Gliffy is a popular online diagramming tool. For simple diagramming requirements, the following tools should work just fine.
Microsoft Visio is the most popular diagramming software, however, there are alternatives that are often as good and in some cases, free. Shape-based artwork is more commonly used to depict lesser technical information. CAD contains a lot more information such as the materials, processes, and specific conventions of the diagram. Vector shapes are not affected by edits and are the most appropriate to use when precise measurements are required.Ĭomputer diagramming can be shape-based artwork or more complex drafting often seen in CAD (Computer Aided Design) programs. However, vector shapes are mathematical representations of a shape and hence scale well.
Raster shapes or bitmaps do not scale well, and their resolution and quality deteriorates with every edit. Modern computer diagramming relies on using vector-based shapes instead of raster shapes. Diagrams are made of shapes, objects and stencils, which when combined together correctly, can help project a lot of useful information.
