Ok - understood. For simple entities like a line or a circle the "Line tool" / "Parallel with distance" would do the job.
For more complex objects I would recommend to get familiar with the use of Polylines. You can create a shape in first place as a Polyline or you can create a Polyline based on a Selection. The nice thing about a Polyline shape is - you can use the Polyline Offset Tool to handle easily the needed offset to compensate the kerf of a CO2 Laser etc. etc. etc.
Check this out (yes I know - it's ugly!):
Try this for yourself:
Load this drawing and play around with the Polyline / Offset tool (Menu -> Draw -> Polyline -> Offset). An additional Option-bar will pop up and you can put in the correct value for the kerf.
Will this suits your needs?
