Abstract: An embodiment of a method of positioning features in a digital design space includes receiving a request from a user to place a first feature in the design space, and based on the request, placing the first feature in the design space, and coupling a first positioning handle to the first feature in the design space. The first positioning handle is graphically represented in the design space and manipulatable by the user, the first positioning handle has a fixed position and fixed orientation relative to the first feature, and the first positioning handle includes a first face surface and defines a first vector. The method also includes moving the first feature into a pre-determined position and orientation relative to a target feature in the design space by mating the first positioning handle to a target positioning handle coupled to the target feature.

Abstract: A computer-aided design method for a building comprises the step of receiving, by a processor, an object to be placed in a grid that represents at least a subset of a building, the grid including a macro grid and a micro grid. The type of the object is determined by the processor. Based at least in part on determining that the type of the object is shell, the processor provides a user with the macro grid for placing the object, otherwise the processor provides the user with the micro grid for placing the object. A segment size of grid lines displayed in the macro grid is larger than the segment size of the grid lines displayed in the micro grid. The object is placed in a location in the grid based at least in part on instructions received from the user, and the grid is displayed to the user.

Abstract: Disclosed is a method for preparing a floor comprising the steps of preparing one or more floor structures comprising an upper surface arranged in parallel to a lower surface; and one or more channels disposed vertically between the upper and lower surfaces and longitudinally extending along the upper and lower surfaces, each of the one or more channels having a top and a bottom; preparing a foundation; attaching a sill plate to the foundation; placing one or more floor structures on top of the rimboard and attaching the floor structure to the sill plate and foundation.
