Initial Setup: Before we start, please ensure that your grid settings are as follows:

• Major Grid spacing: 100mm

• Minor Subdivisions: 10

(This will make every small square 10 mm x 10 mm)

To change these at any time, you can go to the 'Grids and Snaps' tool on the bottom toolbar, then 'Grid Settings'.

From where the red and green lines cross, draw a vertical line that extends 80mm (8 squares).

Again, identify the intersection of the red and green lines, then draw a rectangle that is 10 mm high (1 square) and 20 mm wide (2 squares).

Step 3: In the top toolbar, select the FIT POINT SPLINE tool. 

Starting from the top-right corner of the rectangle you drew in Step 2, create a lightbulb shape that connects to the top of the vertical line drawn in Step 1.

The FIT POINT SPLINE tool will create a line that follows wherever you click. Press ENTER to complete the shape.

Note: It does not matter if your shape is perfect, as this can be adjusted in the next step.
