The Undergraduate Common Entrance Examination for Design is used to determine admission to the Bachelor of Design (B. Des) programmes at IIT Bombay, IIT Guwahati, and IIITDM Jabalpur (UCEED). The subject matter of the course is industrial design, which encompasses a variety of skills such as product design, automotive design, user interface design, etc. It has nothing to do with architecture, and you might search for another exam like NATA for that (National Aptitude Test for Architecture)
NATA is a single testing programme designed to administer aptitude tests and make it easier for prospective students nationwide to apply for admission to architecture programmes at institutions located all over the nation. The test evaluates abilities relevant to a certain subject of study, such as architecture, such as sketching and observational skills, sense of proportion, aesthetic sensitivity, and critical thinking.
The JEE Main Paper 2 is another option, and it offers admission to NITs (alone) for the B.Arch programme.
