Abstract: A computer-aided design (CAD) system may support spatially-aware detection of trapped support areas in 3D printing. The CAD system may detect trapped support areas in the surface mesh in that detected trapped support area do not have linear access to an opening in the surface mesh, including by surrounding the surface mesh with a virtual bounding box that encloses the surface mesh, mapping the virtual bounding box and surface mesh into a 3D cube space, and tracking mesh cubes and bounding cubes of the 3D cube space. For a given mesh face of the surface mesh, The CAD system may determine whether the given mesh face is part of a trapped support area by projecting a ray from the given mesh face and assessing the given mesh face as part of a trapped support area based on the ray passing through a mesh cube or a bounding cube.

Abstract: A method, computer program product, and system includes a processor(s) obtaining an authorization failure from a target application because an access request was denied based on insufficient permissions of a user. The processor(s) institutes a mock interface with a visual appearance of the target application. The mock interface displays predefined data and the target application displays dynamic data, from the server(s) executing the target application. The processor(s) obtains, via the mock interface, a request to change the permissions of the user to the target application, which includes a selection, by the user, through the mock interface, of one or more individual permissions displayed in the mock interface. The processor(s) automatically generates a customized security policy comprising the selection, where based on applying the customized security policy, repeating the access request results in authorized access to the target application.
