+# Lecture notes
+
+## 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
