What is Onshape?
What is Onshape?
Onshape is a 3D CAD software (CAD stands for Computer Aided Design). Onshape is really easy to use and there are lots of tools to make it easier to shape your design. The bad thing about Onshape is that it does not allow copy and paste. Onshape is used for mechanical CAD in many industries, including consumer electronics, medical devices, and 3D printing. But we will be using Onshape just for 3D printing instead and also so that we can see the big picture of our new design in 3D

Name your document 'Your name's' Lamp Project or 'Your form' 'Your name's' Resin Poured Lamp.
Make sure your document is owned by you and then you can select 'Create public document' (the blue button below) and now you can make a visual 3D design of your model in there.
Sharing
Select the share button on the top right corner after you've created your document. Go to 'Indivisuals' and add in your teacher's email so that they can see and help you with your work. Make sure that you choose the 'Can Edit'
3D designing tools
3D designing tools
Main tools we (might) are going to be using are:
Sketch tool
Allows us to draw on different planes.
Extrude
Used to create parts or surfaces.
Mirror
Replicates parts, surfaces, faces, or features across a mirror plane.
Fillet
Rounds sharp interior and exterior edges
Revolve
Creates a solid body by revolving a selected profile or model geometry around an axis in Fusion.
Line
Allows you to create single lines or line segments within a sketch.
Spline
Allows you to draw smooth, curved lines by creating a series of control points that define the shape of the curve.
Trim
Allows you to remove portions of sketch entities or curves, or trim frame segments, by intersecting them with other entities or faces.
Dimensions
allows you to define and measure distances, angles, and other geometric properties within sketches and drawings
Process
Process
Use the sketch tool to make a new sketch.
Select the plane you will be drawing on (most likely front)
First I drew a singular straight line using the line tool (cheat code, press 'l' on your keyboard and it'll select the line tool for you!) and then used the dimensions tool (cheat code, 'd' !) to measure out the base of my model
I drew out the rest of my base (shape) using both the line tool and the spline tool. Because my design had a lot of curved lines (design) it was a bit difficult so I had to draw a lot of lines within the base (shape) its self. When doing this the dimensions tools is very important as it can help with measuring the height and width of shapes as you can see on the right hand side.
Extrude part cuz I forgot (note to self, delete this later)
For the next part I used the face blend tool to make a smoother connection between the two curves (and also because if I don't do this, making a fillet edge on the wood won't work). I selected the two faces (top and bottom curves) and changed the radius to 5mm.
Above the Face blend tool is the Fillet tool. Select the Fillet tool and the edges of your base. This will add a sanded-edges look to the base.
After I finished drawing my base I drew out my neck design the exact same way I did with my base using the different tools provided.
The next step is to extrude the neck, following the same steps I did for my base. Then I used the boolean tool which allows my neck to do through my base (by cutting a part in the base).
Attempt one: Extruding the rectangular surface of the neck's base. There is still a small part left as you can see. ✖
Attempt two: Drawing a larger box on a new sketch in the same position and then extruding it. ✔
On the sketch I drew my lamp's neck design on, I drew an extra line across in the position I want my 'rings' to be in.
Plane tool: Used for creating a new plane on your desired position.
Select on the line you've drawn, set the plane's setting to line angle and then change the angle to 90 degrees.
On a new sketch select your new plane and use the 'center point circle' tool to select the middle of your circle and then adjust the size of your shape.
Repeat the same process for the inner circle.
Extrude your 'ring' as a new part and then repeat this same process for the smaller ring.
On a new sketch I drew out a rectangle with the correct measurements on how large I want my lamp's head to be using the dimensions tool.
I used the transform tool to tilt my lamp's head's down a little following my originaol design.
I selected on the rectangle and then used the colored tool (blue) to slightly adjust the rectangle.
And just like the rest of the designs, I drew them out using the various tools (line, spline, sketch fillet, dimensions) then extruded it.
Creating a drawing
Creating a drawing
On the bottom left corner of your screen, select the plus sign and create a new drawing.
Create a custom template and make sure to change your settings to match with the example ⬆
On your new drawing insert a drawing of your whole model (highlighted on the right side). Change the view scale to 1:3 and repeat this but in different angle (view orientation).
Hover your mouse over your workspace and click to paste the drawing.
Do the same but for different angles

On a new sketch I drew out my resin design and used the extrude tool to remove that shape from my base (merge scope - base).
Next I drew the top view of the resin design and then removed it from the base too.
The problem at the moment is that there's a part that was removed that shouldn't have been. So what I did was trace over the part that I wanted it to reappear and then extruded it upwards from the base of the model (make sure it's not extruded as a new separate part).
But to create the drawing from the base I needed to make a new plane from the bottom of the base using the same steps as before, then I was able to trace the part I needed.
The next step is to extrude the resin part and as a new piece then cut out the excess part using the split tool.
Select the line you want to use to split the resin piece into two separate parts, as shown in the photo as an example.
Extrude your selected line as a new surface going over the resin block.
Once you've made a new surface, use the split tool, select the block of resin and your extruded surface. Lastly hide the part that isn't needed.
The next step is to extrude the side of your resin but don't make a new part, instead use the add tool so that it is identified as the same/a connected piece (resin).
The final step is to use the split tool and the same steps as shown before to add details to your resin design (The resin shouldn't go through wood so the excess parts should be cut out).
For my lamp's neck I needed to split them into three separate parts for me to be able to put wires and a battery inside the neck so that the lamp will function. So I started off by making a new sketch on the right plane, using the line tool to draw/ mark out the lines I want to use for splitting the neck (either 3, 5, or 7 parts). Use the dimensions tool to help you divide the space between each lines evenly.
Repeating the same steps before splitting your design, extrude your selected lines as new surfaces (make sure it is long enough and goes through the whole design). →→ With the split tool once again, split your lamp's neck into the several parts according to the number of your extruded surfaces.
You only need to work on the middle section of the neck so you can hide the other two parts. On the middle piece, draw out a small space for the battery and a pathway for the wire to travel though the neck. Link the space for the battery to the outside and the (lamp's) head. Do this on a new sketch (face of the surface you are working on) do not work on the front plane (provided). Then remove your drawing from the middle piece using the extrude tool.
Results are as shown on the right. Finally you can bring back the other parts of your lamp's neck and then your design is complete (lamp neck).
Use the shell tool to hollow the inside of your lamp's head. (Do this step before splitting the lamp's head into two and after you're sure you've finished designing the shape of the lamp).
Draw a line horizontally across your lamp's head, the line should be drawn on the same height as the top of your lamp's neck. Extrude a new surface making sure the surface covers the whole model, as shown. Then use the split tool to cut the head piece into two.
Your lamp's head needs to be able to be attached to the neck somehow so in this step you are going to draw a rectangle to cut out a rectangular hole on the space covering your neck piece inside the lamp's head.
Use the extrude tool to remove the drawn part and you should end us with something that looks like this. Once this step is completed then you can 'show' the other part of your lamp's head and then your lamp model is finished (although you still need to create a drawing).
