Hello all!
I’m newbie on dynamo and sorry for my bad english. I have a questtion about my box girder project. i create box girder in my family and use dynamo. When i check on dynamo, i get the result volume like this
but when i load it into my project i get the different result volume like this
I’ve been following this forum and seen many solved. I have me too
Hi @Hendri.wicaksono,
You could use the Convert Between Units
node to get cubic meters from the Solid.Volume:

I’m guessing your current result is cubic millimeters.
Afterwards I would create a new volume shared parameter, and then write your new result into this.
Hi @MartinSpence ,
Thanks for your respon and your advice
. I’ve added that node on my box girder dynamo, but still have the same result on my dynamo project like this picture.
Direct shapes do not have a volume as they are not solids by default, so if you need that parameter you’ll have to create the geometry in a different way (ie: FamilyType.ByGeometry and FamilyInstance.ByPoint)
Hi @jacob.small ,
Thanks for your advice and i think this is the solution
. But i still do not have the same result volume like this picture
and i got bigger size box girder than i want from new family, like this
do you have any suggestioin for this problem? 
Okay thanks a lot @jacob.small
