You can intersect a line with a plane to create a point at the intersection.
The image below shows a line and plane intersection creating a point, even though their depictions do not intersect. Remember that all geometry in SA are infinite.
There are a few things to keep in mind:
The line and plane need not physically intersect, since planes and lines are treated as infinite in size.
If the line lies in the plane, or the line is parallel to and not in the plane, no points will be created.
To Create a Point at the Intersection of a Line and Plane:
From the menu, select Construct> New Points>Intersection>Line and Plane Intersection.
Select the line, then the plane and the Construct New point dialog will 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 dropdown).
Click the OK button.
