3 This document has been approved as the official reference for determining the graphical display, symbology, and electronic file management conventions to be used on all OUA projects. These Standards are designed to help OUA designers communicate requirements to clients, contractors, consultants, and others involved in project document preparation, project coordination, and construction. These Standards were developed using research from similar institutions, industry professionals, and the National CAD Standards . They are maintained with the full support of OUA management. Please note that these Standards will be periodically revised and updated to stay current with changing technology, University policies, and construction practices.

Michael Ross, Senior CAD Technician (513) 556-0909 AutoCAD/ Plan Room Manager David Galusha, CAD Technician (513) 556-1501 AutoCAD Support Ralph Jacob, Senior Staff Architect (513) 556-3162 AutoCAD Work Team Leader DRAWING FILE FORMAT The CAD software currently used at the University of Cincinnati is AutoCAD 2000 including Architectural Desktop (ADT R2). All projects prepared for the University must be submitted in a compatible .dwg format. If you experience difficulty accessing ADT R2, please contact the Senior CAD Technician (listed in the Introduction).

5 All projects developed for the University shall begin with the current standard prototype drawing file, submitted by the University Project Administrator. (Exceptions that allow the use of consultant-generated title blocks will be allowed only with the written permission of the University Project Administrator.) This electronic AutoCAD file is formatted to the layers, settings, and defaults specified in these Standards . If you require assistance with any of these files, please contact the Senior CAD Technician. CAD Standards June 2004 Design Guidelines AND Standards 5 Recent releases of University prototype AutoCAD drawing files include tabs for modelspace and paperspace.

6 The title block information is located on the paperspace tab. It is an absolute requirement that all graphic Design be produced at full scale in modelspace. Projects created otherwise will be returned for correction. External Reference Files Projects requiring cooperation among different disciplines must use a common base plan as an external reference file (xref). Such a file provides a single referenced plan that can be revised simultaneously for all disciplines. Changes and updates during Design are made to only one background plan (the base plan), which becomes the basis for updating all drawings.

7 This method, which is a requirement for all construction drawings at the University, will help ensure consistency throughout all disciplines. When creating external reference files: Begin all xref file names with XREF. Use BYLAYER. Purge before providing to other disciplines. Include all graphic elements. Include room numbers. Do not include dimensions, notes, or wall types. Insert at 0, 0. FILE NUMBERING CONVENTIONS All electronic CAD files must have a nine- or ten-character file number consisting of two parts. The first five or six characters ( xxxxx in Figure 1) make up the first part of the file number and represent the UC project number.

8 The Project Administrator will provide the consultant with the project number at the beginning of any project. The second part of the file number consists of four alphanumeric characters (D-nnn), representing the drawing number as it occurs in the completed drawing title block (see Appendix A, University Drawing Numbering System). This drawing number will include a letter (D) representing the drawing discipline followed by a dash and a three-digit (nnn) sequential drawing number. Figure 1 shows the file numbering convention; Figure 2 illustrates the file numbering convention for xref files. CAD Standards June 2004 Design Guidelines AND Standards 6 Figure 1.

This structure makes the list easier to use and accommodates future expansion. Layer names are alphanumeric and use easy-to-remember abbreviations. The layer disciplines shown below match the drawing discipline designations for electronic file identification. A Architectural M Mechanical C Civil P Plumbing E Electrical Q Equipment/Furnishings F Fire Protection S Structural G General T Telecommunications L Landscaping These layer disciplines will be followed by a select number of layer names from the full AIA Layer Guidelines .
