“…Furthermore, the use of sketching allows to postpone detailing as it inherits a considerate level of abstraction (Leon and Laing, 2013). The creation of model sketches in this workflow is covered by a 4D semantic sketching application named MR.Sketch (Kovács et al, 2022). It sits at the centre of a novel design and integration platform that pursues a bidirectional data exchange for real time feedback and design optimization of sketches.…”

The preliminary development of highly detailed BIM models lacks eligible design methods in the conceptual design stage. Initial design solutions cannot be shared among collaborative and consecutive design parties without relying on error-prone briefings and data exchanges. As advances in Artificial Intelligence are increasingly being used for BIM's big data challenges, this paper presents a workflow based on a small scope of IFC definitions for the generation of conceptual BIM models from 4D semantic sketches, using a machine learning based pipeline. The workflow offers a user-friendly architectural design perspective, while preserving information more reliably throughout the entire life cycle of a BIM model.

“…Strokes2Surface is built upon a 4D sketching interface named MR.Sketch [KEKF23], targeted for architectural design, utilizing a tablet (iPad) and a stylus (Apple Pencil) as its primary drawing medium. The interface enables the creation of 4D sketches by employing 3D canvases, where the 2D strokes drawn on the tablet's surface are projected onto the canvases, forming 3D strokes.…”

“…To this end, building upon MR.Sketch , a pen‐on‐tablet 4D sketching interface targeted for architectural design developed within our research group [KEKF23], we introduce the Strokes2Surface geometry reconstruction pipeline. Strokes2Surface processes 4D architectural design sketches to form well‐connected curve networks, thereby bridging the gap between the concept design and digital modeling stages.…”

We present Strokes2Surface, an offline geometry reconstruction pipeline that recovers well‐connected curve networks from imprecise 4D sketches to bridge concept design and digital modeling stages in architectural design. The input to our pipeline consists of 3D strokes' polyline vertices and their timestamps as the 4th dimension, along with additional metadata recorded throughout sketching. Inspired by architectural sketching practices, our pipeline combines a classifier and two clustering models to achieve its goal. First, with a set of extracted hand‐engineered features from the sketch, the classifier recognizes the type of individual strokes between those depicting boundaries (Shape strokes) and those depicting enclosed areas (Scribble strokes). Next, the two clustering models parse strokes of each type into distinct groups, each representing an individual edge or face of the intended architectural object. Curve networks are then formed through topology recovery of consolidated Shape clusters and surfaced using Scribble clusters guiding the cycle discovery. Our evaluation is threefold: We confirm the usability of the Strokes2Surface pipeline in architectural design use cases via a user study, we validate our choice of features via statistical analysis and ablation studies on our collected dataset, and we compare our outputs against a range of reconstructions computed using alternative methods.

Advanced computational design tools can help architectural and product designers to create novel and innovative designs. In this paper, we describe how advanced tools from research projects may be used together to design, simulate, and fabricate transformable luminaires. These tools support rapid design and simulation iterations to converge towards a realizable, usable and aesthetically design, which negotiates real-world constraints such as production costs, manufacturing time and material properties. We report on our experiences with integrated design and production workflows from teaching a digital design and production class, asking students to design and produce a luminaire based on a given production infrastructure. The design process starts with a conceptual part, where design intentions and basic ideas are explored with a 3D sketching tool. Students then develop parametric models by determining independent and dependent design parameters. As a required feature, the luminaire should have a transformable screen designed by a generator for flexible quad-surfaces. Real-time rendering tools allow for a fast, visual evaluation of these designs. After selecting the most suitable design regarding the design intention, students evaluate production feasibility and iteratively update their design until all production constraints are fulfilled. We describe the didactic and technical concepts and conclude with a discussion of open issues.
