You can project points along a working coordinate frame axis until it intersects with one or more surfaces. (If there is no intersection, no projected point will be created).
To Project Points Along the Working Coordinate Frame Axis:
When prompted, pick the surfaces to project to.
Select the points you’d like to project.
When the Select Axis dialog appears, choose the axis to project along.
The Point Naming dialog will appear. Enter or select the desired group to contain the projected points. In the Add Prefix or Add Suffix field, enter a prefix or suffix that you’d like to attach to the point names, then click OK.
