Perhaps BooleanUnion is what you’re looking for?
Maybe you want to group them?—-Mark
I tried to do that as well, yet in the next step I need to Merge all Coplanar Faces and when I group them it does not work
why dont you just post your file instead of letting everyone guess any solutions?
yeah I can do that sorry

your surfaces have shifted a bit,
after you fixed that you can use PlanarUnion, but as you can see some surfaces dont actually touch the rest. or in some areas not enough to merge. if you want the entire pattern to be connected you would have to expand the boarders more or rethink your pattern slightly.
To Join two surfaces in Rhino each surface must have at least one edge which is adjacent to an edge of the other surface. “Adjacent” means the two edges are within twice the absolute tolerance setting of the file (1) for at least a short distance, not only a point or several discreet points. If there are only larger gaps or larger overlaps between the surfaces they will not join.
Two surfaces which contact only at a point or a set of discreet points will not join.
JoinEdge can be used to force surfaces larger gaps or overlaps to join, but JoinEdge can cause problems with further operations on the surfaces or export.
(1) Absolute tolerance of a file can be set in Options > Document properties > Units. In general the absolute tolerance should be smaller than the smallest detail and any manufacturing accuracy requirements. It also should generally be set when a project is started and not changed.
