This paper presents an algorithm for imprinting and merging adjacent parts. Imprint and merge is often used to facilitate
generation of conformal meshes between adjacent parts. The algorithm tolerantly intersects the discretized boundary edges of
adjacent faces to calculate the imprint Boolean. An input tolerance is used during the process to minimize the effect imprinting
has on the meshing process. The topology changes from the imprint are generated using virtual geometry so that tolerant
topology can be used. Several examples demonstrate how the present approach may be utilized to improve the mesh quality of
conformal meshes over multiple parts. The approach is shown to work robustly with misaligned and poorly defined parts.
