We have programmatically created various Revit elements using the Revit .NET Creation APIs, specifically those New or Create methods. In this post, let’s create a non-leaning Pisa Tower using all those Revit .NET Creation APIs that have been demonstrated in detail separately and C#.
Here is how the resultant Pisa Tower that we are going to create programmatically looks like first when rendered in Revit.
It is so cool, isn’t it?
Here we go for the whole nice and succint source code.
