Dear ETABS Community,

In ETABS, how can I get the coordinates of joints tagged with parentheses?

For example, because of the meshing in shell slabs, some joints need to be created internally by ETABS in order to produce the sub-shells. I was wondering whether we can get the coordinates of those internal joints...

This is an example of internal joints created automatically by ETABS:

Hi,

Check this article on CSI Wiki:

https://wiki.csiberkeley.com/display/kb/Internal+joint

"Joint coordinates and information may be displayed in tabular format through Analysis Results > Element Output > Objects and Elements > Table: Objects and Elements - Joints. Internal joints will have a blank entry under Joint Object."

Dear avscorreia,

Thank you very much for reply. This is a table in which you can get the global coordinates of the internal joints. However, how can I know which is which. As an example, how can I get the global coordinates of the joint tagged with "(1785)"?

Thank you!

Unfortunately You can't!
