In this paper, we present some sketching interactions for 3D modeling, based on a set of two different bidimensional sketches (profile curve and silhouette curve). By using these two sketches and combining them with a gesture grammar, a very large variety of shapes (including shapes with topological holes) can be easily produced by our interactive modeling environment.
With SketchUp, a 3D modeling program, you can take your architectural and material design ideas from your head to your screen. In this course, instructor Scott Onstott shows you how to use the free version of SketchUp to explore possible design scenarios using photos and 3D models.
Learning Sketch-based 3D Modelling from user’s sketching gestures Hugo Lopez-Tovar University College London Gabriel J. Brostow University College London ABSTRACT To infer three-dimensional models from two-dimensional sketches, most of the existent research focuses on image sim-ilarity, requiring a minimum of drawing skills, which is often.
To create a 3D model in SketchUp, you’re constantly switching among the drawing tools, views, components, and organizational tools. In this article, you find several examples that illustrate ways you can use these tools together to model a specific shape or object. The examples illustrate a few of the different applications for creating 3D models in SketchUp: woodworking, modeling parts or.
Simply put, Natural Sketch provides a more intuitive way to create geometry than the 3D Sketch tool does. Sketching has always been important to design. The closer 3D sketching tools come to imitating a pen and paper interaction, the better they become at serving their core purpose, creating and expressing an idea in the most efficient manner possible.
Good designers and engineers know how to explore and iterate their designs. Thankfully, computer aided design (CAD) allows you to do just that—explore and iterate your design—until the model suits your needs. However, this iteration process isn’t as easy as it sounds. It requires you to move quickly and seamlessly back and forth from 2D sketching to 3D modeling—and so, that’s.

The extracted features are used for sketch-based shape retrieval. Comparative results obtained from six other well known methods within the literature have been discussed. Using MPEG-7 contour shape database (CE-1) as the test bed, the new proposed method shows significant improvement in retrieval performance for sketch-based shape retrieval.
