### Parameters
|
||||
The parameter menu is very nice in Onshape It is on the side of the screen and it doesn't close automaticly when modeling. Which is very nice.

|
||||
|
||||
### Other notes
|
||||
I think Onshape is a solid to fusion360 but the part that im missing is that I can instantly assign variables to anything. On another note Onshape is a lot nicer when working parametrically because you can slide the parameter menu on the side next to the design.

##### Issue with adding videos
|
||||
When trying to view videos on the web my firefox says no MIME type.
|
||||

|
||||
|
||||
I fixed it by searching basic video tag documentation. Then I added `type="video/mp4"` to every video tag. Because when pasting in images in markdown vscode forgets to add it.
|
||||
|
||||

|
||||
|
||||
What I also needed to do is set the absolute path instead of the relative path. For some reason it added `Assignment` in the link when trying to load the video
|
||||

|
||||
Its supposed the be `link.org/assets/video` instead of `link.org/assignment/assets`. But for some unknown reason it changes it. The fix now is to set the absolute path starting with `/assets/video.mp4` So now its referenced like this. ```html
|
||||

## Conclusion/My thoughts
|
||||
I liked this week. I learned a lot about blender and OnShape at the start of the week I really hated Onshape because I didn't like how to camera feels and finding all the tools is frustrating but after a while I got comfortable with it and I liked some aspects of it. I also worked with Fusion360 also learned a couple of new things in there like the offset planes.

I wanted to combine 2 random objects that interest me into one project. A drone and a jumbotron. So im gonna make a drone with multiple screens on it that could for example be used for traffic control or entertainment purposes.
|
||||
|
||||
## What does the drone do?
|
||||
The drone needs to be able to fly for atleast 20 minutes. It needs 2 screens on both side so it can display images or video. I wanna program the drone myself so I know how drones work and how they keep themselves upright.

## Drawing the drone

I have a few concept images above and this is the result my drawings.

In the second picture you can see that I wanted to make the drone 30 cm in length. But then I looked at the prices for bigger batteries and it started to get super expansive real fast. So I decided to make it smaller. So now im planning on making a drone 10 cm in length. Im still going for the design in the thirth image.

You can also kinda see that I got my inspiration from the third concept art image. And im giving my on twist on it.

## Designing the drone
|
||||
When desigining the drone I wanted to do everything parametric. So im going to try to use as much variables as possible and make everything depend on each other so everything automaticly scales when I change one parameter.

|
||||
|
||||
## Designing paramemtricly
|
||||
Designing parametricly is very hard because every constraint needs to be perfect. Otherwise when changing lengths the design will fold into itself like this.
|
||||

|
||||
I've spend one day getting the constraints perfect for the sketch so it scales well with everything.

|
||||

|
||||
I've spend one day getting the constraints perfect for the sketch so it scales well with everything. And this is the result of that. When I change one parameter in the variable menu the entire body scales with it. This is the final result of my design. I've made the body myself and I've imported the components from grabcad. So I had more time for blender and Onshape and so I could visualize it better.
|
||||

|
||||
|
||||
### Rendering
|
||||
I've also made a render of the drone to visualize it for other people. Making this was kind of a pain because blender is a gigantic program. You can see my [docs](../Assignments/week_2_computer_aided_design_(cad)/drone_designing.md) to see where I struggled. This is my final result of the render. I've wished it looked nicer but I didn't have enough time to dive deeper into blender.
