Aspects of the present disclosure include apparatus, method, and computer readable medium for identifying a first geometric position of a first point in space and one or more second geometric positions of one or more respective second points in space associated with placement of the first tool member and a second tool member of a measurement tool, generating a final dimension of a part of the real-world structure based on at least the one or more second geometric positions according to relative geometric relationship with respect to the first point, and displaying a virtual schematic diagram of the real-world structure having the final dimension.
