Version 2.9.17 of VTube-STEP was released on December 21, 2018.
The major new feature in this version is that we've added a single-button press model-to-parametrics calculation feature called Autobuild Parametrics. Previously, VTube-STEP always required that you perform a process called "Collection" where each straight was selected one at a time.
The new Autobuild feature is designed to skip the collection process by handling "clean" models. Clean models are tubes with no brackets, forms, coping, or drilled holes. Many of our customers use clean models anyway - so it makes sense that we added this feature.
I was expecting this new method of calculating parametric bender data to be faster - but I didn't expect this much faster. Autobuild Parametrics is at least 5 times faster than the legacy Collections process. On tubes with more bends, the speed difference is even greater.
You'll still want to keep the legacy collection process handy for models that are not clean. But for those that are only importing clean tube models, then I recommend that you start using Autobuild Parametrics as soon as possible. You'll be glad you did.
