    Dynamo Revit

    I've recently been looking into different ways to speed up my Revit workflow, such as scheduling and using shared parameters. I was told to look into the Revit feature, Dynamo, but i'm not sure what benefits this is going to give me. Please could someone explain what Dynamo is useful for and how i can use it?

    Thank you!

    Hi,

    It all depends on what do you use Revit for, Architectural? Structural? or MEP!??
    There are some tasks that can be streamlined regardless, like creating views, sheets and placing views on relevant sheets.
    Again, this is only beneficial if you are working on big projects with lots of views and sheets. Dynamo can automate lots of tasks that are repetitive and time consuming.
    Have a look on dynamo forum to see some example of what people are using it for.

    What you can do with Dynamo is (almost) only limited by your imagination.
    I've written graphs to:
    • Align Views on Sheets
    • Renumber Details
    • Create Space Planning 3D layouts
    • Create auditorium seating layouts
    • Fix the 2016 upgrade Text problems
    • Add Levels to a project
    • Add Sheets to a project
    • Randomize the panels in a Curtainwall

    Others have created curved surfaces, or Generative layouts for towers

    The Dynamo Primer is a good place to start as to how Dynamo works

    I would ask;
    Can you take your current work process and write/draw it as a series of clearly defined steps? Are a lot of these steps repetitive manual work?
    If you can define exactly what you need to do in such a process then you can probably make a Dynamo script to do it for you and spend your time doing something else more interesting

    Basically everything that revit should be able to do but cant via the limitations of the user interface.. Dynamo can do better. I wouldnt work without it any more.

    Dynamo's effectively a "quick" programming method for Revit. Without the usual type-text-int-some-script programming language that you usually get as a macro in other languages. It's based loosely on the same concept of Grasshopper for Rhyno. Called a "Visual Programming Language".

    This means you can literally achieve things which is simply impossible to do manually, or to perform repetitive tasks all at once with a single instruction from yourself. If you can think of a pattern of things, done each time at some specific point you could just calculate, then it would always be quicker, easier and less error prone to do it through Dynamo instead.

    E.g. say you've got some long section you wish to place on multiple sheets. Instead of you duplicating and adjusting the crop for each view and then place each of them on a sheet manually. Let Dynamo do that for you. It's going to be much more consistent anyway, not just a lot quicker.

    Even creation of models it blows the socks off manual drawing in some cases. If there's any sort of repetition of a pattern it can do these modelling shapes a lot more accurately, faster and much easier to adjust than any human could have done. Just have a gander through the samples shown here: Dynamo BIM . One of which I did several years ago when I was asked to have a sloping balustrade going around several floors in an atrium - the slope would change to follow the organic shape of the atrium https://www.revitforum.org/dynamo-bi...h-closest.html though note Dynamo itself had a bit of an issue and I needed to extend even Dynamo itself - by get this, writing extra programming scripts in Python.

    Another I did much less creative, but also saving me lots of time: https://www.revitforum.org/third-par...ate-items.html. I.e. just to look through a parking basement (9 levels deep with 6000 parking bays) after several people have worked on it adjusting ramps and placing islands, stairs, etc. We found lots of bays becoming duplicated, perhaps slightly off exact positions. I.e. parking count was out. Now instead of re-doing all of those, let Dynamo find bays which are "too close" to one another, then mark them so you can either just delete all, or be able to zoom to them from a schedule. Much easier and faster than to manually eyeball each bay.

    Probably one of the most important uses of Dynamo which hasn’t been mentioned yet, is the interoperability between software packages. Most designers don’t use Revit as a design tool due to the many limitation in the software and therefore have to rely on general modelers like Rhino or SketchUp. This means that you probably have to start from scratch once you’ve reached CD. Importing dumb geometry directly into Revit is far from ideal as well. Dynamo acts as a bridge between the design or fabrication software package and Revit and allows you to spoon feed Revit with data to either create native Revit geometry (if it’s not too complex), drive existing geometry or feed data into the model.

    Just saw this. Very true. An important use case when a project demands you wedge square pegs through round holes. Oh this type of stuff just makes me laugh. What a waste of effort.
