Google Sketch 5: Adding shape by using Follow Me

Step 4: the shape is colored in transparent to show that there is a line that the triangle followed to make such shape.

Step 3: The line has to be on the same axis, otherwise, following won't be continuous.

Step 2: Triangle is drawn and the face of triangle is pulled along the line I produced on Step 1 by Follow Me too.

Step 1: Draw lines where you want to use the Follow Me tool.
