Especially in projects with many 3dbs or with connection points used again and again, certain sketches are multiply used, where copying is very time consuming. Much more simple and time saving is copying of sketches via batch run.
With the function Edit tables in batch run, option Insert sketch, a selected sketch is added in all projects and there in all 3dbs.
The new sketch is added to the 3D history [3D History] with a consecutive number.
Open the context menu command Automation -> Edit project in batch run [Edit project in batch mode] via the same project (to copy to all 3dbs there), another project or a directory.
Select the Insert sketch option in the top list field.
Select sketch: Click on the button and enter the path to the sketch file.
Layer name [Plane name]: Enter the layer name on which the sketch is to be inserted.
If layer does not exist [If plane does not exist]: Select either the Do not insert sketch [Do not add sketch] option or a specific layer.
