Multiple frameworks to visually depict detailed processes with ease.

Automatic drawing with Plus Create. Intuitively suggest relevant shapes based on what you are visualizing on the canvas.

Connect items with dynamic connectors (lines, curves, arrows) that stay connected and arrange themselves as you make changes.

What is a Block Diagram?

Block diagrams are high-level flowcharts used to design new systems or to describe and improve existing ones. It has a specialized structure that provides a high-level overview of major system components, key process participants, and important working relationships.

How to Create a Block Diagram?

  • Begin by opening a Creately workspace, you can make edits to multiple pre-made templates or start creating your block diagram from scratch.
  • Identify all the components, inputs, and outputs within your system.
  • Use the purpose built shape library and simply drag-and-drop symbols and notations onto your canvas. Use the Plus Create feature to easily connect shapes with arrows to indicate the flow of data.
  • Identify and label your inputs and outputs- this refers to the starting points of a process and the resultant action that occurs along the way.
  • Invite collaborators and design effective systems in real-time with Creately’s advanced collaboration features.
