Hi guys, first and foremost, I apologise for not replying till now. Work's been extremely busy the past two weeks and I've had little free time at my disposal.
Here's what I'm trying to do (please look at picture below). I want to create a construction plane parallel to face 'A' and passing through point B.

In this particular case, I could use Plane Along Path and set the distance to 1.00, which moves the plane all the way to the end of the path, which happens to be point B. Of course, this workaround works only because the path happens to be perpendicular to face A. Assuming B was just a point in space, the only solution I can think of is to measure the distance using the Measure tool, and then use the measurement as the offset, but that's a bit too convoluted. Another rather messy workaround would be to extrude a temporary construction body using the "to object" parameter, then create the construction plane on the face of that body, and finally delete the body.
The same problem exists when using the Offset Faces tool, there's no option to offset to existing object (sorry, indeed, I meant TO object, not from).
Conversely, the Extrude tool allows extruding from and to existing features, and the Tangent Plane uses an existing plane as reference.
I hope that makes sense 🙂
