    Hi Pavel, Thanks for the feedback, sure, what I'm going to do instead is allowing the user to write the input that he wants instead of a dropdown list.

    Thank you very much for this application

    I have a request: would it be possible to invert the value of height and width? because the constraint is often related to height more than width. finally would it be possible to enter the value directly without scrolling the list of dimensions?

    Valentin Noves (Publisher) | May 31, 2019

    Hey David I just added your suggestion and you choose between Height and width

    I wait for 2021 & 2022 update ! ... Pleaseeeeee !!!

  • Great Tool Thank you for Sharing

    Hi Valentin,
       I tried your plugin for Revit 2019 (Ductulator) very nice I have to say. I wrote a program years ago with Visual Basic that I could type in the Duct Size and like yours sort of but I used Depth and calculated. When doing coordination type drawings the depth of the duct is always most important. So just requesting you think about adding that option also.


    Valentin Noves (Publisher) | October 31, 2018

    Hi Bob, Really appreciate your feedback!. I will add that feature to the add-in, it makes sense completely and it should be something easy to do. Regards

  • Great tool

    This tools save us time by not having to re size ducts manually everytime that we need to do it.

    It doesn't work with fabrication elements, hope this is a added in a future release
