## Abstract

A collaboration tool is presented for accurately guiding two or more communicating users to reference common locations in similar but separate architectural drawings. The collaboration tool includes a transparent planar sheet having at least one squared corner, and a grid of squares imposed on at least one side of the transparent sheet. The grid of squares has an X axis and a Y axis originating from the at least one square corner. Each square in the grid of squares is associated with a unique X-axis designator and a unique Y-axis designator. The apparatus further includes an aperture provided within each square of the grid of squares, for allowing a marking instrument therethrough for making a mark at a designated location on an architectural drawing underneath the transparent planar sheet.

## Claims

### Claim 1

An apparatus comprising:
a transparent planar sheet;
a grid of squares imposed on at least one side of the transparent sheet, the grid Of squares having an X axis and a Y axis, each square in the grid of squares being associated with a unique X-axis designator and a unique Y-axis designator; and
an aperture provided within each square of the grid of squares.

### Claim 2 (depends on 1)

The apparatus in accordance with claim 1, further comprising a template section provided in transparent sheet adjacent to the grid of squares, the template section having a plurality of traceable shapes.

### Claim 3 (depends on 2)

The apparatus in accordance with claim 2, further comprising a ruler imposed on the transparent sheet adjacent to the grid of squares for providing a linear scale.

### Claim 4 (depends on 1)

The apparatus in accordance with claim 1, further comprising at least one first line perpendicular to the X-axis and at least one second line perpendicular to the Y-axis, the intersection of the first line and the second line defining a focal point.

### Claim 5 (depends on 2)

The apparatus in accordance with claim 2, wherein the traceable shapes include landscape elements.

### Claim 6 (depends on 1)

The apparatus in accordance with claim 1, wherein the transparent planar sheet is made of vinyl.
