When you tell an object that it is to be a certain stitch type, the stitches will automatically generate. Also when you adjust or edit the object, the stitches will generate for you. But what if you want to do a complex series of edits on the object? It might be desirable to turn the automatic generation off for a while. You can do this with the ‘Delayed Generation’ button. As long as the button is pressed, and you are in ‘Create’ mode, your stitches will not generate.
