List total values from Schedules in Revit

Hi everyone,

I’m a freshman in Dynamo. I need your help to reduce my freshness :).

I’m in trouble with Schedule in Revit. I have a lot of schedules to calculate the value of: Site Coverage, Garden Area, Site Permeability with both in Area and Percentage.

Now I want to create a list of that total calculate Parameters, somethings like below:

SITE AREA_____________: X m2 (Get from Project Parameter on Area + Project Information)
SITE COVERAGE_______: X1 m2_________Y1% (Total value from Site coverage Schedule)
SITE PERMEABILITY____: X2 m2_________Y2% (Total value from Site Permeability Schedule)
GARDEN AREA________: X3 m2_________Y3% (Total value from Garden Area Schedule)

Could you please show me the right way to do?

Many thanks,

Thanks for your guidelines. I’m working on that. Still struggle but have some small steps.

I started to create on Dynamo like the image.
I can export the value from Site Area (Project Parameter) to Excel file
but how could I get the total value of other Calculate Parameter (Site Coverage, Site Permeability, Garden Area)

Thanks in advance,

@daotangluc You can create a list of all parameters like this:

Thank you so much,

I discover another issue, SITE AREA is Project Information, but the others are Areas

So I change the codes, but the new issue is how could I get the total value of one Calculate Parameter?


This could help ?

Thank you so much.
Now, I can get the value from schedule, but I can’t summarize the value with SUM
Which is my mistake?


Use a Object.Type node and check your data. Math.Sum can just add integers/doubles

I check, but the object type is null.

What happened with the values?




@salvatoredragotta: thanks for your help,

So I succeeded to export to excel as image.

But now, how could I import that excel to drafting view/Legend?

Or could I put the values to Text parameter and show in another schedule?

@daotangluc Glad you to hear!. Please mark this topic as solved and start a new topic for your new issue.
