Awesome! I installed Structures and now I can record and run scripts. 

But, there is an issue with Insert a feature to the mesh. For example, I insert Inflation, I can see it is recorded in the script. But when I run the script, everything in the main Mesh setting is effective, but the Inflation is not created. the error message I get is: 

Script Executed This property is read-only.:line #

where # is the last line.

Thank you in advance. Is there any tutorial on this topic?
