Abstract: A modular layout form has a substantially planar rear for attachment to a support structure, and a substantially planar front having a two-dimensional array of receptacles for holding objects to be embedded in a settable material (e.g., concrete) in a predetermined pattern with staggered courses. The form has substantially straight lateral edges, which results in a pattern of incomplete receptacles along the lateral edges. Object-retention members (e.g., clips, tabs or elastomeric rims) extend into the receptacles for securing objects in the receptacles. Adjacent forms can be combined by abutting their lateral edges with their incomplete receptacles aligned to create completed receptacles. Objects are then inserted into the completed receptacles to engage the object-retention members and hold the adjacent forms together.

Abstract: A modular layout form has a substantially planar rear for attachment to a support structure, and a substantially planar front having a two-dimensional array of receptacles for holding objects to be embedded in a predetermined pattern in a settable material (e.g., concrete). The form includes a plurality of courses staggered with respect to one another to define a pattern of recesses and protrusions at the ends of the courses. Sets of tabs and slots on the recesses and protrusions can be used to engage complementary tabs and slots on the recesses and protrusions of an adjacent form, so that a plurality of forms can be combined by sliding adjacent forms together laterally in a common plane.
