2 years ago I would like to be able to visualize the field in one specific plane only, currently I cannot find any way to do this.
Option 1: Use the Override Padding dialog!
- Click "Override …" in the "Padding" section of the Sampling Volume widget.
- Set an identical value for both the Z-minimum and the Z-maximum of the bounding box.
- Note that this solution only supports integer values, i.e. planes located on integer Z-values. However, if desired, you could always translate your wire loop in the Z-direction to achieve the desired distance.
Option 2: Use the Constraint Editor!
- Set the padding (bounding box) large enough to accomodate the "plane of interest".
- Click "Edit …" in the "Constraints" section in the Sampling Volume widget (or hit F3).
- Set Norm = "Z", Comparison = "Not In Range", Min. = 7 Max = 7, µ = 0, with the value 7 specifying the desired Z-plane.
- Note that this solution also supports floating point values.
Bonus-killer-feature: It would highlight with colors the points in this plane where the field vector is parallel to that plane [...]
I'm, not 100% sure, but it sounds to me that the already existing metric "Magnitude Z" would accomplish that? :) Like, it is parallel to the Z-plane when the magnitude in the Z-direction vanishes.
EDIT: I have fixed another bug related to Python 3.10's more strict type checking. Please pull the repo again!

I would like to be able to visualize the field in one specific plane only, currently I cannot find any way to do this.
Example:
I have a complicated wire loop located flat on the XY plane. A real world example would be for example the boundary wire of a robot lawn mower.
Now I want to visualize what the sensor in the mower is actually seeing, the sensor is always located in a plane of maybe 7 centimeters above the wire loop (or even more if the wire is buried below the surface).
For simulating this I would want to design the wire loop in plane XY and then I would need some way to specify another arbitrary plane (in my case the plane 7cm above the ground) and plot the field only in this plane.
Bonus-killer-feature: It would highlight with colors the points in this plane where the field vector is parallel to that plane because this would be where the mower would think the wire is located. Maybe some kind of heat map where the color depends on the Z-component of the vector (or any other parameter of the field to make it more universal) and then be able to export this 2d heat map as an image. This would be extremely useful.
