The present disclosure is directed to a software tool that facilitates the presentation of a three-dimensional view of a construction project as well as the generation of various types of two-dimensional technical drawings based on this three-dimensional view. In one implementation, the software tool causes a computing device to engage in the following operations. The computing device may receive a user input identifying at least one first mesh and at least one second mesh, determine portions of each identified mesh that intersect with a two-dimensional plane, and generate a two-dimensional drawing including a display of relevant dimensioning information based on the determined portions.

An example computing system is configured to (i) receive a request to generate a cross-sectional view of a three-dimensional drawing file, where the cross-sectional view is based on a location of a cross-section line within the three-dimensional drawing file and includes an intersection of two meshes within the three-dimensional drawing file; (ii) generate the cross-sectional view of the three-dimensional drawing file; (iii) add, to the generated cross-sectional view, dimensioning information involving at least one of the two meshes; (iv) generate one or more controls for adjusting a location of the cross-section line within the three-dimensional drawing file; and (v) based on an input indicating a selection of the one or more controls, adjust the location of the cross-section line within the three-dimensional drawing file, update the cross-sectional view based on the adjusted location of the cross-section line, and update the dimensioning information to correspond to the updated cross-sectional view.

Electromagnetic logging tools are optimized using synthetic logs for the purpose of pre-job planning and accuracy/resolution estimation. One, two and three-dimensional forward modeling are used to generate accurate inspection tool responses. A radial one-dimensional (R1D) electromagnetic forward model is also used to compute an approximate log. By constructing non-linear mapping functions between the R1D model-based log and the 2D model-based log, and mapping the R1D synthetic log using the non-linear mapping functions, a quasi 2D log is computed. The quasi 2D log is processed using model-based inversion, thereby providing estimates of pipe parameters. By analyzing the estimates of pipe parameters, tool performance metrics are obtained and analyze to determine the performance of the tool. The tool parameters are adjusted in order to optimize the performance metrics.

Systems and methods include a method for locating a leak in a pipeline. Pressure and flowrate measurements are received corresponding to fluid flowing through a pipeline for which a leak is to be located in a pipeline segment. A calculated leak size is determined based pressure and flowrate measurements for upstream and downstream locations. A first assumed leak location is identified. A first assumed leak size is determined. A simulation is executed based on the first assumed leak size, first assumed leak location, and pressure and flowrate measurements, producing a virtually measured leak size. If a difference between the virtually measured and calculated leak size is not within acceptance criteria, a second assumed leak size is iteratively determined, the simulation is re-executed, and the difference is re-determined. A second assumed leak location is iteratively identified, and the simulation is re-executed to determine an estimated leak location of the leak.
