How to create a section of bridge beam

Good morning,
I would like to create a bridge beam. I have drawn 4 sections in Sketchup and would like to create them with loft tool (or other).
Initially I created the “wire Source” node by selecting the 4 sections in right sequence.
I followed the organ bench tour but… i’m lost.
Can you give me some suggestions?


Can you please upload here your Sketchup file so we can take a look?

Of course!

Hi Massimiliano, thanks for the file. Unfortunately what you are trying to do is not possible with the current version of Viz, because your profile has holes. We’ll look into adding that functionality in the future
