Hi welcome to the forum!
It’s great to see other users of OpenGrade!
That’s great, currently this was only discussed, as far as I know no one is working on it right now.
If you don’t mind, I would like to take a look at your source code.
Remember that there are 2 separate software discussed on this tread:
OpenGrade, like yours,
some upgrades from original:
com port for tool control
adjustable grading distance from survey line
adjustable view distance under and above ground with reference lines.
ability the reverse the survey line, to survey in either direction for tile plow.
ability to move the whole target line up and down.
ability to save multiple swaths for future reference.
Probably some other features I forgot!
and
OpenGrade3D, that works in a completely other manner, it can take survey of a whole field and with a third party software (like Optisurface) you design the map then back in OG3D you can grade the whole field.
