Lecture notes Wednesday¶
Notes regional¶
Parametric design - scalable objects (so that if you change one parameter everything changes with it)
Try as much design softwares as possible
Parametric design is different in every design software
Notes global¶
Constraints¶
equality constraints to make things the same size dimension constraints force something to a length
- imperative design (click and drag)
- generative design (describe how you want something and it generates it)
Freecad¶
Different snaps to snap to grid of vertices or edges
loft¶
2 lines on different planes that get connected by loft.
Parametric design¶
Use of spreadsheet
Integrate 3d view in website¶
https://grabcad.com/
Video encoding¶
Use H.264 to encode videos with
ffmpeg -i input_video -vcodec libx264 -crf 25 -preset medium -vf scale=-2:1080 -acodec libmp3lame -3q:a output_video
Assignment¶
- model a possible final project with cad in 2d and 3d
- make photorealistic render
- make a movie
- make a simulation that it works
- compress them
- post the description with the design files to the class page
Next week¶
- next week parametric press fit construction kit.
- focus on constrains and parametric
