I don't know of anything that works in the curve. When I was in the field I would use the plan in 1' interpolations to see where I should be at a certain point, but then you are wondering do you use MD as your reference point or Northing and Easting or VS so either way it can be a guessing game unless you have software to tell you. The formula for figuring it in the lateral will work in the curve, but always in reference to the LP so it will show you are high by whatever TVD difference is from where you are in relation to LP. Not good to tell a company man you're 562' high. lol Send me an email to twilsonj@hughes.net and I will send you some info.
