Reading docs about Step-by-step in Flux to route PCB traces: start routing from a pad, continue, change angle with a key, switch layers and auto-drop a via, finish/cancel routing. Include how to route across multiple layers..
Gathering PCB design instructions.
Reading docs about How to add a Keep Out rule in Flux to prevent copper pours/traces in a corridor; object-specific and selector-based Keep Out; entering the distance value..
Searching for keep-out rules.

Crafting the final answer.
Below are the exact step‑by‑step instructions from the Flux documentation you can follow to finish routing, pours, and the isolation keep‑outs.
Routing traces (start/finish, change angle, cancel)
This is the most relevant entry I found related to the topic.
“To connect parts, hover over a part to reveal its terminals, then click on the white dots to begin routing mode. You don't need any tools. simply click where on the white dot to start wiring. To complete the connection, click on the terminal of the other element.
Connecting parts
While in wiring mode, you can also change the wire angle (elbow) direction of the route by pressing the “f” key. To cancel the routing mode, press the escape key.”

Create and edit copper polygons (pours)
This is the most relevant entry I found related to the topic.
“Creating a Polygon
To create a polygon in Flux:
Hover over a pad in your PCB design
Right-click to open the context menu
Navigate to Start Routing Polygon
Click on the canvas to place points for your polygon
Shift while placing points to enable free-angle mode (otherwise points snap to 45° angles)
Right-click to remove the last point
To complete the polygon, either:
Click on the middle of the pad you started from, or
Double-click anywhere else on the canvas
Editing Polygons
Once you've created a polygon, you can edit its shape:
Select the polygon in your design
Double-click on the polygon to enter edit mode
In edit mode, you can:
Click and drag existing points to move them
Double-click on a point to delete it
Hover near an edge to reveal midpoints that can be clicked to add new points
Click on the "Finish Editing" toolbar”

Add Keep Out rules (for the isolation corridor and pour clearance)
This is the most relevant entry I found related to the topic.
“Example 1: Creating a Keep Out rule between a specific pad and all other objects.
- Option 1: add an object-specific rule to the target pad and write the Keep Out distance. Typing 1.5mm in the keep out rule will create a 1.5mm distancing.
- Option 2: create a new selector-based rule and use the selector to match the target pad. You can use the pad designator to match it by typing #[designator] in the selector textbox. Then typing 1.5mm in the Keep Out rule will create 1.5mm distancing.
Example 2: One of the most common use cases for this rule is to set the distance between a net and copper fill or a polygon. Keep-out rules can now be applied directly to nets, making it easier to manage clearances.”

Make multi‑layer copper cutouts for the corridor
This is the most relevant entry I found related to the topic.
“Keep Out Rule
In the case where you’d like to create a copper cutout around a pre-existing element simply add a Keep Out rule. This will push the auto-generated copper planes away from the part at the distance specified. The keep out rule will only be applied to the layer where the object exists. To create multi-layer cutouts, you'll need to use a zone.
- Select the object to create a copper fill around (such as an SMA connector or a mounting hole.)
- Navigate to the layout rules on the right and add a keep out rule.
- Add the keep out size. Remember you can select different x and y keep outs by typing 10mm 5mm
- Flux should automatically regenerate the copper fill, thus creating a copper cut-out around the component” Source
Optional: learn routing across layers
This is the most relevant entry I found related to the topic.
“Flux supports multi-layer designs. In this tutorial, we'll cover:
Configuring the board stack-up
Moving objects between layers
Routing across multiple layers”
