Exercise 1 Write a macro to build a spongle

The primitives used are a box, cyl, snout and dish:

The box is 1000 x 1000 x 1000 The cyl is 400 dia x 600 high The snout is 300 high x 600 Dtop x 400

Dbot The dish is 600 dia x 300 high

Note: use connect p-points syntax to connect theprimitives together:

e.g. CONN P1 TO P2 OF PREV

Exercise 4

Convert the basic ladder building macro to aPML2 function

Call the function ex4.pmlfnc

Define the function with 3 arguments:!name, !height and !width

Remember to think carefully about whatdata-types to use for the arguments

To call the function type:

!!ex4(myladder,3000,350)

Exercise 6

Create a call-back method.convertctof() to convert a

temperature in degrees Centigrade toFahrenheit and put the result in the

Fahrenheit gadget. Create a call-back method

.convertftoc() to convert a

temperature in degrees Fahrenheit toCentigrade and put the result in theCentigrade gadget.

The formulae for the conversions are:degf = degc * 1.8 + 32degc = (degf 32) / 1.8

Exercise 7

The temperature range frame onyour form is designed to give youpractice using do loops andwriting methods.

It works by taking a minimum,

maximum temperature and a stepsize. Pressing the apply buttoncauses the complete range oftemperatures and theirconversions to be displayed in theresults table.

Take care to avoid potentialhazards such as no values givenin a field and a maximum valueless than the minimum.
