The Death of the Draftsman. The Death of the Draftsman. Where has all the talent gone?”. With the introduction of MBD (Model Based Definition). Boeing was convinced, since it didn’t need drawings any more, it didn’t need. The Drafting group was dissolved along with the Document Control. Dassault that their PLM system based. Catia 5 could replace and manage the complete engineering system. The. draftsman, now called engineering tech, is being replaced with the degreed. CAD designer, engineer. The "Draftsmen" are being allowed to disappear. Computer-aided design (CAD) is the use of computer systems (or workstations) to aid in the creation, modification, analysis, or optimization of a design. CAD software. CADDS 5 16.1 and Optegra 16.1 Patches - English Published: 11-Sep-2017 Operating system patches that must be installed before running CADDS 5 16.1 F000 or Optegra 16. Computer-Aided Manufacturing (CAM) can be defined as the use of computer systems to plan, manage, and control the operations of a manufacturing plant through either. Prev - 4. CAD software history, 1986-1989. 5. CAD software history, 1990-94 UNIX to Windows NT. The CAD software market entered the 1990s in conflicted turmoil. · For readers of A Certain Age, this may bring a tear to the eye. Reports have been circulating of the decision by Oracle to lay off a significant portion of. You can see that the basic job of creating documentation. I wonder if the young. Cadds 5 Software Free DownloadAs a Boeing trained draftsman I was shocked. Knowing. the responsibility of drafting group. There really is no job description of an Engineering Tech. The community colleges are still offering drafting class. I was up in arms, no group of engineers, could or. Drafting had no spokesman. Draftsmen do not have 4. BCS (Boeing Computer. Services), who is now in charge of the all mighty PLM. They were a pain in. I can only imagine the arrogant power they wield today. Articles. NURBS and CAD: 30 Years Together. Dmitry Ushakov. In the outgoing year engineering celebrates a remarkable anniversary – thirty years of. PTC provides technology solutions that transform how products are created and serviced, helping companies achieve product and service advantage. Most drafters are hourly employee’s one step above a blue collar. Their education was basically a 2 year AA degree from a community. Mine was a condensed drafting training program run by Boeing and sponsored. Here is a quote from an associate on Linkedin that. Hm.. Can anyone show a better example of what happens when an.
Sure, the allure of cutting costs is. Matthew Sawtell. I have to add to Matthews statement that the introduction of the 3. D model. as the basis for our design, has changed the process completely. Eliminating. the the manual drawing or layout in the beginning, and now using 3. D CAD has made design a single step. The skills. of the designer with the orthographic drawing or layout are not needed and I. The Draftsman is not needed. Ref: The Death of the Drawing. But per the definition below we still need drafting. Do we need a new. Drafting"The systematic representation and dimensional. As you can see the above description can include 3. D. design, I will get into that later. Drafting is an ancient art. Dating back centuries. What is a Draftsman? Draftsman made drawings! Prior to 3. D CAD we made drawings. Yes, we can create. D drawings today by creating views or instances of the 3. D. model and adding dimensions and annotation. These are not drawings, they are. I call the AID (Associated Information Document). Yes there is the Autocad. What is a drawing? A. drawing is a document that describes the part/assembly in an. These were the reason draftsman were. They were time consuming and an engineer’s time was much more valuable. This document was used to. It was in a standard format that. When done correctly stood alone without a need. Engineering's total purpose is to deliver concise, complete and. There was also a standard procedure for handling the. The draftsman would work with an engineer or designer or develop. He/she would actually do the design on a layout. The drawings had to. Even though the draftsman may have. What is the Checker? The checker was an experienced draftsman whose only. He/she would mark every dimension and note. Nothing was not marked. When the checking. This process was as important as the design and drawing. This is not some quick review this is a time consuming review of the design. If this step is bypassed or ignored the resulting costs for a missed. Below I. have described the revision process handling errors. Just think of the cost. It has always been a rule "Measure twice, Cut once". All draftsman knew and appreciated this, learning many lessons from the. Checkers input. Murphy's law was the draftsman's arch enemy! The draftsman learned from every job. Soon he/she. became very knowledgeable in the standards of their industry. They became the designers of the products. Every large manufacturing company. Even though the drafting group was part of engineering. This is another reason for creating a complete AID (model based drawing) from our. MBE. It is much easier to review and check. I will go into this later. What was the drafting group? The drafting group was. Sometimes a large company, like Boeing, would. Drafting was all about standards. The drafting group was responsible for creating the. Much of the design was done by a one or a few draftsmen under the. Drafting was responsible for releasing completely. This was a standard process. The drawing. was taken around for review and approval by specific engineering groups. The title block had. The drawing name and number and. It also included UOS (Unless otherwise. When the title block was signed off the engineering was complete and it was. Document Control who created the blue prints and delivered it. Then the originals were stored in. Yes, actual vaults. What is Document Control? It was basically an admin group that would take the. This group like. Drafting was associated with but separate from engineering. Today this is. part of engineering included in the PLM system. But it only handled the. PLM handles the. native CAD data as standard deliverables. Data inside engineering and documents. This is why PLM will never succeed. A Native CAD file cannot be used. What is purchasing? Purchasing is the department that would deliver the. Purchasing would keep track of the revisions and where the parts were used. The drawings would include used on information. For example, Boeing would. Many times one drawing would have many different. This is another place where PLM has failed. Due to the way the Pro/e. While this may be. They should be in one single file where all information is. I describe a more. What is manufacturing? I know this seems like a silly question, but as I. MSME and PHDs that are so called PLM experts thinking. Draftsman they. have no clue. They sit in some ivory tower and just think how it should. None have ever created a design or a parts list and probably never. I chuckle how they use. BOM (Bill of Materials) never knowing that was basically an architectural. I never saw it until working with Autocad, and now it seems to be part. Sadly the PLM folks are trying to. But luckily there is. Manufacturing "has" to deliver or they don't get paid. Ref: PL or BOM? Manufacturing takes the drawing and creates. When the parts are made they are inspected to the drawing and. Manufacturing. is not part of engineering or drafting. Once they get the drawings they. Many companies have planning groups that manage the manufacturing process. At assembly, engineering may or may not supervise the. After that engineering will step out of the picture unless there are. Problems”!! Sometimes engineering is not present at assembly. Imagine an aircraft assembly line. The plane starts down this line. There is. a part that doesn’t fit or the assembly instructions are vague. They have a. liaison engineer that instantly handles the problem with a temporary fix. Nothing can hold up the assembly line. He/she will write up a rejection tag. This rejection tag is sent to the. What is a revision? The responsible group gets the rejection tag and. Why a draftsman? The drafting group is the most. The draftsman. investigates the problem and working with the lead engineer and creates a fix. How are revision handled? The original drawing can be difficult to change every time there. Engineering needs a fast way. Manufacturing is happily. It. is very important to get that change to them as fast as possible. Many times manufacturing was. What is an ADCN? Advanced Drawing Change Notice. This was a document. They were released to Document Control and handled like initial. This is where MBD totally fails. Ref: The ADCN vs MBEWhat is the DCN? Drawing Change Notice. This was when the original. Sometimes the correction is too large to define. ADCN. Also it maybe done just to incorporate the outstanding ADCNs when. Drawings were stored in vaults, yes real vaults. You would. go to the vault and check out the original drawing. Again a DCN is released the same as the initial release to Document. Control. All of the above process were done by Drafting. Engineer were never involved in this process except for the review and. They felt assured that the drawings were done. That is drafting in a nutshell. Enter 3. D CAD! In. D CAD it was the same as what I described above. The. draftsman did all of the design under the scrutiny of an engineer. An. engineer was always involved with the design and was always the last word. I was introduce to 3. D CAD in 1. 98. 2 with Computervision. CADDS 4. 3. D CAD was in the realm of the draftsman. Engineers did not have time. D CAD. Draftsmen continued to do the design and creating drawings. But we did not create drawings we created what I have coined AID (Associated. Information Documents). Yes they looked like. They would be checked and corrected by revising the 3. D model and AID. Ref: The 1. D CAD - The Beginning. Ref: The Death of the Drawing. I get criticized for making the distinction between. AID. But you just do not create a drawing when you. D. I created manual drawings for years, and the AID is something very different and much, much easier. On a drawing you design by "drawing" separate. D plane. I even hate to use the 2. D. reference, since it is so obviously redundant. We did the manual drawings on a drafting. D drafting board would be just silly. If. you could read a drawing you could see the real world 3. D part. Today, I have. Isometric view just to understand the part. For years 3. D CAD was in the realm of the draftsman. I. would like to say that when Pro/engineer showed up in 1. D CAD. But it wasn’t so. While on contract at Solar. Turbines in 1. 98. D CAD draftsman go. They told the engineers. Computervision CADDS 4. X. They balked but. Solar management said “Get on the CAD system or you are fired”. I was the. last of the contractors left and trained the engineers. They became very. I was introduced to PC based 3. D CADKEY while on. Boeing 7. 47 Flight Deck. I was told there was a PC based 3. D CAD. system on a couple of Compaq’s. It sparked my interest since I was working. CADKEY was 3. D wireframe and very similar to Computervison. Bye Bye Solaris, it seems. For readers of A Certain Age, this may bring a tear to the eye. Reports have been circulating of the decision by Oracle to lay off a significant portion of the staff behind its Solaris operating system and SPARC processors, and that move spells the inevitable impending demise of those products. They bore the signature of Sun Microsystems, the late lamented workstation and software company swallowed up by the database giant in 2. So why might we here at Hackaday be reaching for our hankies over a proprietary UNIX flavour and a high- end microprocessor, neither of which are likely to be found on many of the benches of our readers in 2. To answer that it’s more appropriate to journey back to the late 1. TV set as a monitor. If you received a technical education at a university level during that period the chances are that you would have fairly soon found yourself sitting in a lab full of workstations, desktop computers unbelievably powerful by the standards of the day. With very high resolution graphics, X- windows GUIs over UNIX, and mice that weren’t just used for a novelty paint package, these machines bore some resemblance to what we take for granted today, but at a time when an expensive PC still came with DOS. There were several major players in the workstation market, but Sun were the ones that seemed to have the university market cracked. You never forget your first love, and therefore there will be a lot of people who will never quite shake that association with a Sun workstation being a very fast desktop computer indeed. Their mantra at the time was “The network is the computer”, and it is the memory of a significant part of a year’s EE students trolling each other by playing sound samples remotely on each other’s SPARCStations on that network that is replaying in the mind of your scribe as this is being written. A Raspberry Pi with a Raspbian desktop probably outperforms one of those 1. SPARCStations in every possible way, but that is hardly the point and serves only to demonstrate technological progress. It feels as though something important died today, even if it may be a little difficult to remember what it was when sat in front of a multi- core x. POSIX- compliant operating system running upon it. Unsurprisingly we’ve featured no hardware hacks with such high- end computing. If you’d like to investigate some Sun Microsystems hardware though, take a look at the Centre for Computing History’s collection.
