Abstract: A computational geometry server is provided that includes a server, a communication link, at least one client, and an interrupt interface. The server has processing circuitry and an operation manager. The operation manager is configured to compare source geometric data in a source geometric model with target geometric data in a target geometric model. Furthermore, the operation manager is operative to identify discrepancies in the geometric data between the source geometric data and the target geometric data. The at least one client communicates with the server over the communication link. The interrupt interface is operative to notify a user of the presence of an inability to automatically generate an accurate representation of the source geometric model in the target geometric model. A method is also provided.

Abstract: A geometric model comparator is provided, which includes processing circuitry, memory, and comparison circuitry. The processing circuitry is configured to generate a target model from a source model. The memory is configured to store the source model and the target model. The comparison circuitry is configured to identify selected points from the source model, create corresponding selected points in a target model, and compare the selected points from the source model with the selected points from the target model to identify one or more selected points from the target model that fall outside of a predetermined tolerance range with the respective one or more points from the source model. A method is also provided.

Abstract: A staircase assembly comprising a plurality of stringers, and; a plurality of stair units, having treads and risers wherein stair unit is secured by means of fastening means on each corner to said plurality of stringers, said stringers, having a diagonally shaped series of equally spaced substantially vertical structure notched out of one side to define the length and height of each step of the stair assembly. The said tread,-forming a channel by rolling the leading edge for holding the riser of the stair unit installed immediately below, and each stair unit is secured by means of fastening means on each corner to said plurality of stringers, said channels further engaging other stair unit laterally sliding for providing horizontal adjustability.
