Willy Tschager Wrote:* So I might keep open several models at the time and they show all up in my All Models pin but how do I copy a submodel from one .mpd to the other?Drag&drop. Make the destination model current, open "All models" section in the Part bin and drag&drop the desired submodel to the main edit window aka destination model. This works for sure.
Similar trick may be used for export of one ldr from mpd: create new model and move the desired submodel there (press "C" to move it to 0,0,0). Then you have a model with exactly one submodel containing all parts. Then, select it and choose "move to the current level" and save. Unless there are any missing pieces like the information about steps and other invisible source lines, it should work.
