2025-10-13 3DM Practical (CP#3 Floors+Roofs+Railing+Stairs)

Quick recap

The meeting focused on addressing submission issues and progress updates for a project involving 2D CAD work and checkpoints, with discussions about missing submissions and ongoing work on windows and other elements. Brian demonstrated various design and modeling techniques in Revit, including creating and modifying buildings, beam systems, and roof structures, while emphasizing the importance of understanding the software's tools for efficient model creation. The team discussed upcoming deadlines and presentations, with Brian reminding students about the importance of completing Checkpoint 3 before the holiday and encouraging them to customize their designs using Revit's features.

Next steps

• All students to complete Checkpoint 3 before October 25th.

• All students to finish the upper floor and roof by the end of today's class.

• All students to complete railings and stairs during the week when there is no class.

• Groups 9 and 10 to present their topics on October 27th instead of next week due to the holiday.

• Brian to post the class recording for students to reference while completing their models.

Summary

Checkpoint Submissions and Progress Review

The meeting focused on addressing submission issues and progress updates for a project involving 2D CAD work and checkpoints. Evelin raised concerns about missing submissions for Checkpoint 1 and 2, which Brian agreed to investigate by checking the grades system. Evelin also mentioned difficulties with the windows in the current checkpoint, which Brian confirmed was still due later.

Revit Progress and Checkpoint Deadlines

Brian discussed the current progress of the class with Revit, noting that students' capabilities with the software are not yet at the level of their ideas. He mentioned upcoming class activities and the transition to BIM in the next semester, which will focus more on drawing production rather than modeling. Brian expressed concern about the low submission rate for the checkpoint, which is worth 50% of the grade, and reminded students about the upcoming holiday and the deadline for Checkpoint 3. He suggested completing Checkpoint 3 before the interim crit on the 28th to alleviate any potential burden.

Building Design Window Placement Discussion

The team discussed design modifications for a small building project, focusing on window and door placement. Brian explained how to properly cut openings in walls and join wall elements in their modeling software, addressing issues raised by Ansel and Evelin about window placement and wall cutting. Brian demonstrated the use of the "join" tool and explained how to mirror cuts from one wall to another, simplifying the process of creating openings in both the front and back walls. The team was encouraged to make adjustments to their designs as needed, with Brian confirming that simplified designs were acceptable.

Rivet Modeling Techniques Overview

Brian explained that the current module focuses on modeling using Rivet, emphasizing the difference from traditional CAD where modeling skills are essential. He demonstrated how to create a building design with an overhang, upper floor, deck, and shed roof using various tools like edit profile and wall openings. Brian advised students to prioritize using door openings or wall openings for cuts, and to use edit profile only when necessary, as it can be less flexible for moving walls.

Beam System Design Demonstration

Brian demonstrated how to create a beam system for a floor structure in their design software. He explained the concept of using major floor joists and summarizing the 3D model into only the main elements, rather than modeling every individual timber member. Brian showed how to use the beam system tool to create a framework for the second floor, setting the workplane at the top of the floor joists and sketching the beam layout. He also demonstrated how to easily modify the beam system by trimming and adjusting the layout, including creating a space for future stairs.

Building Model Design Software Demo

Brian Williams demonstrated how to create and modify a building model in a design software, focusing on adding a floor slab, adjusting beam systems, and constructing walls and a roof. He explained the process of copying and aligning elements, setting levels, and editing sketches to match his initial design intentions. Brian also highlighted the importance of understanding the software's tools and options to efficiently create and refine the model.

Rivet Roof Design Demonstration

Brian demonstrated how to create and modify a roof in Rivet, explaining the process of defining slopes, adjusting angles, and adding structural members. He showed how to use reference planes to attach walls to the roof at an angle and discussed the options for copying and adjusting structural members. The demonstration included practical examples of modifying the roof thickness and adding beams to match the slope of the roof.

Revit Beam System Design Demonstration

Brian demonstrated how to create and modify beam systems in Revit, focusing on roof construction and structural support. He showed techniques for copying, editing, and aligning beams to reference planes, while emphasizing that timber roofs must include proper structural elements like roof joists and rafters. The session concluded with Brian explaining that the next steps would involve adding stairs, railings, and interior walls to complete the design.

Revit Project Progress Update

The team discussed the progress and next steps for their project in Revit. Brian instructed the group to complete the upper floor and roof by the end of the week, as they would not have a class next week. They worked on adding stairs and railings to the model, with Brian demonstrating how to use various tools in Revit to create different types of stairs and railings. The team also learned how to modify and customize stairs to fit their design needs. Brian encouraged the group to use the provided recording to work on their assignments independently.

Revit Railing Profile Customization

Brian Williams demonstrated how to customize railings in Revit by editing the profile of a top rail to match a desired design. He showed how to create a new profile family type with dimensions 50x100mm, and then load it into the project to replace the default 50x50mm profile. The process involved using the family editor to modify existing profiles and create new types, with Brian explaining the parametric nature of these changes.

Revit Railing Customization Demonstration

The instructor demonstrated how to customize railing types in Revit by creating and editing families, including changing baluster sizes and profiles. He showed how to modify top rail offsets and add wire rails to create a detailed railing system. The instructor emphasized that students could use default railings if preferred, but encouraged them to push the boundaries of Revit's features for higher scores. He announced that checkpoint 3, the complete model, would be due in two weeks, and reminded students to finish the roof and upper floor before the next class. He also mentioned that groups 9 and 10 would present on the 27th, while groups 7 and 8 would present the following Monday.
