The inability of a person to draw from memory or from a model, or to construct simple or complex shapes with matchsticks or building blocks: "A person with constructional apraxia usually can't accomplish certain activities that involve building, assembling, and drawing."

"For those who have a mild form of constructional apraxia only the ability to draw in perspective (appearance of objects to the observer) may be lost while the capacity to make gestures and to recognize geometric symbols can be remembered."
