Ray's SketchUp modeling with 3D Scanner Gallery


Hello everyone.

I am Ray from South Korea working at CBT Solutions, a Trimble SketchUp ATC distributor.
We work on a variety of outsourcing tasks to train SketchUp skills in a variety of industries.

In this gallery, I would like to introduce SketchUp modeling work using Point Cloud acquired with 3D Scanner.

  • 3D Scanner: Trimble TX5, TX8, SX10, Geoslam
  • SketchUp Version: 2017, 2018
  • SketchUp Extension: Undet for SketchUp
  • Modeling Accuracy: Less than 5cm (Barge excluded)

[Terrain modeling at Seoul Olympic Park]

[Barge Modelling]

[Modeling penguin village in Gwangju, Korea]

[City Regeneration Project - Traditional Market -]

[National Gugak Center Reverse Design]

I will upload more content in the future. :slight_smile:


Looks great! Thank you for sharing your work.

Could you share some statistics (face count, model size etc.) through an example project?
Scene looks very dense and considering SketchUp known for not handling such high-poly counts, how responsive is the viewport?
Meshes look very clean, do you generate them from point-cloud automatically (or how much manual editing falls into)?


Hi, filibis
I will reply to your question below.

  1. Model Statistics
    [Edges / Faces / File Size]
    Terrain modeling at Seoul Olympic Park: 1,258,613 / 839,063 / 143MB
    Barge Modelling: 272,740 / 85,746 / 15.9MB
    Modeling penguin village in Gwangju, Korea: 435,303 / 228,131 / 68.7MB
    City Regeneration Project - Traditional Market -: 973,884 / 540,503 / 82.9MB
    National Gugak Center Reverse Design: Edges/Faces 230,279 / 109,259 / 20MB

  2. Viewport
    My work was easily viewport controlled in SketchUp.
    However, when PointCloud is displayed in the viewport, it becomes difficult to control.
    I controlled the viewport in such a way as to reduce the number of PointClouds or to make the section box only partially visible.

  3. Mesh Creation
    The terrain can be created automatically by Undet for SketchUp.
    And buildings have to be built by myself considering the average location according to the distribution of the point cloud.

I hope my answer has helped you.

Very impressive work! Thanks for sharing!
Do you think in the near future it would be possible that all meshes would be created automatically?


Wow, thatโ€™s amazing, and a lot of work! What do you use for generating animation/walk through?


In general, irregular shapes such as terrains and caves can be automatically meshed.
And shapes with standard specifications such as pipe and steel structure can also be easily made with a little effort.
However, I think that it is difficult to create a mesh automatically because buildings have to be modeled as planes instead of irregular triangles, even if there is noise in the point cloud.
I suspect that artificial intelligence technologies will solve this problem in the future.


I use Twinmotion. :slight_smile:
