# Lecture notes Wednesday
## Notes regional
Parametic 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 consraints force someting to a length
* imaprative design (click and drag)
* generative design (describe how you want something and it generatis it)
#### Freecad
Different snaps to snap to grid of verticices or edges
#### loft
2 lines on different planes that get connected by loft.
#### Parametric design
Use of spreadsheet
### Intergrate 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
#### Assigment
* 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 descroption with the design files to the class page
#### Next week
* next week paramemtric press fit construction kit.
* focus on constrains and parametric
## Regional Day 2
12 uur blender
2 uur fusion
daarna ffmpeg imagemagick
