In short, use this add-in to:
Now, replace the word “wall” in the sentences above with: floor, roof, ceiling, pad or structural foundation slab.
Creation of Revit® family instances with Python code in Dynamo is easy to do if you have the right code snippet. So I am sharing it here.
Code snippet shows how to do few useful tasks:
It is important to know that Revit® does not support all Revit® categories when creating Multi-Categories Schedule or Material Takeoffs.
Not knowing that may lead to omissions and wrong quantities.

Revit Beams are also known as “Structural Framing”.
Typical arhictectural (floor) plan view shows particular level with it’s cut plane set approximately 120cm from the level. Also, beams from the level above are shown in floor plans. And, here comes our first problem with Revit: what’s the easiest way to show our beams without too much manual interaction?
There are several solutions for showing beams “from above” in Revit floor plan views, each of them having their pros and cons: Read More
In your Revit project documentation, sometimes you want to display parameters or values that are not available in Tag’s Label dialog.
Let’s take an example:
Door fire rating is a system parameter that you can use (and tag) with a door family. But, you do not want to display parameter value but rather a symbol representing value (or a range). There is no way that Revit will allow this to happen using regular Tags, that is, Tag familiy cannot “read” a value and then “decide” what graphic symbol to use. You must do this manually by using “correct” tag or tag type.
There is, however, an alternative solution. It is not coolest solution because it is off Revit’s logic (where model elements and annotations are separated) but it works.
What you need to do is: Read More
In Revit we have two types of lines: model lines and annotation lines. In short, model lines can be modelled in any kind of view (plan, section, 3D etc.), and they will be visible in 3D (and in other views), hence the name “Model lines”. Annotation lines depend on a view they are drawn in, and they are visible only in that particular view (of course, they can be copied to other views as well), hence the name “Annotation lines”. Both, model and annotiation lines are members of the Revit category called Lines.
Line appearance is defined in the Line Styles tool. Each line style is a unique subcategory of the Revit Lines category. Managing lines in Revit is quite easy, using Object Styles tool or Visibility/Graphic Overrides tool we can turn lines on/off and change their appearance.
Line Styles tool can be run from the ribbon, choose Manage tab, then Additional Settings, and finally, option

In general, Revit lines are made out of three elements (parameters):
When we talk about “lines”, we mean Revit lines in general: e.g. drawing lines, and lines (edges) of Revit’s objects (edges and other lines in Revit family instances), which we can see in plan views, sections and Revit other views.
Color of the line is self explanatory. Now, let’s talk some more on the Revit Line Patterns.
In Revit, line patterns can be adjusted in the project (or template) file. Revit has it’s line patterns adjusted directly in the Read More
