    Smile Vector Help Needed

    Hi

    I have a plane with the equation

    21814x + (-20063y) + 698z = -1941121897

    I have a point located at xyz coordinates 1003811,998176,100803.
    How do i calculate the xyz coordinates of a point located in a direction normal to the plane above, at a distance of 100 units from the point above?

    Appreciate any help you can provide.

    The vector was determined from 3 points in xyz space which were located around the circumference of a cylinder (pipe).

    The coordinates 1003811,998176,100803 are located near the centre of the pipe, however i wish to determine the xyz position located 100 units from this point orthogonal to the plane given.

    Thanks
