#SEU12 - 101 auto cad legacy changing 2d drawings into 3d reality in a flash - dan swartz


Published on

This session will demonstrate the speed and accuracy of converting a 2D AutoCAD sketch into a 3d part. New or experienced users will be exposed to the ease, speed and accuracy of how a 2d sketch becomes a modifiable 3d part with Synchronous Technology SheetMetal. This session is geared towards Designers and developers who need to bring in parts from an already designed product that's still in AutoCAD. The goal is for attendees to learn and understand what Synchronous SheetMetal can do for their designs and that there is no difference between starting from scratch or with a 2D sketch. This presentation will also include some live demonstrations to better show key concepts for conversion.

#SEU12 - 101 auto cad legacy changing 2d drawings into 3d reality in a flash - dan swartz

  1. 1. Dan Swartz • Prior to 2000, 15 years in construction • 12 Years With Venture Products, Inc. • Product Support Manager • Areas of Responsibility • Product Updates • Production Problem Analyst • ECC Process Manager • CAD Administrator • CAD Setup • File Management • ERP Database Administrator • Product Design • Product Testing • Mechanical • Sound
  2. 2. Roscoe Lehman • BSME – University of Akron • 2 years co-op work as an Engineer • DesignDemo Tech • Research • Testing • Used Pro E 2001 CAD Software • 6 Years With Venture Products, Inc • Product Development Engineer • Areas of Responsibility • New Concept Research • Data Technician Programmer • Product Design • Product Testing • Programmer using Labview and National Instruments Hardware • Mechanical • Sound & Vibration •Hobbies • RC Planes and Helicopters • Motorcycles & ATV’s • Music
  3. 3. Who is Venture Products, Inc. ? • Venture Products (VPI) is located in Orrville, OH (about 45 minutes south of Cleveland) • VPI manufactured agricultural feeding equipment until late 1990’s, but expanded into the turf equipment business in 1998 with the addition of the Ventrac line • 90 employees with 2 Locations: • Plant 1 – Fabrications, Welding, R&D, and Shipping • Plant 2 – Powder Coating, Assembly, Parts and Service • VPI is currently in the process of building a new 115,000 sq ft facilityManufacturing • VPI has 4 Robotic Welders, 1 CNC Laser, and 2 CNC Brake Presses • We do off-line programming for all our CNC Machines using CAD/CAM Software. • 75% of the parts we design are sheet metal. (20ga up to 1/2”) • On average, we cut 4,500 lbs of steel a day
  4. 4. What is Ventrac?The Ventrac line of equipment is VPI’s brand of turf equipment. Products include tractors andattachments • There are 2 sizes of tractor power units, both having multiple engine options including gas and diesel, and ranging from 21 to 31 horsepower. • There are over 30 different attachments that will interchange on the same tractor: mowers, snow blowers, dozer blades, power blowers, and many others. • Many accessories are available – Dual wheel kits, Rear 3 point, Cab, etc • Customers include commercial contractors, municipalities, golf courses, and large acreage homeowners.

  6. 6. CAD History• AutoCAD used since 1986A brief overview of design process (Prior to Solid Edge) • A concept is born and design is started • A 2D layout is made of the product • Parts are pulled out of the sketch and saved individually so parts can be made • Prototype parts are made • Product welded and/or assembled. • Torch and drill used extensively to make parts fit or add a hole that was missed • Changes made to parts • More prototypes made. More Changes • Up to 10 or 12 unique prototypes could be made before product went to production.
  7. 7. Challenges:• Very difficult to see in the 2D view how things fit together• Large amounts of prototype parts made• Mega amount of changes often continued for a year after production started• When changes were made, it was often hard to see how things fit and holes line up, Co-planar faces didn’t align well, and so prototypes of changes were required most of the time!• Formed parts frequently did not match what was designed.
  8. 8. • For years, many parts were assembled or welded together even though they did not fit properly.• Manuals………… • Parts were designed in 2D Only. Creation of ISO Views for manuals was difficult and time consuming. • Pictures had to be taken to show how to adjust or assemble each product. Most of the time, this couldn’t be done until after the start of production• Assembly procedures – with AutoCAD, we had limited capability to create instructions for assembly
  9. 9. AutoCAD Replacement evaluation: • 3 different CAD programs were evaluated • Since we are 75% Sheetmetal, conversion of AutoCAD drawings was a significant part of the evaluation. • Some CAD competitors failed and couldn’t convert parts • Others wanted to have our parts for a couple of days so they could convert, then show us. • Solid Edge, • Had the easiest time converting sheetmetal parts. • Had the best User friendly Interface
  10. 10. How Solid Edge is Used• Our lead engineer/owner develops concepts and designs in AutoCAD. • Complete 2D layout • When ready to build a prototype, He pulls individual parts out and puts them on one big page. • After the concept has been built and tested, the project is transferred to development. Individual parts are converted to 3D and assembly files are created.
  11. 11. • Creating a 3D Sheetmetal part from AutoCAD • At this point – it doesn’t matter whether a part is converted from AutoCAD or Created from Scratch in SE. • Parts are converted from 2D to 3D in minutes • Convert in Synchronous mode. • You (the user) have the option to work in the ordered (traditional) mode if that is YOUR preferred way. (However, you won’t be as efficient as when working in synchronous!) Live Demo
  12. 12. Known problems with AutoCAD Legacy conversion • Corner Treatment missing • Double Lines • Disconnected endpoints • Minimum Flange length • Features too close to break line
  13. 13. An assembly is created with 3D parts • Using the “Relate” commands, faces are pushed and pulled to ensure perfect mating surfaces • Holes can be moved to ensure they are in perfect alignment! • Interference Checker is used to show interference between parts. Live Demo
  14. 14. • 2D drawings are created for production that are linked to the part files.Live Demo• DXF’s are created for the CNC programming • We are evaluating new programming software that will accept Solid Edge Sheetmetal parts in 3D form.• At the assembly level, exploded views can easily be created for your 2D drawing for manufacturing• Since the 3D parts and assemblies are already created, manuals can be created without drawing any additional parts or any extra assembly time.• Top level assemblies can also be rendered to show a photo realistic view of the product to use in manuals or publications. Parts can be hidden to show better detail of select areas!
  15. 15. What Value has Solid Edge brought to the table?• Parts mirror reality very closely. If SE says it’s going to interfere, it will.• Time from start to first proto is longer than if AutoCAD were used, but in the end Solid Edge saves far more time and resources.• In the long run, With Solid Edge, we can put a product into production 20 – 30% quicker and have less changes after the pilot run.• Welding is able to assemble weldments easier, and make a better quality part.• Drastically reduces time troubleshooting problems because we know what the parts and weldments are supposed to measure• Bill of Materials can accurately be exported to help with Inventory control• Manuals are created faster and have a more professional look• Assembly line leaders are able to make procedures for “How to assemble” before production starts and show detail better than with pictures.
  16. 16. With a 3D assembly • Round Table Discussions – Design reviews with Service, Assembly Leaders, Production Managers and anyone else who has input into the design are very beneficial • Using PMI notes…… • The area’s in question can be tagged and the engineer has a complete point by oint meeting action sheet for later review • Notes can be added for desired changes • Parts can be hidden to show specific areas more clearly. This makes it much easier to explain problems or concepts to other departmentsCreate a 3D PDF • Ideal for sending a 3D assembly to a customer that is fully functional but at the same time, protects design integrity! Give added clarity to the product as parts can be hidden just as in Solid Edge. • Can also be used as a better collaboration tool with other departments within our company!Future Tools • Get Insight (File Management) up and running.
  17. 17. How do you get started? 1. Get the latest version of Solid Edge. 1. You will not be efficient in conversion and be able to do what you have seen here today unless you begin using Synchronous Technology! Synchronous Technology has changed the CAD world forever! CAD will never be the same. 2. Always stay up-to-date with the latest release and Maintenance Packs 1. If you are renewing your SE license, you are already paying for the latest and greatest anyway. Install it. 2. Solid Edge does a great job with releasing Maintenance Packs to fix the little issues that arise along the way, and they are always very well tested before being released
