You can create a point at the intersection of two lines . Or, if the lines do not intersect, a point will be created at their mutual perpendicular midpoint. (The mutual perpendicular midpoint is half- way between the closest points between the two lines). If the lines are parallel, no point will be created.
To create a point at the intersection of two lines, proceed as follows:
Select Construction > Intersection Two Lines Mutual Perpendicular Midpoint.
Select the first line, then the second. The Construct New Point dialog will then appear.
Leave the coordinates as-is (they are calculated for you), and specify the desired collection, group, and point name (or select an existing collection or group from the drop-down list).
Click the OK button.
