43!
(x)    More than two surfaces are connected to the edge n.44!
(x)    More than two surfaces are connected to the edge n.45!
(x)    More than two surfaces are connected to the edge n.46!
(x)    The surfaces do not form a closed boundary of the macroelement!

Please advice on the above problem.
