Original
Change
Unfinished sprocket missing angles and semicircles.
I refined it by finishing the missing shapes using OSNAP and Line tool.
Thermostat
Original Change
It is missing color, organization, and some boxes.
I used grouping to add colors, I used blocks to add the lines and add the circuits in the groups, and I used OSNAP and line tool to add the boxes.
Mountain Bike
I used instructions to step by step build the mountain bike. I used blocks to connect the pieces of the bike together and make it whole.
Optical Illusion
I built the optical illusion from scratch. I created it by using OSNAP to create the outer layer and have each angle have a line going to the middle, then I removed some of the lines to make a cube in the middle.
