I really miss the ability to trace an existing object in A360 in a new sketch. I find I'm going back to TurboCAD to create a DXF of what I want and then import it into A360.
TC has a great feature in that I can create a sketch by either entering coordinates of what I want for each point one by one or I can reference a point from the last point by line length and angle. This I guess is mainly for multi-sided objects but it is what 80% of my work consists of. See example attached.
I make jigs and often the CAD side is to document what I have actually made that works in practice.
PS I'm finally taking the 3D plunge after 15 years of 2.5D
