Revit Macro: Generate sections and views of beams and columns

This macro creates sections and views of beams and columns.
Macro works with beams in plane and inclined beams.And also with usual and inclined columns.
In current example macro creates one side view to beam/column and 3 cross sections along beam/column. This sections can be used to show rebars in RC structures, for example:
