# Boolean and Rounded Corners

• I have a code that generates a pattern of single rectangles according to a text input.

``````def letter_a():

fill(0,0,0)
rect (2*x,2*y, rectWidth, rectHeight)
rect (3*x,2*y, rectWidth, rectHeight)
rect (4*x,1*y, rectWidth, rectHeight)

return letterWidth

def letter_b():
fill(0,0,0)
rect (2*x,2*y, rectWidth, rectHeight)
rect (3*x,2*y, rectWidth, rectHeight)
rect (3*x,1*y, rectWidth, rectHeight)

return letterWidth

#etc.

def drawLetter(func):
with savedState():
rotate(letterTilt, center=(letterWidth/2, 200))
width = func()
translate(width, 0)

textInput = "abcd\nefgh"

save()
for char in textInput:
if char == "\n":
restore()
translate(0, -y*2)
save()
else:
func = characterMap.get(char, draw_notdef)
drawLetter(func)

saveImage("~/Desktop/Cyborg-Alphabet.svg")

``````

This is the pattern it produces:

I would like to 'stylise' the resulting pattern, with the equivalent of a Pathfinder in Illustrator and a rounded corner effect so it looks like that:

Is there a way to do this in Drawbot?

• he Lara!

Nice to see you continuing your drawBots!!

``````x, y = 300, 300
s = 100
# draw your rects as ovals
oval(x, y, s, s)
oval(x + s, y, s, s)
oval(x + s, y + s, s, s)
# build up connections with rects
rect(x + s/2, y, s, s)
rect(x + s, y + s/2, s, s)
``````
