Emphasis is placed on the depiction of constructional and architectural relationships. Meccano and Erector remain very versatile constructional mediums. As the study of constructional apraxia impairments narrows, research is concentrating on analyzing drawing abilities. The aesthetic and constructional design of the bridges was also heavily criticised. Erector remains a very versatile constructional medium. Motor imagery has been explored as a potential therapy for constructional apraxia patients. Alzheimer's disease patients with constructional apraxia have unique symptoms. Disconnectors can be classified into various types based upon their constructional features and mounting arrangement. The cartography of India begins with early charts for navigation and constructional plans for buildings. These are known as the relationship continuity constructional units (RCCUs). Nearby uneroded constructional forms are exhibited by most domes. Due to constructional limitations, the Betamovie has no playback function. This model is designed based on the special conditions of constructional projects. These had been given greater constructional strength and a wider beam to support heavier guns. They assisted him with the constructional work, computer simulations, and wind tunnel tests.
