I resume this discussion to thank stefano garbin. I realized, rereading, that I broke him but broken the boxes!
Thank you so much again!!!

Here I take advantage of it to resume the speech interrupted because of the exams and personal events.
as suggested by stefano I should adopt the following strategy:
1-select all rivets (esel,s,ename,,beam4)
2-for each rivet (with a *do cycle) select the ends knots
3-then select the hardpoints attached to those knots
4-recording x,y,z coordinates of hardpoints couple
5-if the rivet should be aligned to the z axis check if the x,y coordinate pairs are the same
6-if so I do not go to change x,y so that they are the same
7-end cycle *do, regenerated mesh and relaunch solution
I thought about the following code:
finish
/prep7
esel,s,type,,4 (select all beam elements4 ie my rivets that are 2377)
*I,i,1,2377
nsle,s,all (the knots attached to the selected elements)
(At this point I should select hardpoints attached to these knots)
What command should I use?
Does the classic ksel know it doesn't work? ?
Thank you all.

I think I'm wrong in selecting the nmodes maybe. . .

the command is a little different:ksln,r or the reverse nslk
after you have selected nodes attached to beam elements.
a tip: ansys has a help not indifferent. I don't add anything else

Thank you very much.
then I solved so:
finish
/prep7
esel,s,mat,,5,select the material of rivets
eplot
esel,s,elem,,277895,277926,1 (this is the range of elements to be selected) !select the elements in a certain range
!
nsle, all! I open the knots attached to the elements
!
ksln,s,all!prendo i keypoints attacked to nodes
/gtype,all,node,0!do not plot the knots
/gtype,all,elem,1!do not plot the elements
/gtype,all,keyp,1!plottare keypoints
/gtype,all,line,0!do not plot lines
/gtype,all,area,0!plottare areas
/gtype,all,volu,0!do not plot the volumes
gplot!comand to plot multiple entities

eye that the second line "elimina", that is, makes useless, the first.
esel,s... select items from the whole set of elements!
esel,r... select items as a subset of a previously selected group.

You're right.
rereading I noticed the "gaffe".
I did the thing graphically, I hope I can move on.
Thank you.

I finally removed the wrong hardpoints and replaced the correct ones.
the problem now is to go to meshare the various parts.
in fact if I use the "mesh-tool" of ansys I get the following error:
"fail to mesh area (number area) which contains hard points".
Is there any strategy that allows me to go to realize the mesh without the appearance of this error? ?
in some cases it creates mesh but at the hard points the knot is not created.
I'm crazy.

see if you make mesh with the mode: mshape,1,2d
It works .. as it is right when you have hardpoints...
You won't pretend to meshare the model on maps... do you?

I had no claim to make it on maps.
I believe that the mshape,2d command is also good, if necessary, to map it if you can or free; Maybe so something good comes out.
Thank you very much for the reliability.
How does the panel model look? :
ps: to solve the problem mesh they advised me to pass, for the mesh, to ansys wb.
Do you think it's okay? ? ?
pps: I try to import the wb file and see if I can combine something then.

My idea was just to solve the mesh problem.
on the famous ansys forum I exposed my problem and a user suggested that, maybe, it was more convenient to go into the wb environment to solve the problem of mesh generation with hard point.
in apdl when I go to meshare with the command you suggested to me (I first used mshape,0 (ele. quadrangolari)
mshkey,2) the following warning appears and I do not know whether to worry or not sincerely.
[Chuckles] [Bleep] [Chuckles] [Bleep] [Chuckles] [Bleep] [Bleep] [Chuckles] [Bleep] [Chuckles] [Bleep] [Bleep] [Bleep] [Chuckles] [Bleep] [Bleep] [Bleep] [Bleep] [297 Time= 12:01:37]
shape testing revealed that 81 of the 2383 new or modified elements
violate shape warning limits. to review test results, please see the
output file or issue the check command.
"
I also tried to create the iges file eventually to do a wb analysis (for mesh purposes) but I just can't create it.
I'm freaking out empty.

dear eih64 in fact I do not want to change road but every time I make a mesh come out 125320 warning!! !
I'm demoralizing! ! ! !
about warnings mentioned above "shape testing revealed that 81 of the 2383 new or modified elements

output file or issue the check command. "Is it better to go ahead or try to solve the problem from now on? ? ?
the creation of rivets will be realized by means of text files with a command of the type:
finish !esco from the environment in which I was first
/prep7 !entro in the preprocessing environment
*do,i,1,160! start cycle do with counter "i" from 1 to 160 (*)
ksel,s,,7699+i!select the keypont number 7699+i
ksel,a,,8699+i! also the keypont number 8699+i
nslk!select the knots attached to these keypoints
*get,n1,node,n,nxth!memorizzo in n1 the number of keypoints greater
*get,n2,node,n,nxtl!memorizzo in n2 the number of keypont minor
type,4!setto as current element type 4
e,n1,n2!creo an element between n1 and n2
*end
!(*) I carry out 160 times the sequence of operations between *do and *enddo varying "i"
I hope you don't give problems like my previous colleague.
Thanks milel again!
ps: the .zip file is encrypted! !

the problem on the rivet is a problem that does not exist.
as, once the mesh of the areas the hds convey the presence of a knot and therefore you just have to put a beam 4 ...
the macro as well as structured can be cause of problems ...
but it doesn't matter now, bets to the mesh of the areas....
the error that is reported can say everything or nothing.
Just change the control parameters of ansys is the error disappears.
even the simple change of the size of the element can result in the elimination of the "warnings" you see ...
if this is the model of your previous colleague ....(student) of warning he had also ... but it is all related to the modeling that was adopted ..
do not want + see warning because this rattrista .: shpp,off,,nowarn
Come on.

Thank you very much for your availability.
I start meshare a section at a time and see what we can pull out.
thanks again for the availability.
I will definitely update you!
ps: even if I do not see the warnings there will be the same, so... better leave them!!
pps I don't remember badly for some section you have to create mesh to congruent knots, these I will leave them for the last in order to devote more time! !
