__NOTOC__
  
−
According to Wikipedia: "Model-based definition (MBD), sometimes digital product definition, is the practice of using 3D models (such as solid models, 3D PMI and associated metadata) within 3D CAD software to define (provide specifications for) individual components and product assemblies."

−
An important feature of VTube is the ability to import generic solid models of tube shapes in the STEP or IGES formats and then calculate centerline and bender data from those solids.

==Benefits==

−

−
The benefits of MBD are significant:
+
−
 
+
−
# Creating bender data from a solid model '''eliminates keyboard entry of centerline data for the nominal or master part'''.  This is a huge benefit considering many mistakes are made due to misreading or mistyping of numbers from one data grid to the next.<br><br>
+
−
# In most cases, importing data from a solid model is much faster than keyboard entry - even if the keyboard entry is perfect the first time.<br><br>
+
−
# Model-based Definition gives instant visual feedback and confirmation that the part is correct - because the derived parametric model is '''superimposed on top of the imported model'''.<br><br>
