The freeform architectural modeling process often involves two importantstages: concept design and digital modeling. In the first stage, architectsusually sketch the overall 3D shape and the panel layout on a physical ordigital paper briefly. In the second stage, a digital 3D model is created usingthe sketch as a reference. The digital model needs to incorporate geometricrequirements for its components, such as the planarity of panels due toconsideration of construction costs, which can make the modeling process morechallenging. In this work, we present a novel sketch-based system to bridge theconcept design and digital modeling of freeform roof-like shapes represented asplanar quadrilateral (PQ) meshes. Our system allows the user to sketch thesurface boundary and contour lines under axonometric projection and supportsthe sketching of occluded regions. In addition, the user can sketch featurelines to provide directional guidance to the PQ mesh layout. Given the 2Dsketch input, we propose a deep neural network to infer in real-time theunderlying surface shape along with a dense conjugate direction field, both ofwhich are used to extract the final PQ mesh. To train and validate our network,we generate a large synthetic dataset that mimics architect sketching offreeform quadrilateral patches. The effectiveness and usability of our systemare demonstrated with quantitative and qualitative evaluation as well as userstudies.
