We present an image guided pen-based suggestive interface for sketching 3D wireframe models. Rather than starting from a blank canvas, existing 2D images of similar objects serve as a guide to the user. Image based filters enable attraction, smoothing, and resampling of input curves, and allows for their selective application using pinning and gluing techniques. Current digital 3D modeling software enable the creation and manipulation of extremely sophisticated geometric objects, and have been widely adopted by practitioners in industry. The skills designers, artists, and architects have in working with various rich physical media is simply not leveraged; instead, a whole new skillset has to be developed for working with the digital tools. Given that the fidelity of current digital tools often do not approach the physical. Spatially Integrated Construction Planes 3D models in our system are created by drawing the relevant 2D profile curves on orthographic construction planes from the three primary viewpoints – top, side, front. Rather than viewing these construction planes in separate 2D views as is typically done in 3D modeling software. Three primary construction planes displayed in pink, green and blue. Clicking on any of the planes, or the relevant tabs on the top left corner, makes it the active drawing plane. (b) Arbitrary surfaces can also be defined and used as construction planes. Curve drawing. (a) Pen down. (b) Pen moves to define the drawing vector. (c) Dragging drawing vector creates curve with smoothness defined by length of drawing vector. (d-e) Pen up ends curve at start point of drawing vector.
