For me, the biggest missing features pattern features. Creating a circular pattern by copying features and having to calculate the angle for each instance takes a long time. I’d rather select the features, select an axis or point to rotate around, and then number of instances. And more pro would be able to then set the start and end degrees if I wanted to just pattern, say a half circle. And have this available for sketches or 3D.
Then the next feature would be able to pattern along a spline, being able to set the quantity along the spline (e.g. 5 instances along the spline), or the distance between instances on the spline. Final option for this feature would be to orient with the spline or not.
