Week 7


This week: TRUSSES


End of video #1: I appreciated the pace of this video in comparison to the one last week. I followed the first video with no problem. Here’s the outcome of video #1. Some of the commands used to get this outcome include: number slider, reverse, move, and divide. Note: It is best to align label your number sliders as soon as you make them, it makes it a lot less confusing in the end.


With the points command, I got a little confused as to what was showing up on my screen and what was happening in the video. As you can see above, the video only has the “P,S” input, while my input has “P,T,L,S”, and I have no idea what would go into the T and L input if I was doing this one my own. But in the end, I figured out hat to make the truss, I can just ignore it and move on.


FINAL PRODUCT 1.0: TADA, what a beautiful looking truss. I really appreciate how versatile this truss can be with all its variations. The possibilities are endless.


FINAL PRODUCT 2.0: The catenary truss was a lot simpler than I thought it would be. Hooray for 7-minute videos. It is interesting how adding a few commands can greatly alter the output.

Step 1 and Step 2 Mishap: The moment I moved the curve to be the input for the divide command instead of top cord, this line jumble occurred. For a good 5 minutes I tried troubleshooting, and was on the verge of giving up and going home for the day since I did what was required already. BUT THEN…


TADA: But then I remembered that we could switch the numbering, which controls the alignment. It is highlighted above, but you can see that I had to switch around the inputs for the bottom cord to make it work.


FINAL PRODUCT 3.0: Here is the curved truss, it all its glory.

Reflection: Grasshopper still makes me feel like a firefighter with the connecting hoses. When following the video, it seems pretty straightforward and simple. But I know that if I were to do this on my own, I would have no clue how to move past step 1 and have a usable outcome. I feel that over time, this will all make sense eventually. But as of now, baby steps.
