Generating two-dimensional views for two-dimensional clash detection

A non-transitory computer-readable medium, wherein the non-transitory computer-readable medium is provisioned with program instructions that, when executed by at least one processor, cause a computing platform to:

• receive, from an end-user device associated with a user, an indication of a request to generate a two-dimensional (2D) cross-sectional view of a three-dimensional (3D) model of a construction project;
• generate the requested 2D cross-sectional view of the 3D model by:
• tracing respective intersections of (i) a cross-section plane with (ii) respective 3D meshes representing two or more objects in the 3D model;
• and
• based on tracing the respective intersections, determining a respective 2D object boundary for each of the two or more objects;
• receive an indication of user input defining at least two object classes for which to detect clashes between objects of the 3D model that are represented within the 2D cross-sectional view;
• based on the user input:
• identify, from the objects of the 3D model that are represented within the 2D cross-sectional view, a set of objects that are within the at least two object classes;
• and
• evaluate whether there are any intersections between respective 2D object boundaries of objects in the identified set of objects and thereby determine that there is an intersection between (i) a first 2D object boundary of a first object of the 3D model that is in the identified set of objects and (ii) a second 2D object boundary of a second object of the 3D model that is in the identified set of objects;
• based on the determined intersection between (i) the first 2D object boundary of the first object and (ii) the second 2D object boundary of the second object, identify a clash between the first object and the second object of the 3D model;
• and
• cause the end-user device to display a respective indication of the identified clash.

A method carried out by a computing platform, the method comprising:

• receiving, by the computing platform, from an end-user device associated with a user, an indication of a request to generate a two-dimensional (2D) cross-sectional view of a three-dimensional (3D) model of a construction project;
• generating, by the computing platform, the requested 2D cross-sectional view of the 3D model by:
• tracing respective intersections of (i) a cross-section plane with (ii) respective 3D meshes representing two or more objects in the 3D model;
• and
• based on tracing the respective intersections, determining a respective 2D object boundary for each of the two or more objects;
• receiving, by the computing platform, an indication of user input defining at least two object classes for which to detect clashes between objects of the 3D model that are represented within the 2D cross-sectional view;
• based on the user input:
• identifying, by the computing platform, from the objects of the 3D model that are represented within the 2D cross-sectional view, a set of objects that are within the at least two object classes;

• based on the determined intersection between (i) the first 2D object boundary of the first object and (ii) the second 2D object boundary of the second object, identifying, by the computing platform, a clash between the first object and the second object of the 3D model;
• and
• causing, by the computing platform, the end-user device to display a respective indication of the identified clash.
