At times we need to work on the same geometry for different purposes in different projects, and it would be handy if there is a way of exporting the geometry at our disposal.
Since PLAXIS 3D 2017 version, it is possible to export the geometry to DXF, STEP/STP, BRep and STL format using the command line: Export a PLAXIS model to CAD for post-processing.
Apart from the available command, there is a way to reuse the geometry through the functionality called Examine commands in the Expert menu.
