The vector stencils library "Cloud shapes" contains 69 geometric shapes.
Use it to design your cloud computing diagrams and infographics with ConceptDraw PRO software.
"The essence of a diagram can be seen as: ...
- with building blocks such as geometrical shapes connected by lines, arrows, or other visual links." [Diagram. Wikipedia]
The geometric shapes example "Design elements - Cloud shapes" is included in the Cloud Computing Diagrams solution from the Computer and Networks area from ConceptDraw Solution Park.

The vector stencils library "Solid geometry" contains 15 shapes of solid geometric figures.
"In mathematics, solid geometry was the traditional name for the geometry of three-dimensional Euclidean space - for practical purposes the kind of space we live in. It was developed following the development of plane geometry. Stereometry deals with the measurements of volumes of various solid figures including cylinder, circular cone, truncated cone, sphere, and prisms.
The Pythagoreans had dealt with the regular solids, but the pyramid, prism, cone and cylinder were not studied until the Platonists. Eudoxus established their measurement, proving the pyramid and cone to have one-third the volume of a prism and cylinder on the same base and of the same height, and was probably the discoverer of a proof that the volume of a sphere is proportional to the cube of its radius."

The shapes example "Design elements - Solid geometry" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Mathematics solution from the Science and Education area of ConceptDraw Solution Park.

The vector stencils library "Education diagram" contains 20 solid and transparent geometric shapes: rectangle, rounded rectangle, ellipse, cloud, circle, diamond, hexagon, starburst, flag.
Use it to illustrate your education infograms with block diagrams.
"A diagram is a two-dimensional geometric (can be three-dimensional also) symbolic representation of information according to some visualization technique. They have been used since ancient times but became more prevalent during the Enlightenment. Sometimes, the technique uses a three-dimensional visualization which is then projected onto the two-dimensional surface. The word graph is sometimes used as a synonym for diagram." [Diagram.
