My favourite is his quote from Cecil Spencer, which was written in 1956 and supplied by ReMark: This question as raised some great debate on CAD tutor forums. Rule #3: Add call outs to improve clarity. This usually means the correct use of GD&T, proper finish call outs etc… Rule #2: The drawing should not have any ambiguity that leads to making too expensive of a part. Rule #1: The drawing should convey enough information to create the correct part without asking any questions.

No set is perfect and a professional office providing the service should help manage a client’s expectations of this itemĪ client deadline should never be missed: do what it takes to meet it and ensure it’s a complete and accurate setĬharles Bliss left this neat and succinct list on MCADforums: Here’s a thought provoking response from Dean Saadallah on the Autodesk forums:

Of course there are exceptions like Civil will have grid north and Arch, Struct, MEP would have Plan North. All disciplines’ drawings should match if possible, at least have the same building orientation.Don’t over-dimesion! Dimension in one location like the plans, and reference them on details and sections, easier to change once instead of chasing them all.Keep within time/budget if possible, if the scope outweighs the budget bring it up to the PM before you go over budget.Only enough detail for the purpose of scope and/or deliverables (ie: concept, 35% review, issued for bid, etc.).Drawings need to be created to good drafting standards, lineweights, clarity, accuracy, to a given Cad Standard.Thoroughness, Readability and Accuracy, in that order.Īnd these in the AUGI CAD Manager’s forums: Here is a great response from Doug Barense On G+ You can read my summary of the answers at the end of the post. Here are a few that really caught my eye.

I asked the same question in the AUGI, Autodesk, CADtutor and MCAD Forums and I had some fantastic responses. Is accuracy important? Or is it a given that all drawings should be correct? Should drawings be done to a standard? Is it more important that your drawing are done on time, or within the budgeted hours? Does the CAD part of the job matter? If the information you need to communicate is on the page – that’s good enough right? What makes a good technical drawing a great technical drawing? I’m interested in hearing your views. We all have our own opinion – often based on our industry and our companies needs. The multidisciplinary approach of this text and its supporting materials are intended to broaden the appeal of the curriculum and increase student interest and, it is hoped, future enrollments.This is a question that comes up frequently. We include architectural drawing because our experience has shown that many (if not most) first-semester drafting students are interested in careers in the architectural design field, and that a traditional technical drawing text, which focuses solely on mechanical drawing projects, holds little interest for these students. In recognition of the diverse career interests of our students, Technical Drawing 101 includes projects in which students create working drawings for a mechanical assembly as well as for an architectural project. By focusing on the fundamental building blocks of CAD, Technical Drawing 101 provides a solid foundation for students going on to learn advanced CAD concepts and techniques (paper space, viewports, xrefs, annotative scaling, etc.) in intermediate CAD courses. The CAD portion of the text incorporates drafting theory whenever possible and covers the basics of drawing setup (units, limits, and layers), the tools of the Draw, Modify, and Dimension toolbars, and the fundamentals of 3D modeling. The videos progress to more advanced topics where the authors walk students through completing several of the projects in the book. In these videos the authors start off by getting students comfortable with the user interface and demonstrating how to use many of AutoCAD's commands and features. The authors have also created extensive video training (178 videos, 26 hours total) that is included with every copy of the book.

Both mechanical and architectural projects are introduced to capture the interest of more students and to offer a broader appeal. But unlike the massive technical drawing reference texts on the market, Technical Drawing 101 aims to present just the right mix of information and projects that can be reasonably covered by faculty, and assimilated by students, in one semester. Technical Drawing 101 covers topics ranging from the most basic, such as making freehand, multiview sketches of machine parts, to the advanced-creating an AutoCAD dimension style containing the style settings defined by the ASME Y14.5-2009 Dimensioning and Tolerancing standard.
