CAD Standards - Massachusetts
CAD StandardsRevision 2: February 2013NOTE ON REVISION 2: FEBRUARY 2013The DCAMM CAD Standards have been revised – Revision 2: February 2013 – to updatethe manual to Autodesk AutoCAD 2011 format and to reflect the name change of DCAM toDivision of Capital Asset Management and Maintenance (DCAMM).
DCAMM CAD STANDARDSFOREWORDEach year, the Division of Capital Asset Management and Maintenance (DCAMM) managesseveral hundred million dollars worth of projects. These include architectural andengineering activities, construction management, maintenance, surveys, studies and needsanalyses, and other projects in keeping with the mission of DCAMM“ to serve the citizens of the Commonwealth by providing professional andcomprehensive services to state agencies in the fields of public-building design,construction, maintenance and real estate.”Data for these projects are collected in graphic and tabular form, most typically usingComputer Aided Design and Drafting (CAD) technologies. Complementary technologicaltools; Geographic Information Systems (GIS) software, total stations for surveys, and database technologies, are also used in data generation and collection. These data are utilizedimmediately in project related activities, e.g. planning, design, and construction of statefacilities, and are also used for a variety of post construction activities, includingmaintenance, space management, renovations, and management analyses, to name but a few.Post construction, the data are used to support diverse activities of state agencies to whichproject data are delivered.Recognizing the need for consistency and data compatibility among a variety of datadevelopers, project applications and post construction activities, in early 2007 a CADStandards Committee was formed within DCAMM. The committee was charged withdeveloping a set of CAD standards that would reflect DCAMM data management needs, andthat would be compatible as far as possible with National CAD Standards. DCAMMstandards would be complementary to the “DCAMM Standard Specifications”, the DCAMM“Designers Procedures Manual”, the DCAMM “Cost Estimating Manual” and any and allother DCAMM documents and regulations promulgated by DCAMM. The DCAMM CADstandards Manual is not a specification of what software products are to be utilized inDCAMM projects, but rather a specification of how graphic and tabular data are to bedelivered to DCAMM. The DCAMM CAD Standards have been developed with a view tocompatibility with and complementarities to emerging technologies, specifically BuildingInformation Model (BIM) software.Early on, the committee determined that an essential method of ensuring data consistencyand compatibility among the various data providers would be for DCAMM to develop aCAD “seed file”. This file, a digital version of DCAMM’s CAD standards, would beprovided to DCAMM consultants for use in DCAMM projects. The file would automaticallyset up the consultants’ computers according to the standard, thus insuring all consultants’ filedeliveries would be consistent and compatible, irrespective of the source and or discipline.DCAMMRevision 2: February 20132Foreword
DCAMM CAD STANDARDSFor a detailed description of the Seed file and Titleblock provided please refer to Sections 4.0through 4.4.The CAD Standards Committee was comprised of representatives from the followingDCAMM offices Facilities Maintenance and ManagementLeasingPlanning, Design and ConstructionReal Estate ManagementAdditionally, comments were solicited from DCAMM staff with particular expertise infunctional and/or application areas, e.g. surveying, project management systems (PMAS) andCourts, and client agencies currently using CAD. Input was also solicited fromrepresentatives of the local architectural/engineering/construction (A/E/C) community. As faras possible, all points of view have been considered in developing the DCAMM CADStandards.To assist in the preparation of the standards and the seed file, DCAMM retained the servicesof Microdesk, Inc., of Waltham, Massachusetts. Microdesk was selected based on its priorconsultancy experience in similar projects, and its capabilities as an application softwareprovider for the full gamut of disciplines utilized in DCAMM projects.It is recognized that the disciplines associated with DCAMM activities are constantlychanging. Periodically, this manual and associated seed files will be revised to reflect suchchanges. It is the goal of DCAMM to maintain a set of CAD Standards that are timely,current, and which reflect the state of the art in technology, data management, and currentmanagerial techniques in design, construction and post construction activities.DCAMMRevision 2: February 20133Foreword

DCAMM CAD STANDARDSPURPOSEThe DCAMM CAD Standards Manual establishes requirements and procedures for thepreparation and submission of CAD based drawings throughout the project life cycle.Adherence to this standard insures that both DCAMM internal staff and consultantsinvolved will receive and produce graphic and tabular data in a consistent format. Thisconsistency will improve the compatibility of these drawings internally and the efficientexchange of data between DCAMM consultants, and client agencies.The DCAMM CAD Standards Manual largely reflects the National CAD Standards, Version 3.1.In the case of differences between the two documents, the DCAMM CAD Standards is to beconsidered definitive for DCAMM projects.The role of an individual assigned to the project determines the level of understandingrequired of the CAD Standards. For CAD operators, designers, and supervisors athorough knowledge of CAD related elements associated with a project is crucial. Theproject manager however only requires a general knowledge of the CAD Standards andthe means by which they are employed to create a project. Both levels of knowledge willbe possible through the use of this manual.The CAD system adopted by DCAMM is Autodesk AutoCAD 2011 format. Alldeliverables must be compatible with this format. Throughout this manual terminologyand references will be made that are unique to this Autodesk application.This manual is intended to be used in conjunction with The Designers Procedures Manualeffective June 2005.ABOUT THIS DOCUMENTThe chapters within this manual describe how DCAMM uses CAD and how to configureAutoCAD to support DCAMM’s CAD Standard, which it has adopted.The appendices, which follow, support the chapters in several ways. In addition,appendices have been provided to support CAD related subject matter.DCAMMRevision 2: February 20138Purpose
DCAMM CAD STANDARDS1.0ACCESSING THE CAD STANDARDSThe DCAMM CAD Standards consists of a series of support files, which are available at theDCAMM website located at anagementcad-standards.html.The “DCAMM Standards” folder contains the DCAMM Seed file, DCAMM Title block, DCAMMCover Sheet and a pdf version of the DCAMM CAD Standard Manual.1.1USING THE STANDARDS FILESThe Standards directory contains two primary types of files: files that do not require ongoinguser interaction to utilize and files that do require ongoing user interaction to utilize. The firsttype refers to files used as AutoCAD support files, which only need to be copied once to theproper support folders. The second type refers to files such as Borders and Title Sheets alongwith their associated revision blocks. These files do require some user interaction to utilize ina drawing.DCAMMRevision 2: February 20139Accessing The CAD Standards

CAD models based on partial point clouds. CAD models will be represented as polygonal meshes. Hence, we will use term CAD mesh model to refer to faceted CAD models. Our system is designed to match point clouds, acquired by a single 3D scan, to complete CAD mesh models. This is accomplished through a segmentation procedure and local matching.
