Patterns and Mirrors

[RedKnight26]

Motivation / Existing Problem
Currently (afaik), there's no way to mirror part of a sketch over a set line, or to take part of a sketch and make it a pattern like in Fusion360. This makes working on objects with multiple identical faces tedious and time consuming.

Description
When making a sketch, I'd like to draw a line and use a tool (similar to the existing vertical tool) to set said line as a mirror line which will reflect everything drawn on one side of it over to the other side.

Similarly, I'd like to be able to place a point, use a tool (similar to the existing midpoint tool) and select the point for my pattern to rotate around, followed by selecting my pattern and setting how many copies I want to make (evenly spaced apart).

Obviously these don't have to work exactly like this, but these tools feel almost essential imo.

If you need an example, both of these features already exist in Fusion 360
