@tig said: You can add Text labels to your SKP. You can then include Text in what is to be Exported as a DXF, under the Exporter's Options... Also ensure the DXF format chosen supports Text... Note how I deliberately mis-labeled two vertices as '5' ---oOo--- First thing TIG thanks for taking time and trouble to reply much appreciated, What I am trying to do is force SketchUp to change the internal numbering (not shown on the screen) of the vertices (points) before I export the 3D wireframe drawing For example if internally point 2 is X 0.0 Y 2.1 Z 1.3 I want to be able to export it as say 3 X 0.0 Y 2.1 Z 1.3 But want to change the 2 to 3 from the screen graphically. I am transferring geometry to structural computer models and want to avoid tedious re-numbering of the joints textually to rationalize them for design purposes. I did try tracing over the original model using a different layer in desired sequence and then deleting original layer which works but in practice is not a good solution. Maybe I am hoping for too much…………. Tony
