E Block Onshape Lessons

Lesson 1

In this lesson, you will:

Update all of your log in credentials.
Link your Google Drive to Onshape to make exporting your work more organised and efficient.
Ensure your preferences are set to MM and not Inches.

You will go on to model a simple desk tidy in order to understand/learn the following.

Refresh/Learn how to Sketch 2D objects and use the Extrude feature to create a 3D shape.
Learn how to use 'Constraints' when sketching and understand how this makes modifying sketches much more efficient and accurate.
Learn the difference between Extrude (Add) and Extrude (New), and when to use them in your modelling.
Learn how and why we sometimes use Extrude (Surface).
Use Extrude (Remove) to remove material.

Lesson 2

In this lesson, you will:

learn how to use the 'Sweep' feature.
understand why it is important to name your sketches and features.
rename the sketches you create for the sweep to be called 'Profile' and 'Path'.
appreciate that the path / profile shapes do have limitations and can prevent the sweep from working.
get more confident to Edit Sketches and Edit Features when things go wrong and change the many variables to try and solve the problem.
remember how to be efficient when sketching by using the 'D' , 'L' and 'N' keys on the keyboard for Dimension, Line and Normalise.
edit the appearance of the parts you create by changing their colour and opacity.

Lesson 3

In this lesson, you will learn how to:

upload an image into Onshape onto a Sketch.
start sketching from an uploaded image.
ensure the size/scale of your image is correct.
use the 'Revolve' feature.
use the 'Shell' feature.
use the 'Section View'

Lesson 4

In this lesson, you will demonstrate your understanding of the three previous lessons by modelling a robot. By doing this you will:

create new parts by sketching and using the Extrude, Revolve and Sweep features, making sure to force Onshape to make the different parts of the Robot 'New' Parts.

Initially, you will draw the basic features of the robot; head, body, legs and arms.

Lesson 5

In this lesson you will:

learn how to create an assembly of your robot and add 'mate connectors' so that your robot can move like a real robot toy would be able to when being played with by a child.

You will be shown how to:

import a 'Part' at a time or your whole 'Part Studio'.
add 'Mate Connectors' to connect the different Parts together.
add Mate Connectors manually or automatically.
set limitations on the movement so that, for example, the head only rotates 45 degrees right and left.

Lesson 6

In this lesson you will use Extrude, Revolve, Sweep and Shell to personalise the robot by adding additional features such as:

Control panel
Hat
Feet
Body details
Face
Any other accessories.

Lesson 7

In this lesson, we are going to look at 'Planes'. You are presented with Top, Front and Right 'Planes' when you begin modelling but it possible to create 'Planes' of your own so that you can sketch and model more creatively and accurately. The options we will focus on are:

Mid Plane
Offset Plane
Line / Angle Plane

Plane - Offset

Here you can see that:

the Plane tool has been selected
the setting 'offset' has been selected
the left surface of the cube has been selected

The new Plane will be created 25mm offset off this surface.

Plane - offset

After creating the new Plane, a square has been skectched on it and then extruded.

plane - mid plane

After crating the new smaller cube, a new Plane is needed exactly in the centre (front to back). To do this:

a new Plane is selected
the option is changed to 'mid plane'
the front and back surfaces of the cube are selected

The new Plane is created exactly half way between the front and back surfaces.

plane - mid plane

This is a different view showing you where the Plane is in relation to the front and back of the cube.

Plane - line/angle

I needed a cylindrical form to come off the top of the cube at 45 degrees. I have no Planes at 45 degrees that I can sketch on. Consequently, I needed to:

click on the create a new plane icon
select the top edge of my cube
change the setting to 'Line/Angle'
enter the degrees or drag the arrow.

You now have a new plane at 45 degrees to the top corner of the cube.

Plane - line/angle

I created a new Sketch on my new Plane. I drew a circle on my sketch and then extruded it. In order to get the cylinder to connect perfectly to the top of the cube, I used the 'Up to next' option. See the settings in the image above.

Lesson 8

You are going to model a range of real life objects. The purpose of this activity is for you to problem solve/work out how you could model them; what Sketches would you draw, and on what Plane? Will you make it 3D by Extruding or Sweepiing? We will do the first one together so that you fully appreciate that everything you model in Onshape can usually be modelled in many different ways to create the same outcome.

Now that you have done these activities and modelled these objects, you have most of the skills you need to model your Single Shot Coffee Pod Machine.
