The Lanly Company designs and builds custom heat processing equipment for an extensive range of industries.
Like many industrial machinery makers, The Lanly Company (Lanly) has been using 2D computer-aided design (CAD) for decades. Despite having access to 3D modeling tools, Lanly’s drafters shied away from solid modeling due to its complexities. But a new way to design in 3D provided a major productivity boost for the industrial oven and furnace manufacturer.
“I knew what 3D could do for us,” says Steve Zimnoch, project manager at Lanly. With a background using 3D CAD systems including Pro/ENGINEER® software, SolidWorks® software and Solid Edge® software, Zimnoch led a nine-month evaluation of several systems and determined that Solid Edge possessed the best technology to transition from 2D to 3D.
That new way leverages synchronous technology, a core component of Solid Edge from Siemens Digital Industries Software. “CAD based solely on history-based design confuses 2D users; there are so many steps required. Solid Edge with synchronous technology reduced the complexity of moving to 3D,” Zimnoch says.
Lanly creates new machine designs from standard structural steel parts. Using synchronous technology, Lanly reports that design is 15 to 20 times faster than using traditional history-based CAD.
Cleveland, Ohio-based Lanly, founded in 1938, designs and builds industrial ovens, industrial dryers, material handling equipment, process control systems and custom heat processing equipment. Lanly’s equipment is used in many applications and industries including aluminum, board and insulation, ceramics, chemicals, coating processing, electrical, food processing, investment casting, lamps, refractories, rubber and plastics, steel heat treating and textiles. Lanly’s core business attributes include high-quality workmanship, reducing unit costs, on-time machinery delivery, faster drying and curing processes, and control system integration.
Demands for higher production, faster systems, and tighter uniformity are conditions met by the application of high-velocity heated air. This technology is often referred to as air impingement processing. Lanly is a leader in air oven technologies, and its mechanical engineers have developed an efficient, high-velocity tube air discharge duct system. This air impingement system is used to speed drying and curing.
“The engineering of the 200- to 1,200 degree high-velocity airflow in the systems is very important. Our engineering challenges are basically using the CAD software to develop the structural steel and the sheet metal conveyor systems and equipment,” says Zimnoch.
The use of 2D design techniques created many design errors such as part interferences and outdated drawings after changes were made. “With 3D, now we have an assembly set of maybe 100 drawings. That entire assembly drawing set gets updated once you make your changes. In solid modeling, you can actually see the interferences and where you can get around those. Also, the ease of creating drawings allows you to put on more dimensional information so the fabrication of the parts can be completed faster and more accurately,” says Zimnoch.
In 2011, Lanly found a new way to maximize its 3D design productivity. Lanly began using Solid Edge in 2000, but in a limited way only for plant layouts. Once Lanly began using synchronous technology, the rest of the designers who had stayed with 2D AutoCAD moved very easily to 3D.
Zimnoch worked in history-based 3D CAD but switched to synchronous technology because “it’s so much easier and faster.” Lanly engineers have been able to accelerate new designs, revise existing models faster, and achieve better re-use of data created in other CAD systems. History-only CAD systems use a feature-based approach to creating and editing models, which requires a lot of preplanning time to take care of unforeseen changes that frequently arise. Conversely, history-free modeling is fast, but featureless, with limited automated design capability. Synchronous technology provides the best of both with highly automated features and dimensions that facilitate flexibility and near-instant performance.
“When creating a part using synchronous technology, you’re only sketching the box and then extruding it. With ordered (history), you’re creating a sketch and then you’re manipulating that. Synchronous technology is a lot more fluid and it allows you to go seven-times faster,” says Zimnoch.
When Lanly hires new designers, they find it much easier to make changes to existing parts and assemblies because they don’t have to spend time studying the feature tree to determine how the models were originally built. In many cases, part and assembly models were created by designers who had left the company.
“In history-based CAD, it would take you maybe 15 or 20 minutes to go back and look at the history tree, and in synchronous technology it takes you maybe a minute to a minute-and-a-half to create those same edits,” says Zimnoch.
Another downside to just using historybased design, Zimnoch notes, occurs when a customer wants a part moved to a different location on a machine. “You would have to go back into the history tree and make those edits, which sometimes was very cumbersome. Now with synchronous technology, you can look at what the customer is asking and make an edit so that it fulfills what he has asked, without spending time looking at what you had done to create that part,” he says.
Synchronous technology also helps Lanly efficiently re-use design data created with other CAD systems. For example, with oven equipment Lanly uses many part models from vendor or third-party website resources. “That allows us to pick up a sprocket or motor model and place them into our designs,” Zimnoch says. “If these ‘dumb’ featureless part models need to be rotated or moved – to place an electrical connection box on the other side of a model, for example – it’s very difficult to do in an ordered history environment; practically impossible,” Zimnoch says.
“If you do it in synchronous technology, you’re using and selecting the faces that you want to manipulate and you can make changes. You’re not really changing the customer’s design or the vendor’s design – you’re changing just the components on that vendor piece.”
Lanly leverages the advanced technologies of Solid Edge and also the vast expertise of the large and growing Solid Edge online community site. The Solid Edge community is a set of forums, blogs and knowledge bases where people ask, share, read, search, learn and comment about Solid Edge topics.
“The Solid Edge community is a very, very useful tool for us,” Zimnoch says. “I just saw the blogs the other day on the use of the Alt key, for example. I’ll have a weekly meeting with the rest of the design team and we’ll go over what I’ve found in the community and present that to them. It’s a very good tool for me to help educate everyone else in our company.”
