SpaceDesign Custom Report Rows
(Ignore the $ signs - the currency signs, and decimal point symbol are determined by your Windows settings)
The Total row was added by the report. The VAT and Total Cost rows were added by the ruby script, based on the calculated total cost.
SpaceDesign Custom Report Rows
By adding some ruby code to your report definition, you can perform calculations based on totals and add additional rows to the report.

Calculations
See the Default Ruby Code below for examples.
Total Values
You can set a ruby variable equal to a value on the totals row, using the name of the column. (not the description). e.g.:
total_cost = total_row["extended_cost"] # replace "extended_cost" with the name of your extended_cost column
To make sure that it is treated as a floating point value, add: .to_f (this helps if you have misspelled the column name.)
total_cost = total_cost.to_f # make sure this has a value if nil
Calculated values
You can calculate new values, based on the total values:
vat = total_cost * 0.175
Formatting values
You can use the ruby command sprintf(sformat, value) to format numbers, e.g. (to display a value with 2 decimal places)
svalue = sprintf("%.2f", vat) # format to two decimal places
There is also a command to add currency symbols and international formatting for decimal points:
svalue2 = dll_call_format_currency(svalue) # add currency formatting
Adding report rows
You add a report row by giving it a description, ( passed to start_custom_row() ), and by setting values in the columns you want to set.
The basic format for this is:
custom_row = start_custom_row("Description")
custom_row["extended_cost"] = svalue
add_custom_row
A similar format can be used to add divider rows:
custom_row = start_custom_row("----------") # start a new custom row with dashes in the description line
custom_row["extended_cost"] = "----------" # add a divider line in extended_cost column
add_custom_row
More Help
if you add trace commands to the ruby code, they will display on the ruby console when the report is generated. This can be very helpful while debugging:
trace("TOTAL COST: %s", total_cost)
trace("VAT: %s", svalue2) # display on ruby console

Modifying the Ruby Script
The custom cuby script is saved in your SketchUp model. If you want to make changes to it, you can save a copy on disk, edit it, and reload it into the model.
- Save or edit ruby data - after clicking this button, the location of the saved ruby data (in a .txt file), will be displayed and you can edit it in a ASCII editor.
- Load edited Ruby data - after editing the ruby script, you need to reload it and save it back into the model.
- Reset to default ruby data - This resets the ruby script saved in the SketchUp model to the default Default Ruby Code.
Errors in the ruby script
Here I have made an intentional error in the ruby script.
In the line after getting the total cost, I have calculated a salesman's commission, but misspelled commission on the next line when calculating the new_total.
#get total_cost
total_cost = total_row["extended_cost"] # replace "extended_cost" with the name of your extended_cost column
total_cost = total_cost.to_f # make sure this has a value if nil
trace("TOTAL COST: %s", total_cost)
#there is an error in the second line below
commission = total_cost * 0.25
new_total = total_cost + comision # misspelled
Error messages
When running the report, I get an error message like this:
Note: that the line number is displayed in the error to help you find it and fix it.
Ruby Console
Also, if you open the Ruby Console, before starting you report, the traces (e.g. :
trace("TOTAL COST: %s", total_cost)
will be displayed and the error message will be reported on the ruby console.
Here is some of the ruby console output for this script:
ADD CUSTOM ROWS TOTAL COST: 0.0 ERROR during add_custom_rows: undefined local variable or method `comision' for #<SpaceDesign:0x95a0e70> CUSTOM ROWS:36:in `add_custom_rows' AFTER ADD CUSTOM ROWS
(The phrases ADD CUSTOM ROWS and AFTER ADD CUSTOM ROWS are displayed before and after your script is called.)
