Merge nodes in autocad

[jordimoreno]

Please find attached the dwg with the example.

In this example I am trying to do edge surfaces (EDGESURF) from 4 curves in 3D.

In the example from the left, I can execute without problem the command EDGESURF.

In the example from the right the curves are not well connected in the upper right corner and the command EDGESURF does not work.

I would like to obtain some kind of command or lisp to connect automatically the two curves from the upper right corner.

The process would be, for example:

- Select the region affected

- Write a tolerance or fuzz distance.

And obtain as result that all the nodes within a distance between them smaller as the tolerance will merge in only one node.

Like this the curves in the example will be connected and I can proceed with EDGESURF.

Thanks in advance for your help.

Well actually you can never get those to join coz they are non-coplanar as you can see and im sure you yourself know coz you drew it

You could post in the autoLISP, CUI section for a request on your said lisp instead of here.

From what I can see a quick solution would be to go to its front view and use FLATTEN to get those lines coplanar with each other

Well, in fact I was using autocad to do the mesh of a finite element model in 3D, so flatten does not work here.

 

I am searching a command/LISP to superpose end of lines/3dpoly/splines when they are close.

 

Thanks anyway.
