This means that the Brep model is instantly available as soon as you leave the Freeform environment. Instead of converting to a Brep on command, Inventor constantly calculates the T-splines surface in the background. One big difference is how the Inventor implementation handles conversion to Brep’s. What you get in Inventor 2015 is the most basic set of tools that make Freeform modelling practical. The Freeform toolset in Inventor 2015 is the very first implementation of T-Splines inside inventor, so not all the tools from the original Rhino version have been ported over yet. How is Freeform different to T-Splines in Rhino or Fusion 360? They are not parametric and there is no History (Apart from the UNDO tool!). Freeform surface models are edited using direct manipulation. How is Freeform different other Inventor tools?įreeform in Inventor 2015 is actually a completely separate modelling environment. This really helps Inventor to process the T-Splines surface quickly when we want to convert our Freeform model back into a Brep solid. The ability to add more control points and more control splines in a limited area is really helpful in allow us to add detail, without adding mathematical complexity to the surface.

You can see T-Splines subdividing faces in this excerpt from my Video tutorial series ‘ Mastering Inventor T-splines‘. The clever bit about SubD modelling in T-splines is that you can subdivide individual faces, so that you only need to add complexity to your surface where you want additional detail.
