In AutoCAD VBA, if a certain curve or line and a horizontal coordinate x are known, how can the vertical coordinate corresponding to X be determined?

There are two methods: one is that you know the algorithm for this curve, which allows you to understand the relationship between X and Y, and thus determine the coordinates of Y based on X. Second, once the curve has been drawn, it is also possible to use the GETpoint command to directly obtain the coordinates of that point

getPoint must be triggered by a user click, right?

Is it a curve or a line? It’s probably difficult with curves; for straight lines, first determine the angle of the line and use tan to find the Y value

Just view the coordinates directly, isn’t that enough?
