Sketch2CAD: Sequential CAD Modeling by Sketching in Context [article]

Changjian Li, Hao Pan, Adrien Bousseau, Niloy J. Mitra
2020 arXiv   pre-print
In our system, this context corresponds to a partial CAD model, inferred in the previous steps, which we feed along with the input sketch to a deep neural network in charge of interpreting how the model  ...  We present a sketch-based CAD modeling system, where users create objects incrementally by sketching the desired shape edits, which our system automatically translates to CAD operations.  ...  The work of Niloy was supported by ERC Grant (SmartGeometry 335373), Google Faculty Award and gifts from Adobe, and the work of Adrien was supported by ERC Starting Grant D3 (ERC-2016-STG 714221), research  ...

Particularly, the form of CAD models having a sequence of extrusion cylinders -- a 2D sketch plus an extrusion axis and range -- and their boolean combinations is not only widely used in the CAD community  ...  Reverse engineering from a raw geometry to a CAD model is an essential task to enable manipulation of the 3D data in shape editing software and thus expand their usages in many downstream applications.  ...  Sketch2cad: Sequential cad modeling by sketch- [36] Charles R Qi, Or Litany, Kaiming He, and Leonidas J ing in context.
