Point Finder Results NOTE : The tool searches for a point on an edge that is parallel to the Y-Axis, moving through the region of interest in a negative-to-positive direction relative to the X-Axis. Best results are generally obtained by when the guideline is placed on, or very close to, the point to be found. Use Search and Edge Detection parameters (Advanced Parameters) to further configure and refine the finding of the correct point entity.
