Diagrams

1 / 8

Today I made diagrams for the modules. I used the same view as the isometric renders. I made copies of all of the diagrams with hidden lines, but I only think the cylinder needs them, and not even that badly. The dashed lines appear to be different line weights because of the resolution, so I will need to re-export them to fix it or just use the diagrams without hidden lines.

Next I will be putting together the presentation. I plan on making grids of renders and diagrams, keeping in mind that the presentation will only be viewed from small computer screens, not a larger projected screen. I should also probably do more historical/context research.

Diagram Issue

I thought I should get a head start on diagramming since I realized that I they should probably be completed by the end of Monday at the latest, leaving only today and Monday to work on them. I have two options for the diagrams. I can dimension the models then explode the dimensions so they will transfer when I create the 2d representation, or I can do the dimensions in Illustrator. Either way, I need to use Make2D. The problem is that not all of the lines are complete or lined up in the result. It could have something to do with the workspace tolerances, but I'm not sure.

Renders Batch 2 (Traditional Perspective)

I realized that for the renders, some of the pieces look better in traditional perspective than isometric, which I used for the first batch of renders. I decided to rerender everything in perspective so I have both to chose from, and I will use isometric view for diagrams.

Renders Batch 1 (Isometric)

Today I finished generating structural analysis reports and moved on to renders. I ended up using the solid douglas fir option in Scan and Solve for the wood bases instead of creating a bamboo plywood material.

The rest of my time was spent on creating passable renders for CSW. I know they are not perfect, but they are good enough for my use case. The noise reduction option helped a lot since my previous renders had a lot of noise that I couldn't seem to get rid of. I have the three example configurations for simple modules left to render, then I will move on to getting 2D representations to start diagramming.

Update 4/25: I completed the renders of the three simple module configurations

Structural Analysis Report Work

Today I ran all of the modules and most of the configurations through structural analysis. I generated reports for them, which are posted on the platform as well. I have three configurations left to test because they have bamboo plywood components and Scan and Solve does not have a plywood option by default. I need to create a custom composite material to represent the bamboo before I can run the tests, or I can just say that it is a different solid wood.

Interlocking-20Chair-20Module-201-20Report.zip

I have decided to simplify my designs to three simple modules with wood surrounds (public furniture) and the interlocking modules. The plan is to show the modules themselves and give examples of configurations that can be made with them.

I downloaded Scan and Solve as suggested by Ammar instead of using Karamba since it is a lot simpler. This afternoon, I added material properties for mycelium based on information from different sources on mycelium composites, and I ran tests with the simple and interlocking chair modules. A report generated for the chair module is included for download.

Moving forward I will be setting up parameters for testing the different configurations based on how I expect people to apply weight to them. After structural analysis, I will start rendering and creating diagrams of the modules and configurations.

Mycelium Properties

The mycelium I purchased seems to be available again, and they list some properties on the website. It is possible that the store shutting down had to do with COVID-19, but it is also possible that they just got it running again after transferring the main operation to a different company.

  • Density: 7.6 lbs/ft3
  • Compressive Stress/Strength at 15% compression: 18 psi
  • Flexure Strength: 34 psi

Interlocking Modules In Rhino

Today I recreated my interlocking modules sketched from the weekend in Rhino. I used the same dimensions (17" single seat, 34" double height) as I did for the simple modules, and I matched all of the angles. I tried 60 and 75 degree angles before settling on 65 degrees as the best option. After extruding single and double width modules from the sketches, I tried fitting them together to come up with different configurations.

My next steps are to decide which modules and attachment methods I want to continue with and finalize them. I hope to get started on basic structural analysis by the end of the week. Next week I plan to work on research, diagrams, formatting, and citations for my presentation, but I might be able to extend the designs/analysis into Monday if I absolutely need the extra time.

Grasshopper and Karamba3D Practice

Today I followed some tutorials on Grasshopper basics for when/if I get to doing structural analysis of my designs. I have never used Grasshopper before, but I think I understand the basics now.

I also checked on the example file from Karamba3d, the Grasshopper plugin for structural analysis. I had had trouble with the file earlier since all of the components appeared blank, but today I figured out that I just needed to zoom in farther. I was able to select different beam materials and adjust the load with a preview.

Interlocking Modules and Handles

This afternoon I took some time to sketch out a selection of interlocking shapes and move them around to create different configurations. My intention was to see how well more complex shapes could adapt to form multiple furniture pieces as opposed to the simple shapes that I have been working with. I think it could work to use interlocking shapes, but I would need to test multiple configurations and modify the shapes as I go to be as adaptable as possible.
