This beginner Fusion 360 tutorial takes you step by step through drawing, posing, and rendering a real object – an IKEA IKORNNES mirror.
(To work “backwards” from a finished product is called “Reverse Engineering”)
You will often need to “copy” a physical object back into the digital world:
New designs always need to coexist with other components; hardware, fasteners, electronics, even mobile phones.
(Even if only a box, it helps to have a digital model of what goes inside)
Having those components in your design helps ensure that everything fits and works together.
By following this tutorial, you will;
- Improve your experience and confidence with Fusion 360.
- Learn how to make a design with multiple components and joints.
- Learn some tricks to make using Fusion 360 easier.
- Be inspired to use some of these techniques in your own designs.BIG BIG TIP: If anything goes wrong, Undo will get you out of trouble!
(‘Ctrl+Z’ or ‘Command+Z’)
You can see that the mirror has two main parts, a body and a handle.
If the handle is flat, the overall shape becomes easier to design.
Let’s model the mirror in this way, with it facing forwards.
- Open a new design.
- Click on the ‘Create Sketch’ icon.
- Hover over and click on the plane that faces forward – you should now be in an empty sketch view, with the view cube showing ‘FRONT’.
If you see something else, Undo and try again.
Sketching: Rounded Rectangle
Looking at the mirror again, its basic shape is a rounded rectangle. Lets draw that.
- Inside the sketch, use the rectangle tool (Select from the drop-down menu, or press R), to draw a rough rectangle. Right now the size or shape is not important.
- Select the sketch fillet tool, then click on each of the rectangle corners, then press the Enter key.
Note: Do not stop and try to enter dimensions until all four corners are selected.
- Now that we have the correct basic shape, it’s time to add dimensions and constraints. This makes it the correct size, in the correct place.
Tip: When sketch geometry is fully-defined, it changes from blue to black. This helps you know that you’ve dimensioned and constrained the sketch enough.
Firstly the rectangle needs to be constrained relative to the origin.
Select the bottom of the rectangle, then while holding down the Shift key select the origin point. Both should be highlighted.
In the ‘Sketch Palette’ menu, click on the Midpoint constraint.
- We measured the mirror beforehand: the height is 400 mm, the width is 255 mm, and the corner radius is 35 mm.
Select the dimension tool. (press D to start dimensioning and Esc to stop)
Click the left and right edges, then type in the width.
Click the top and bottom edges, then type in the height.
Double-click the existing radius, and type in the correct radius.
Notice how the sketch changes colour as each dimension is added.
Now that the basic shape is in place, let’s add more detail.
The mirror has an wooden edge that wraps around the mirror, the same thickness the whole way around. The offset tool is a perfect way to draw the inside line.
We measured that the thickness is roughly 10 mm.
- (While still inside the first sketch)
Select the offset tool (press O or find it in the Sketch dropdown menu).
Click on one edge of the round rectangle.
- You can specify the offset amount by dragging the slider, or by entering the exact amount in the text box.
You might find that the value has to be ’10 mm’ or ‘-10 mm’ to look right. It just depends how your rectangle was drawn.
- Click Ok and your inside line has been created!
If you need to change the distance, double-click on the dimension and type in a new value.
