disclose different devices aiding the user in marking out location and measurements for structural component fabrication. Layout tools incorporating, or providing means for attaching a measuring tape are disclosed, If measurements, other than progressive compilation is required, this becomes disadvantageous.
 
   BRIEF SUMMARY OF THE INVENTION 
   None of my searches have disclosed a hand held tool with means for the attachment of a mechanism for compiling progressive measurements, computing angular measurements and computing innumerable degrees, while using the same hand held tool as an aide of the delineation application of these results. Neither do they disclose a means for attaching cards with called for construction data. Presently, to keep a card with pertinent data at hands reach, and keep breezes from disturbing it, it is clipped to a clipboard, weighted down, or put in the users pocket, requiring multiple movements when progressing along the work piece detailing for fabrication. 
   My objective is, providing a one-handed held tool to aide the user in the marking and detailing of called for data, and performing calculations in a more productive manner throughout completion of the fabrication of a building. 
   My invention is a wrap around type device with flat, right angled, blades projecting outward from each other. One blade is an adjustable vertically oriented, slid able blade used in marking out component location on the narrow sides of multiple work pieces, or the wide side of a singular work piece, and is directed to a locking type measuring tape laying on the surface plane of the working place, contiguous to the work piece, said blade being guided, and adjusted in height, at the 90° turned-up end embodiment of a horizontally oriented blade, this blade used in marking out the adjacent work piece side with component placement location, size and description data. The turned-up end embodiment provides a calculator holding tray, with means for attaching indexed data cards to tray&#39;s face and backside. The placement of the measuring tape on the surface plane of the working place in a locked position, permits the user to progress along the work piece making markings at varying distances, or if necessary, retrace data, the user needs only the invention and marking instruments at hand to carry out the procedure.

   DETAILED DESCRIPTION OF THE INVENTION 
   Referencing my invention, it is used as an aide in the tracing out of perpendicular markings on a structural work piece necessary for the segmented placement and connection of components in the fabrication of a Buildings framework, the work piece described as a linear length of material, or linear lengths stacked, upon the surface plane of the working place, said working place described as saw horses, staging, a bench, or the buildings floor. Laying out and detailing for the fabrication of a building&#39;s wall assembly is referenced with drawings. The basic components of a wall, are the top and bottom plates, described as work pieces, plate to plate uprights called studs, cut up-rights called cripples, spacing to receive beams called beam pockets, backing for the connection of intersecting walls midway of wall length called channels, backing at the walls end for connecting to an adjacent wall is called corner, a lintel above an opening called a header, a lintel below an opening called sub sill, an up-right at a header end called king stud, and an up-right support at a header end called end cripple or trimmer. A wall with a raking top, the component description of top plate, or vertical components contiguous with said plate, the word rake precedes the description, i.e., rake plate, rake stud, rake cripple. 
   The most common material thickness in wood construction is a nominal thickness of 2 inches, sized to an actual dry dimension of 1½ inches, the second commonly used material is a nominal thickness of 4 inches, sized to 3½ inches dry. 
   Referenced in  FIG. 1 , the detailing tool with the interior face of the horizontal blade,  2 , facing down, loosening the knurled nut,  5 B, permits vertical adjustment of blade  1  from ⅜ inches to 6 inches, enabling making markings on sides of multiple plates. A flip-up tray,  4 , for holding a calculator, with means for attaching cards to the face and backside of said tray, with data from working drawings and specifications. Blades,  1  and  2  have paralleling straight edges,  1 A,  1 B,  1 C, and  1 D, sequentially aligned with  2 A,  2 B,  2 C, AND  2 D. The distance spacing of the straight edges, measure 1½ inches from  2 A to  2 B, 1½ inches from  2 C to  2 D and 3½ inches from  2 A to  2 D. The blades have ⅜ inch end stays,  1 F &amp;  2 F, end  1 F has engraved delineations at edges  1 B and  1 C, and at center locations between these straight edges. These edges and said delineations are aligned with dimensioned delineations of the measuring tape,  7 , for marking distances and component sizes. 
   Referenced in  FIG. 2 , the detailing tool atop the work piece,  6 , comprised of 2 plates stacked on the surface plane of the working place. At the start end of the work piece, markings are made tracing selected straight edges of the detailing tool, on the adjacent exposed surfaces, for the placement of the end component, and detailing descriptive data of the component on the top surface of the work piece. A measuring tape,  7 , is placed contiguously the length of the work piece, with the tapes end aligned with the start end of the work piece. The tool is moved to the next, nearest, component location with the selected edge of blade  1  directed to the measuring tape and positioned at the called for dimension distance, repeating the procedure of tracing out for the placement location and detailing called for data. Progression is made along the work piece in this manner, using the on-board mechanized calculator in compiling segmented measurements, performing calculations for angular measurements, and detailing data from the data card,  8 , to the opposite work piece end. 
   Referenced in  FIG. 3 , the detailing tool, with engraved delineations of blade  2  visually exposed, placed atop the work piece,  6 . a single rake plate. At the left work piece end, using the right portion of the tool, the pivot indicator,  10 D, and the rise,  10 C, calibration numeral  12 , is aligned with the outer edge of the work piece, an alignment guide,  9 , is tightly attached to edge  2 A contiguous with said work piece edge. Tracing along edge  2 D, and edge  1 D of the vertical blade, making a cut mark, this cut location becomes the start position of measuring tape,  7 , resting on the working place surface, pulled in a left to right direction. When the pull direction is from right to left guide  9  is attached to edge  2 D, the edges and engraved delineations of the left portion of the tool are used. Move the tool with the selected edge of blade  1  directed to the measuring tape and positioned at the called for dimensioned distance to the next, nearest, component location, repeat the procedure of tracing out for the placement location and detailing called for data. Proceed along the work piece in this manner, detailing called for data, and compiling the progressive segmented measurements, performing calculations for angular measurements with the on-board mechanized calculator.
