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
