CAD modeling, despite being the industry-standard, remains restricted to usage by skilled
practitioners due to two key barriers. First, the user must be able to mentally parse a final …

We present SymbiosisSketch, a hybrid sketching system that combines drawing in air (3D)
and on a drawing surface (2D) to create detailed 3D designs of arbitrary scale in an …

We propose a method for reconstructing 3D shapes from 2D sketches in the form of line
drawings. Our method takes as input a single sketch, or multiple sketches, and outputs a …

3D modeling remains a notoriously difficult task for novices despite significant research effort
to provide intuitive and automated systems. We tackle this problem by combining the …

We introduce an interactive technique for manipulating simple 3D shapes based on
extracting them from a single photograph. Such extraction requires understanding of the …

As 3D technology, including computer graphics, virtual reality and 3D printing, has been
rapidly developed in the past years, 3D models are gaining an increasingly huge demand …

Sketch-based modeling strives to bring the ease and immediacy of drawing to the 3D world.
However, while drawings are easy for humans to create, they are very challenging for …

True2Form is a sketch-based modeling system that reconstructs 3D curves from typical
design sketches. Our approach to infer 3D form from 2D drawings is a novel mathematical …

Product designers extensively use sketching to reason and communicate about 3D shapes,
as documented in popular design sketching textbooks [Eissen and Steur 2008, 2011; Pipes …

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 …
