extract vertices coordinate

Hi,

I am a newbie to autocad 3D and really need help. I need to extract the mesh vertices coordinates, anyone knows how to do that? either using the built in commands or lisp code.

when working with 2D model, I can use point to get the coodinates of the nodes but in 3D, it is difficult to put a point in each of the vertex of the mesh

thanks a lot for the attention

Can`t you us the "id" command then select point . I just tried it on a mesh corbal and it gave me x y z coordinates

A way could be to point the vertices one by one -no need to insert points. To proced, set the osnap properly and enter in the command line MULTIPLEID

Click the vertices one by one. Press to finish, press F2 to bring up the text screen, select and copy the relevant part. Paste it in Notepad, edit the text (CTRL+H=find and replace) and you get a list of the vertices.

As a beginer in AutoCAD, are you familiar with Lisps?

thanks folks for the reply,

actually i am working on the boundary element method computation and thinking to use autocad to create and meshing the models. the models coordinate will be then computed using fortran so actually i am dealing with many points or nodes which make it impossible to point them one by one. i am still not familiar with lisp code but wish to study about it. any suggestion to proceed on my problem?

thx for multiple hint didnt now that
