DOCUMENT 1

https://bit.ly/3zaudHe write this on the board.

• Getting it setup using https://onshape4frc.com/getting-started

• Going through the tabs

• Parts and Assembly Tabs

• Each Subsystem (climber, swerve, intake) Gets it own Document

• To make sure that the Robot doesn’t get too cluttered, but you can organize the way you want.

• Assemblies - different parts form an assembly (wheel, axles).

• Parts - where you model all of your individual parts, show up in the bottom left

• **Parts Studio - interrelated parts can be modeled in the same environment (studio), (Dumb things that don't move might be in one parts studio)

• Documents can be broken up into different part studios.

• Feature Tree - Every action you take is in the feature tree, shows the history of all of the changes you’ve made, above the parts,

• Everything is moveable and customisable.

• Tab features, bottom left; Tab manager to the left of the plus

• Version History, under the onshape logo, branch and merge designs, high level feature tree

• We need to be able to move around, Cube to change the view, Press the drop down for more options

• Mouse Controls

• Scroll in, zoom in and out, zooms were the pointer is

• Clicking and holding the middle mouse button you can move around one dimensionally

• Double middle mouse click to reset to the center

• Right mouse button you can orbit the part

• Apply to both parts and assemblies.

• If you are really used to using solidworks or fusion go to your account, preferences, and pick the mouse settings 

DOCUMENT 2

• Creating a Sketch

• Outline of our model in 2D, we use it to make something 3D

• Origin is the central point and what we base the model off of.

• Press sketch, leave the dialog box up in the corner, If you see a dialog box that's highlighted, if you click on something on the screen it will get put into the box.

• If you want to do what the dialog box says leave it open

• You can toggle visibility on the planes in the feature tree.

• Toolbar has a bunch of shapes, you will most likely use a lot of these

• Pressing it activates the tool, if you press escape it will get you out of the tool, after you’re done using a tool PRESS ESCAPE, so you don't get lost in a random tool.

• DONT CLICK AND DRAG. its two clicks

• If you need a specific measurement just type it in.

• If you click, and click again it selects both and doesn't get rid of the first

• To deselect, click on the white space, or use the spacebar

• Window Select, click and drag

• Left to right - box is blue, only selects things completely inside the box 

• Right to left - box is yellow, selects everything it touches

• If you’re not interacting with a shape the lines are blue

• You can scale by clicking the corners but you can add Constraints

• Constraints - are geometric rules that you can impose on a model and they have to follow then (hover over points and you can see parallel and perpendicular

• Blue things are unconstrained

• WHEN YOU ARE DONE WITH A PART EVERYTHING SHOULD BE CONSTRAINED

• If you make a rectangle in accordance with the origin it will add a constraint with the origin.

• Black means constrained

• If you make a rectangle starting on the origin (yellow square) coincident constraint, a corner point is attached to the origin.

• First thing you do in a sketch is constrain something to the origin

• So it doesn't change everything.

• Dimension tool, Constraint - just put it on the screen in a way that looks nice

• You can type in measurements in different units.

• You can dimension between two lines, 

• Extrude

• After the dialog box is open select a region, a closed in area (our rectangle),  (highlighted blue), make sure its on solid, 4 inches width

• Add another rectangle on the front side using sketch tool

• Dimension each side .25 inches from the sides

• Extrude this rectangle, (anybody know what the two tabs do?)

• Add tab adds to the original part (so a new part is not created in the parts list)

• New tab creates a new part (a new part is created in the list)

• Remove tab deletes a part of the shape (creates a hole)

• Up to part, up to vertex instead of blind, or through all, mess around with them.

• Merge Scope tells onshape what part to make changes to, if you add multiple parts it will remove from multiple parts.

• Add 1 inch

• Ask them to create a part two inches long above the original rectangle with a gap of .5 inches, on the front face (draw it on the board if necessary), then extrude it two inches perpendicular to the original

• Show off the Feature tree, right click and edit certain parts in history to make changes

• Make a circle on a side of the gray rectangle and dimension WHILE making the circle, if it's in a gray box it's waiting for some sort of input.

• Ask them to make this shape →

• Finish the sketch and it should creates a hole
