Therefore, data interoperability does exist between various CAD programs.In this lesson plan, students investigate different types of water bodies on Earth by making models of lakes, oceans, and rivers inside an aluminum pan using various materials and real water. However, the majority of CAD programs do support the ability to read other CAD file formats. Most, if not all, of these programs support their own CAD file format. There are many different types of CAD software programs currently available.
Styles are intended to support objects that share common display attributes (for example, color, font, and line type). In addition to drawing layers, styles provide an additional level of organization for objects. They serve as a subset of a CAD drawing, and their visibility can be controlled by you. Drawing layers are groupings of objects that share similar physical characteristics. CAD drawings employ the use of drawing layers and styles to organize their collection of data. These object types help support a CAD drawing by providing additional information about the document or links to a database. Embedded images, referenced drawings, and nongraphical data (for example, object data, database linkages, and so forth) make up the remaining objects.
For example, a water line may have a piece of text adjacent to it that reports its diameter. Text, labels, and dimensions provide basic attribution of entities. These shapes are defined by their underlying geometry and coordinate locations.
Geometric shapes are used to represent the majority of CAD drawing entities such as lines, points, and polygons. CAD drawings are composed of various objects-some of which are graphical and nongraphical. CAD drawings are a popular format for storing and exchanging vector-based spatial information. Others serve as data collection documents that are used in other systems such as a geographic information system (GIS). Many of them serve as legal documents that define real-world objects or a proposed plan. CAD drawings are typically file based and are used in professional disciplines such as engineering, architecture, surveying, and mapping.
