A method, in each of three orthogonal orientations, obtains dimensional layers of triangular mesh data of the 3D object from a slicer program. Perimeter length values for each layer of each of the three orthogonal orientations are obtained and compared to stored perimeter length value for a reference object to determine a degree of matching. Measurement data is facilitated by processing by CNC/3D print software. Smaller objects within the 3D object are also analyzed. For a more robust approach, each triangle in the triangular mesh data is analyzed by totaling the perimeter of surrounding triangles to assign a value. Matching with the reference object is made based on the assigned total perimeter values. The 3D object can be scaled in one, two or three orthogonal dimensions to match the reference object.

A data distribution program causes a server apparatus to execute a process of distributing project data to a terminal apparatus that writes the project data to a device among a plurality of devices included in an apparatus. The data distribution program causes the server apparatus to execute: receiving a distribution request for the project data from the terminal apparatus; identifying a related device that is another device constituting one apparatus together with the device to which the project data designated in the distribution request is written; identifying the related device that requires update of project data based on a version of the project data designated in the distribution request and a version of the project data written in the related device; and transmitting, to the terminal apparatus, the project data designated in the distribution request and the project data to be written to the related device identified.

In one embodiment, a modeling process adds unique numbers for field welds or flange bolt-up connections to a virtual construction model of an infrastructure construction project. Based on the virtual construction model and a fabrication data file that describes a portion of the infrastructure construction project, a QC drawing generation process generates a QC drawing for the portion of the infrastructure construction project that includes balloons linked to locations of field welds or flange bolt-up connections, each balloon including the unique number of a corresponding field weld or flange bolt-up connection. A copy of the QC drawing is provided to a field inspection worker. Subsequently, a marked-up copy of the QC drawing is received back that includes field inspection results associated with the unique number of each field weld or flange bolt-up connection. The marked-up copy may be maintained in a document control system.
