Topographical survey engineering education retrofitted by computer‐aided 3D‐printing

Abstract

Due to the sophisticated nature of contour lines on 2D drawings, students often find difficulties in visualizing three‐dimensional interpretations of flat and 2D displays, especially when they attempt to comprehend topographic maps. This study aims to determine the issues encountered in topographical survey education that could be mitigated by 3D‐printed models and to explore the effectiveness of hands‐on 3D‐printing exercises in real teaching practices by guiding students to design and fabricate 3D models using 3D‐printing techniques. A mixed method combining quantitative and qualitative approaches has been employed including experiments and structured interview surveys. The qualitative ethnographic method through a qualitative experiment developed 3D‐printed models for topographic education. Topographic maps were developed using Sketchup Version 8 software in order to fabricate the 3D topographic models. Hands‐on 3D‐printing exercises engender better understanding and appreciation of topographic maps among the students. This research demonstrates how 3D models could complement the conventional teaching using 2D maps in university education.

Designing Construction 4.0 Activities for AEC Classrooms

“…Adequate facilities such as laboratories, maker and fabrication spaces and medium-to large size hardware are needed for large sets of students simultaneously. Educational proposals are particularly developed in the realm of additive manufacturing and digital fabrication [9][10][11][12]. In the realm of construction robotics, References [13][14][15] have studied student's cognition and motivation when developing experiences in AEC classrooms.…”

Retrofitting ancient timber glulam mortise & tenon construction joints through computer-aided laser cutting

“…The CADspan engine produced STL files that describe the exterior of the CAD files ready for 3D printing. MeshLab was also used for final checking of the 3D models and provided an alternative to export the 3D drawings to STL (.stl) format or OBJ, 3DS, PLY, STL, OFF formats, which was used to remove any duplicated faces, automatic filling holes, and smoothing (Wang et al, 2018). Laser CAD v7.52 was used to transfer the 3D models to the laser cutter because it is compatible with AI, BMP, PLT, DXF, DST formats.…”
