Many models start with basic shapes. In SketchUp, the shape tools help you draw rectangles, circles, and polygons. You find these tools on the Getting Started toolbar, the Drawing toolbar, and the Large Tool Set toolbar. Drawing a rectangle or square In SketchUp, you can draw rectangles ...
See Drawing Basic Shapes for more about those tools. Dividing faces When you draw a line (or a curve) on an existing face, you split the face. After you split a face, you can use the Push/Pull tool to push or pull one part of the face while the other part stays put. See ...
Over the past year I've received an influx of requests to create a new practice tool for basic shapes such as cubes, spheres and pyramids, for use in practicing the basics of structure and lighting. I've been conducting some early test photoshoots in service of this goal -I would love ...
We first create the dots using the Point structure. These dots are actually a series of coordinates through which we will draw lines. Figure 9.3 shows a set of six points using the basic Windows coordinate system. To connect the dots, we use the DrawPolygon method of the Graphics class. ...
The Drawing library provides a set of built-in basic shapes for constructing scenes. Getting Started The following example demonstrates the complete implementation for rendering a static scene. In terms of the Drawing API, this scene consists of apath(the border),text, andimage. ...
