What's the best way to create realtime updating sections like Orca has

Hi
Back when I was designing boats I used to use Orca but nowdays I design model ships , I do really need the updating sections that Orca provided but simply can’t justify the price of Orca for this functionality alone for a hobby
I am talking about sections that result from the contour command or from object intersections, either would work as long as they update constantly, like every tick.
I realise it might bean expensive process but it needs to be automatic so you can monitor it while editing control points.
relying on history is too sketchy and tends to break.
I am assuming something can be hooked up in Grasshopper?.
I just really need to know how to fire the contour command constantly or everytime a point is moved.
I would very much appreciate some help on how this is done.
Thanks

There’s at least two things that are difficult about this:

  1. You would need to have updates while you’re changing control points of a surface, that is typically not available in Grasshopper. Some scripting or coding may help here.
  2. It will be hard to get this to be performant enough to see real-time updates, let’s say with more than 10 frames per second.

Hmm… I have not really played with Grasshopper but that surprises me that Grasshopper has no ability to keep firing a command.
I have tried the project curves with history but it does not work for me, as soon as the command is executed the record history goes off (not in bold) and when you edit the surface points the curves do not update. hence why I said its flaky with this tool, lofting is fine and things like that.
