A computer-implemented method for selecting an edge among edges of a 3D object in a 3D immersive environment of a CAD system. Each edge is oriented in the 3D immersive environment. The method comprises displaying the 3D object in the 3D immersive environment, detecting a hand gesture including all fingers folded except thumb, determining an oriented line formed with the folded fingers of the hand in the 3D immersive environment, and identifying the edge of the 3D object having the closest orientation with the oriented line.

A system for arranging and executing transport of alimentary components. Data is received by at least a server based off one or more diagnostic outputs of biological extractions, performed by a diagnostic engine, and a transport request based on the diagnostic outputs and other data pertaining to the user is transmitted to a client device associated with one or more physical performance entities. Based on the geographic location of the user and the transport request, one or more physical performance entities configured to transmit alimentary components aligning with the transport request are identified, and the transport request is transmitted to the client device based on a determination by the at least a server that the one or more physical performance entities include an ability to execute the transport request.

A system and method for tracing polygons in a drawing source file. The method includes extracting vector imagery from the source file, creating a planar representation of the vector imagery as a plurality of lines, filtering the plurality of lines to create simplified line art, morphologically dilating the simplified line art to generate a polygonal approximation, calculating geometric difference between the source file canvas bounds and the polygonal approximation to identify contracted polygons, morphologically dilating the contracted polygons to create visual polygons, and filtering the visual polygons according to one or more geometric parameters to identify salient polygons.

In an aspect an apparatus for analyzing machinability of a part for manufacture, wherein the apparatus comprises a processor. The processor is configured to receive a representative part model of a part for manufacture. The processor may also be configured to extract a semantic datum from the print of the part for manufacture. A machinability datum is determined as a function of the semantic datum. A manufacturing quote is generated as a function of the machinability datum.

In an example, a method includes obtaining a compensation model characterising a relationship between a location of an object within a fabrication chamber of an additive manufacturing apparatus and a geometrical compensation to be applied to a model of said object, wherein different geometrical compensation values are associated with different locations. In some examples the method further includes determining a magnitude of a dimension parameter of each object of a set of objects to be generated in a build operation. The method may include determining a spatial arrangement of objects to be generated within the build volume, based on the magnitude of the dimension parameters and the geometrical compensation values for an intended location of object generation in the spatial arrangement.

A method for determining parameters of a high-frequency vibrating mill with three grinding drums is disclosed. The mathematic modeling is established by applying the average parameter method and transfer function method; the synchronization-stability capability coefficient curve, and the dimensionless coupling torque maximum value diagram of the system are obtained by the characteristic analysis of synchronization and stability. Finally, the curves of rotational velocity of motors, displacements of mass bodies, and phase difference between exciters are obtained by the simulation, and the correctness of the method is verified by the comparison of characteristic analysis and simulation. The parameters of the high-frequency vibrating mill of the present invention can lower the technical requirements of exciters, reduce the loss of the exciters, increase the service life of the mill.
