You can save loads of time if you often create very similar drawings of your parts and assemblies. First, you need to decide which types of Parts and Assembly drawings that you would like to manage. You might have one or two types of Detail Drawings. Maybe you have one or two types of Master Assembly drawings and then different Sub Assembly drawings like Welding and Mounting drawings. You will need to decide how you want those types of drawings to look like. Then create templates which reflects those types of drawings. Each Part and Assembly can then be connected to its own template and later be "mass-exported" from the 3D-scene.
