Setting up a new question formula
Within a question formula, operations are performed according
to the rules of algebraic logic. Use parentheses to set off separate operations
within a formula.
Before you begin
If you have not already opened the Model window and selected
the model you want to work with, do so now.
To set up a new formula:
- With your cursor in
any line in the model, enter =, right-click,
and then click Save as Q Formula.
- Click [Add].
- In the Formula field, enter a brief name for the question
formula. You can use
and
for this purpose.
- Select ,
,
or other question formulas from the Calculation Elements list to build
a calculation in the .
- In addition to
the functions available for regular formulas in Estimating, there are
other functions developed specifically for working with question formulas
in Model Estimating. To see a list of these functions, click here.
- When you finish setting
up the calculation, click [OK]
to save it as a question formula.
- Test the formula to
make sure it works properly. How?
Tips:
- You can type
directly into any field in the model or in the formula bar. To save the
formula for use throughout the model, right-click, and then click Save as Q
Formula.
- After you set up your question
formulas, you can print the Model Database report from the menu to check them. (In the Model Database Report Options window,
Report Options tab, select Print Question Formulas.)
- You can use question formulas
to include or excludes lines in your model during takeoff. How?
