Lecture
This lecture delves into the geometry of frames, focusing on the perception of beam widths within structures, the construction of 2D sketches on a reference plane, and the implications of angled cuts on beam widths. By examining the discrepancies between perceived and actual beam widths, the instructor demonstrates the importance of geometric accuracy in frame design. Through detailed sketches and explanations, the lecture highlights the significance of precise geometric considerations in ensuring structural integrity and uniformity in frame construction.
