Hard Copy to Digital Transfer: 3D Models that Match 2D Maps
Get PDFThis research describes technical drawing techniques applied in a project involving digitizing of existing hard copy subsurface mapping for the preparation of three dimensional graphic and mathematical models. The intent of this research was to identify work flows that would support the project, ensure the accuracy of the digital data obtained, and provide a means of capturing, realizing, and extending the value of an existing investment in subsurface mapping. Mapping used in this project was in hard copy format. Control points for use in digitizing were converted from local coordinates to plane coordinates based on a defined map projection. Since mapping done in this work was to meet National Map Accuracy Standards, calculation of acceptable root mean square digitizing error was necessary and is demonstrated. Two methods are discussed to ensure quality control in digitizing. Preparation of base maps showing drilling data provides a means of estimating map accuracy. Map precision, however, is shown by comparing the congruence of contours as digitized and contours as obtained from the digital model. Where congruence is lacking, the digitizing of supplemental contours or direct editing of the grid itself is required to precisely constrain the 3D model. Efficient work in this project was heavily dependent on use of standard techniques of engineering graphics. To expedite digitizing, a common layering scheme was developed for all oil fields mapped. Control points used in digitizing were selected so as to be common to all mapping, even where multiple maps were involved. In addition, the use of a common map format, color scheme, lettering style, and included metadata materially expedited the work. Finally, the conduct of the work in defined stages provided immediate work products from the project. This facilitated identification of needed changes early in the project and supplied accurate data as soon as digitizing on a specific field was complete

Get PDFIn graphics our goal is clear; help students learn to visualize so they can ideate with themselves, communicate graphically with others, and communicate according to industrial standards. How we reach these goals is ever changing. In my thirty-four years of teaching graphics the most significant change in the curriculum has been the introduction of 3-D modeling. It has fundamentally changed the way students learn to visualize. But even with this fundamental change my preferred method of teaching graphics has not changed. The only way to learn graphics is to draw and/or model. My teaching philosophy reflects this principle. I call it my “Sink AND Swim” principle of teaching graphics. In a graphics course students do not want to listen to you talk about drawing – they want to do it! I believe students learn and retain graphic principles best when they are allowed to struggle with a problem on their own. After giving students the minimal amount of information to get started, I like to use my three favorite words in teaching “go to work”. This gives me the opportunity to become more of a coach and help students with their struggle. When they begin to sink we can reconvene and talk through the problem a little more. Then the process repeats itself until the task is completed. Ideally I prefer to have all my lecture/lab time entirely in the lab so I can give mini lectures when they are needed

No full textWe just finished our 65th midyear meeting in Houghton Michigan hosted by Michigan Tech. Special thanks go to our general chair Sheryl Sorby, and our co-chairs Amy Hamlin and Norma Veurink for being such welcoming hosts. As suggested on one of the postcards in our meeting packet, Houghton is not the End of Earth but simply two miles from it. For many of us Houghton may be the closest we will ever get to the Arctic Circle. Despite our apprehensions, Houghton turned out to be a beautiful setting for a midyear meeting and the Michigan Tech “girls” did a fantastic job
2010 Distinguished Service Award
No full textThe recipient of tonight’s Distinguished Service Award has been a member of ASEE for over forty years. During that time, he has taught Engineering Graphics and Descriptive Geometry at Universities in three different states. His loyalty and dedication to the Engineering Design Graphics Division is underscored by his service as a past Division Chair, and as Program Chair for numerous EDG midyear meetings going back three decades. A special distinction concerning tonight’s ceremony is that our recipient’s father received this same Distinguished Service Award 34 years ago. In addition to an accomplished career as a college educator and author, our recipient has served his country both in active Army duty, including a tour in Vietnam, and in the U.S. Army Reserves, attaining the rank of Colonel. It is my pleasure to introduce a long-time colleague and humble servant of the Engineering Design Graphics Division, a true American patriot, and a fellow citizen of the state of Texas, Ron Paré.
