Many computer users think that traditional 3D modeling programs such as Blender or Maya have a high learning curve.
One popular application is rapid modeling of low-detail objects for use in prototyping and design work.
The user is never required to interact directly with the vertices or Nurbs control points.
A number of papers on this topic are presented each year at the ACM SIGGRAPH conference.
The European graphics Association Eurographics sponsored four special conferences on sketch-based modeling: Since 2007, Eurographics and ACM SIGGRAPH have co-sponsored the Sketch-Based Interfaces and Modeling Symposium which in 2011 became a part of the Expressive Graphics Symposium The Eurographics/SIGGRAPH Joint Symposium on Sketch-Based Interfaces and Modeling was held on
