Auto-Locate - Point On Wall

The Auto Layout Point on Wall mode is only available for the following equipment:

This advanced layout mode allows you to compute the position of a point on a wall using only the non prism EDM mode. The routine will interpolate and determine the location of the wall and will compute the theoretical perpendicular offset from the design point to the plane defining the wall. The laser pointer on your instrument will point to the location that you should mark.

MEP Module

This advanced feature is available when the MEP module is enabled.

Procedure

Define Wall

When you start the routine you will see the Auto-Locate Point on Wall dialog.

On this dialog you can specify the point you want to locate on the wall, plus define the plane that defines the wall.

The first option allows you to point your instrument at the existing wall and lets the software determine the existing location of the wall by taking some shots automatically to determine the plane.

The second option lets you define the wall by using an existing line in your project or by defining the wall by two points.

Target Heights

When using the auto-locate routines you will not need to use a vertical offset. The routine will always default the vertical offset to "No Vertical Offset" and enable "Use Auto-Location".

Important Notes

It's important to understand the importance of finding the plane that defines the wall. In the following image you will see that a design point is to be located and marked on the wall. During construction, walls are never perfect and will differ from the design location. Since the laser pointer is being used to locate this point, if all the instrument did was turn to and point at the theoretical position you will see that it would mark a spot clearly in the wrong location.

Layout will prevent this from happening by determining where the wall is by taking several shots to derive a plane. The point is then intersected with this plane and the instrument will then turn to and point directly at the intersection point.

Once the location is marked you can then store it and locate your next point.
