Average CAD Service Costs. A typical drafting company will charge $100 to $120 per hour. Architects charge slightly more, averaging around $130 per hour. A typical A0 drawing of one type of a house will take about 8 hours to complete, which would cost between $800 and $1,040.Larger structures, such as a municipal building or an office complex, may take up to 24 hours to complete.rchitects charge slightly more, averaging around $130 per hour.

Proper fraction is one where the numerator or the number on top is less than the denominator or the number at the bottom and the overall value is less than 1.
This gives rise to a new and different kind of number -- a fraction. It is a number we need for measuring rather than counting. We are then able to say that a certain length, for example, is 5Â¼ cm. And so what we call a proper fraction is a number less than 1. Fractions belong to what is continuous rather than what is discrete. See The Evolution of the Real Numbers, Lesson 3. We will see that everything we have learned about ratios will apply to fractions, because, as we will see, each numerator has a ratio to its denominator.
