Quick recap

The instructor addressed technical matters and clarified submission requirements for 3D modeling assignments while updating the class schedule with upcoming checkpoints. The class engaged in hands-on activities focused on creating and modifying models using Revit's family editor, including demonstrations on creating benches, working with reference planes, and modeling terrain features. The session concluded with instructions on loading and placing trees in the design project, along with submission deadlines for various class activities.

Next steps

• All students to submit the bench model by the end of the day.

• All students who haven't submitted the foundation from last week to submit both the terrain and foundation by the end of the day.

• All students to submit Checkpoint 2 by Wednesday, October 1st.

• Brian to update the Class Activity 2 link on the website to reflect the new agreement.

• Brian to update the group list on the website to include Tarick in Group 9 and Daniella Webby in Group 7.

• Brian to send Davina her sketch file.

• Groups 3 and 4 to present their topics later today.

• Tarick to communicate with his group members about the presentation requirements.

Summary

Zoom Issues and Assignment Updates

Brian addressed technical issues with Zoom and reminded students to check their grades and profile settings. He clarified an error in the submission form for 3D modeling assignments and instructed students to resubmit their work using the correct form. Brian updated the class schedule, noting that students would complete Checkpoint 2 in class on the 29th and move on to Checkpoint 3 the following week. He also mentioned introducing the family editor and having students build and submit a terrain model.

Rivet Project Checkpoint 2 Preparation

The class discussed the progress of their Rivet project, focusing on the upcoming submission of Checkpoint 2 by Wednesday, October 1st. Brian explained the importance of the family editor in Revit for creating and modifying objects, emphasizing its role in ensuring objects are compatible with Revit's functionalities. He guided the class through a class activity where they modeled a simple bench using the family editor, highlighting the differences between creating objects in Revit versus importing them from other software. Brian also mentioned the availability of pre-made Revit families online for future reference.

Revit Bench Modeling Class

Brian led a class on creating a bench model in Revit, focusing on using the family editor for custom modeling. He demonstrated how to create reference lines, extrude boxes for the legs, and work with different view planes. The class learned about workplanes, which determine the direction of extrusions, and how to use tools like Align and Trim/Extend. Brian emphasized the importance of understanding planes and reference planes in Revit for family modeling. The session concluded with instructions on saving the family file, distinguishing between RFA and RVT files.

Work Plane Techniques in Revit

The instructor explained the importance of choosing the correct work plane when creating extrusions in Revit, emphasizing that the direction should be considered for future modifications. He demonstrated how to set and adjust work planes, and discussed the benefits of using reference planes for organizing and aligning objects. The lesson concluded with a practical exercise on centering and evenly spacing objects in a model, using the dimension tool to adjust distances and create equal spacing.

Revit Grouped Elements Demonstration

Brian demonstrated how to create and distribute grouped elements in Revit, focusing on using reference planes and dimensions to ensure consistent placement. He addressed issues raised by Davina and Jenalee about the movement of reference lines during dimensioning, promising to investigate further after class. Brian then guided the group through loading their bench models into the project, correcting some placement errors along the way.

Revit Families and Terrain Modeling

The class learned how to create and modify families in Revit, with Brian demonstrating the process of creating a bench family and explaining how to load and edit components. The students then practiced creating a terrain model by drawing contour lines based on specified elevations, with Brian guiding them through the process of using the Toposolid tool and setting up the base level at the waterline. The class also discussed techniques for selecting multiple elements and Brian provided tips for working with the family editor.

Terrain Modeling and Design Techniques

Brian demonstrated how to modify terrain in a design software, including changing its thickness and adding points. He showed how to create a water body by modeling a custom shape. Jenalee encountered some technical difficulties but Brian helped her resolve them. They discussed the concept of a cut plane and its relevance to construction drawings. The session concluded with plans to add trees to the design.

Water Feature Modelling Demonstration

The instructor demonstrated how to create a water feature in a model using Modelling Place, explaining the process of selecting generic models and adjusting parameters. Students encountered some technical difficulties with materials and finishes, which the instructor helped resolve by explaining the need to edit objects in place. The instructor also showed how to import and place trees in the model, selecting from various palm tree families.

Foliage Design and Submission Guidelines

The instructor, Brian, provided guidance on loading and placing trees in a design project, explaining how to use different tree plugins and create 3D views. He announced that students must submit their terrain and foundation models by today to earn points for Class Activity 2, and the bench design for Class Activity 3. Brian also addressed questions about group assignments and clarified submission requirements for various class activities.
