MADISON — Siemens Corporation selected Leann Martins and Yuyun Chen’s computer-generated designs for the Siemens Global Image Calendar.

“Siemens holds a global contest each year. Students and mostly software professionals submit their three-dimensional renderings/designs using Solid Edge, a Siemens product,” Jessye Gaines said. Gaines teaches in the Engineering for Tomorrow (E4T) Academy at Bob Jones High School.

“For the first time, we have two students featured in the same calendar,” Gaines said. In 2012, Siemens honored Jacob Locke of Bob Jones as its first high school student.

“My juniors in spring 2012 submitted their 3D renderings to the contest,” Gaines said. “We compete against college students and professional CAD modelers from around the world. The only high school students ever selected for this calendar are from Bob Jones.”

Bob Jones engineering students learn to use Siemens Solid Edge ST4 modeling software. “Siemens is due to release Solid Edge ST6 this year. Because of our students’ reputation and caliber of work, Siemens (will host) senior interns at their Huntsville location to test the ST6 software before its global release,” Gaines said.

Martins spent about 150 hours to design a 3D home clock. “We actually own the clock. It’s sitting on our mantel in our living room. It’s roughly 10 inches tall. Various gears turn constantly,” she said.

Martins modeled the front face’s large gear and 12 background gears. Three layers of framing connect to form the base. She designed both a realistic image and another colored image that highlights different pieces of the clock.

“We had a few weeks in class to work on the CAD model, but I had to work several hours at home to finish,” Martins said. She will attend Auburn University this fall. Her parents are Marcelo and Rosely Martins.

Chen used her flute with its intricate keys and framework as her modeling object.

In coming weeks, a Siemens representative will visit Bob Jones to present Chen and Martins with their awards.
