Traxxas speeds up their designs with T-Splines
The solutionJaime has been using T-Splines since version 1.0, although at the beginning, incorporating T-Splines in his design process was challenging. Most of the designs he saw on the T-Splines web site were very organic, while he required sharp lines and corners in his designs.
Two things significantly increased his use of T-Splines: first, the realization that smooth T-Splines surfaces can be mixed with regular NURBS in a model; and second, the significant increase in functionality released in T-Splines v2. The new feature in v2 that had the greatest impact on Jamie’s work was the ability to toggle between seeing the smooth T-spline surface and a boxy mesh representation of the surface. This new way of viewing the model was a real breakthrough, as it allowed him to visualize more clearly and quickly what the final shape was going to be.
“I can make changes to the model in box mode just by creating and pulling lines at blazing speeds, and it allows me to experiment with forms that will give me further ideas.”
The ‘Slash 4x4’ truck model displayed in this case study represented Jaime’s most recent challenge, and T-Splines made a critical difference in meeting the deadline and all the design requirements.
Where T-Splines has really made a difference for Jaime is the ability create a “hybrid model” that mixes T-Splines with regular NURBS surfaces. The easily modifiable T-Splines surfaces are used for the smooth aerodynamic design of the car body, while the NURBS surfaces can be used to represent the fixed defined reference surfaces.
Jaime can get the design exactly as he envisions it, and pushing and pulling to mold the T-spline surface is much faster than making lines to create NURBS surfaces. He can quickly respond to design change requests, even if they come just hours before the deadline.
On a typical design project, adding T-Splines to the process has reduced the design time from weeks to days, and has allowed him to present more design options for review.
Future DirectionThe ‘Slash 4x4’ project was a great success. In the February 2010 issue, Xtreme RC Cars magazine reviewed the car and says: “The new body looks awesome.”
T-Splines has become a standard part of the design process at Traxxas, helping Jaime be more innovative and productive. In several planned projects, he foresees using T-Splines for almost 100% of the workflow from concept to final design.
