 Where 20% is placed you could also place anything else, For example 800x800 or just 800x then it will keep the aspect ratio.

+For this project I take a lot of pictures and I don't wanna convert them one by one so i use this command to convert them all at the same time. Warning: It overwrites the files so make backups.

 ## Rules for uploading images to git
 Use jpg's instead of png. Jpg's are compressed and way smaller. Try to keep images under 200 kilobytes.

+# Designing the drone
+
+
+## Drawing the drone
+
+I have a few concept images above and this is the result my drawings.
+![alt text](../../assets/assets_week_2/fusion360/IMG_7688.jpg)
+![alt text](../../assets/assets_week_2/fusion360/IMG_7686-min.jpg)
+![alt text](../../assets/assets_week_2/fusion360/IMG_7712-min.jpg)
+![alt text](../../assets/assets_week_2/fusion360/IMG_7711-min.jpg)
+
+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 third image.
+
+## Designing the drone
+When designing 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 automatically scales when I change one parameter.
+
+## Fusion
+I've had a little bit of experience in fusion. Mostly with making basic cases. But now I wanna learn how to design everything perfectly parametric so if I need to change a length everything will scale with it without me needing to fix some things  
+
+### Previous experience with Fusion360
+I've had some expierence using fusion with my university for making cases in projects. but it was never explicitly thought to me.
+
+
+### Designing parametrically
+Designing parametrically is very hard because every constraint needs to be perfect. Otherwise when changing lengths the design will fold into itself like this.
+![alt text](../../assets/assets_week_2/fusion360/image.jpg)
+
+
+#### What is parametric design?
+Parametric design is the practice of using variables in your cad software, so if you wanna change something. Other parts of the design scale with it. It is very handy if you wanna make last minute changes to your design so you don't have to redo the entire design.
+
+### Offset planes
+Offset planes are something completely new for me. After the lecture I finally knew what they where and how to use them.
+
+#### What are offset planes?
+Offset planes are a way to tell fusion where you want something to happen. For example the splice tool needs a plane to cut through. For that is a offset plane required. For example I wanna cut this design in half. 
+
+### Using the the offset planes
+
+For simplicity im gonna start using the normal Offset Plane.
+![alt text](../../assets/assets_week_2/fusion360/image-14.jpg)
+
+Once that's selected you can select a face to create the offset from.
+
+![alt text](../../assets/assets_week_2/fusion360/image-15.jpg)
+
+![alt text](../../assets/assets_week_2/fusion360/image-16.jpg)
+
+Now we can press split body and select the body and use the offset as a tool to split along to.
+
+![alt text](../../assets/assets_week_2/fusion360/image-17.jpg)
+
+
+The offset planes can be used for almost everything in fusion. You can reference sketches from them and many other stuff.
+
+### Constraints
+There are a few different constraints. When placing things Fusion360 often makes constraints by itself. But additional constraints are needed when making designs parametric. 
+![alt text](../../assets/assets_week_2/fusion360/image-1.jpg)
+![alt text](../../assets/assets_week_2/fusion360/image-2.jpg)
+
+You know when something is fully constrained is when all the blue lines turn black. Sometimes you don't wanna constrain some parts of the sketch because they need to move freely when changing a parameter. For example:
+![alt text](../../assets/assets_week_2/fusion360/image-3.jpg)
+![alt text](../../assets/assets_week_2/fusion360/image-4.jpg)
+
+In the first image in fusion 360 you can see what happens when I over constrained it. It didn't scale well with the rest of the design. I solved this issue by removing all existing constraints and     from the ground up using the basic shape.
+
+![alt text](../../assets/assets_week_2/fusion360/image-5.jpg)
+
+#### Center constraint
+I started off centering the bottom of the design to the center point. I did that by using the Midpoint constraint. Then clicking the origin point and the bottom line. 
+![alt text](../../assets/assets_week_2/fusion360/image-6.jpg) 
+
+#### Lock constraint
+Then I locked the bottom line so it can't change rotation or go down when scaling the sketch. When using the lock/unlock constraint the line will turn green and then you know that line is locked in place. 
+
+
+#### Equal constraint
+After that I made both sides of the line equal because the drone always needs to be symmetrical and otherwise you get off angles and that doesn't look nice. 
+![alt text](../../assets/assets_week_2/fusion360/image-7.jpg)
+
+
+#### Perpendicular constraint
+After that I added a line from Top to bottom and added a perpendicular constraint to both sides so the sketch would always push up and down straight. Once I've made sure both the top and bottom parts of the line.
+
+![alt text](../../assets/assets_week_2/fusion360/image-8.jpg)
+
+#### Sketch Dimensions
+Sketch dimensions are one of the most important things to use. They tell a line how long it needs to be and it makes sure it can't be any other length. I want the bottom and top of my sketch to always be a certain value. For the sides it doesn't matter because if the top and bottom are defined the rest can be calculated if everything is constrained right. I also want the height to work parametrically so that's why I added a center line with a dimensions.
+
+![alt text](../../assets/assets_week_2/fusion360/image-9.jpg)
+
+### Extruding
+After making all the sketches it's finally time to extrude. To extrude you first need to click a face. What is a face? A face is the light blue part of a sketch or it can be a part of a body.
+
+![alt text](../../assets/assets_week_2/fusion360/image-10.jpg)
+
+When you've selected a face you can press `E` and then you can extrude. A new menu will pop up with all the details of the operation.
+
+![alt text](../../assets/assets_week_2/fusion360/image-11.jpg)
+
+In the menu you will find what type of operation you wanna do, You can join the extrude, create a new body from it, intersect or remove part of a body using extrude. You can also specify the length and how you wanna extrude.
+
+
+
+### Adding in components
+I wanted a digital reference on how the drone would look so I have looked for online components so I wouldn't have to make them myself.
+
+I first searched for `Brushless motor 3d design` and instantly found a model on grabcad and downloaded it. After downloading it I imported it into fusion360 using the import button in the top left of the project menu.
+![alt text](../../assets/assets_week_2/fusion360/image-12.jpg)
+
+
+After importing it I dragged it into my design and positioned it in the right location.
+
+![alt text](../../assets/assets_week_2/fusion360/image-13.jpg)
+
+### Result
+After some time modeling this is my result.
+
+![alt text](../../assets/assets_week_2/fusion360/image-18.jpg)
+
+
+## Onshape
+Onshape is completely new for me. I've heard engineering youtubers talk about it and promote it but I've never used it myself. That's also why I took some interest in it. So im going to start off with a [tutorial](https://www.youtube.com/watch?v=2utLjjkXpIg).
+
+The first thing im gonna say off the bat is that I like the parameter menu of Onshape way more than fusion. In Onshape it's on the side instead of a new window that you can't use while sketching or modeling like in fusion. The thing that I don't like is that the camera rotates around the center point of the project and that you can't move it freely like in fusion.
+
+### Sketching
+Another thing thats different from fusion is that you can't instantly give lines variables. You first need to define a length before being able to put in a variable.
+
+I first created the same sketch as in fusion so I could loft the sketches together. ![alt text](../../assets/assets_week_2/Onshape/image.jpg)
+
+The top sketch was made using a offset plane first and then defining the sketch on top of that.
+
+![alt text](../../assets/assets_week_2/Onshape/image-2.jpg)
+
+You can draw lines by pressing the button with the red arrow and set the dimensions using the button with the green arrow. It feels very similar to fusion360
+
+### Extruding
+With Onshape I noticed there are more extrude options available.
+You can choose through how much walls it should go or you can define the dimensions yourself.
+
+To connect the 2 sketches I used loft.
+![alt text](../../assets/assets_week_2/Onshape/image-4.jpg)
+
+What loft does is create a smooth solid surface between 2 surfaces.
+
+![alt text](../../assets/assets_week_2/Onshape/image-1.jpg)
+After that I created a sketch on the front surface with a offset so I could extrude the inside 
+
+![alt text](../../assets/assets_week_2/Onshape/image-3.jpg)
+After that I sketched the motor arms and sketched holes on top to cut the holes.
+
+### 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.
