    If you're able to reproduce the issue, it would help if could you submit a bug-report as described in this document:
    https://unity3d.com/unity/qa/bug-reporting

    It's important that you report these issues together with a reproduction project if you want them to get fixed. If you don't do it, it might be a long time until someone else reports them or until Unity Technologies find them.

    After you submitted the bug-report, you receive a confirmation email with a bug-report Case number. Please post the Case number (number only, not the link) in this forum thread for Unity staff to pick up.

    Thanks in advance :)

    Hi, this steps where tried on: 2018.4.7f1 / 2019.2.2f1 / 2019.2.3f1

    To reproduce it:
    1- donload de .rar file here (https://drive.google.com/open?id=1y9bsYLPozL1G_2pG_EtvQpA6xm1H1dzB)
    2- decompress it somewhere;
    3 - Into de TAB "Projet", create a folder named "Sketchup" inside "Assets";
    4 - drag and drop "Sunset Externo R3" folder inside the "Sketchup" folder;
    5 - drag and drop "Sunset Externo R3.dae" inside the "Sketchup" folder;

    PS: I already tried with .fbx file too, the same slowness happens.
    PS2: I tryied in one other computar, an I7, just afew faster, it took about an hour to import the asset.

    regards

    Our developers have looked at this issue, and the main cause of it is not the size of the asset - in this particular case, it's the fact that the Sketchup document has a very large number of nodes which translate to huge hierarchies and long importing times.

    Sadly, there's not much we can do to improve the import time. We would recommend you to split the scene into smaller chunks or even to try and flatten the hierarchy inside Sketchup as much as possible. Also, Importing the .skp file directly in Unity might be faster.
