What is the harmonious relationship of parts to each other and to the whole

In design, the principle that can be defined as "the harmonious relationship of parts to each other and to the whole" is UNITY. The design principle of UNITY is present when an artwork feels like on piece, rather than disjointed sections. To truly achieve UNITY these parts work together in a way that creates an overall meaning within the artwork. To create UNITY in an artwork consider using one colour palette throughout an artwork or balancing contrasting colours with connecting features such as a simple motif/design that is present throughout the entire work of art.

cad, or computer-aided design and drafting (cadd), is a software for design and technical documentation, which is an automated process as opposed to the manual drawing of plans. this gives a person an advance in making plans as an architect in a short period of time. one who can render plans through this software will gain a skill that is better than one who makes plans manually. this is a skill some companies look for in an employee.
