How to Integrate Point Cloud into Google SketchUp

Written by

You can create an accurate blueprint for modeling of a real object in SketchUp using free 3D photo-based scanner. Points created with www.my3dscanner.com  will serve as construction marks for SketchUp model.  Later you can link construction points automatically or manually to create complex polygonal replicas of the real world in Sketch Up.

Let me guide you how to do it. There are 4 main steps:

1.       Scan an object and receive a 3D point cloud (if you don’t have one yet)

2.       Reduce the density of the point cloud (optional but recommended)

3.       Turn the point cloud into Sketch Up readable format

4.       Import the point cloud into Sketch Up

 You will need the following free (except MS Excel but use their trial or borrow) tools:

www.my3dscanner.com to create 3D scan of a real object with your digital camera. It is free on-line scanning service (no need to download)

MeshLab is free software to view and manage point clouds (optional) - download

Microsoft Excel

Google SketchUp

Cloud_v71.rb  is SU7 plug-in - download


Step 1: Scan an object - create point cloud

Create a 3d project (e.g. my3dproject) with your digital camera or a mobile phone at www.my3dscanner.com :

  • Read tutorials
  • Register
  • Take and upload photos
  • Download  result: a zipped 3D point cloud in  .ply format. Download my3dprogect.zip   to your computer from My Studio/My Projects.
  • Unzip it to have your point cloud my3dproject.ply file ready for SketchUp integration.

Step 2: Reduce the density of your point cloud (optional but recommended step)

Your point cloud most likely will be very dense. It is good for visualization but bad for Sketch Up modeling. You need to end up with 2-5,000 points maximum. To sub-sample a point cloud to make it less dense use MeshLab:

File -> Open -> my3dproject.ply

Filters -> Sampling -> Clustered vertex Subsampling  -> Dialog Box.

Dialog Box: Apply, Close

This way you will apply Default Values in a this dialog box. If you will to sub-sample only some parts of your point cloud, check “Select” box. You can play with values in the dialog boxes (all your attempts will be saved in different layers as described below). Experiment!

Apparently you will not see the result immediately.

To view it, go to View -> Show Layer Dialog.

Switch visibility off for my3dproject in the right window. You will be left with Cluster Samples (in yellow) layer which is less dense point cloud. This is exactly what we wanted to achieve.

Click on Cluster Samples and:  File -> Save As - > Name: my3dproject, format: Stanford Polygon Format (*ply) -> Save

In the next pop-up window unmark Binary encoding and click OK.

Now you have your my3dproject.ply point cloud reduced.

Step 3: Turn your point cloud into csv file

Start Excel: File -> Open -> my3dproject.ply  -> Text Import Wizard:


Text Import Wizard Step 1


Check Delimited


Change “Start from the line” to 11 (if you have skipped step 2 of this tutorial, change to 9). You are just deleting the header of the file, so adjust the row number respectively.


Do not change other settings. Next


Text Import Wizard Step 2


Check Space -> Next

Text Import Wizard Step 3

Check General -> Finish

You will have a table with 3 rows of digits (or more if you have skipped Step 2)

We are almost done:

File -> Save As -> Other Formats -> File name: my3dproject, File type: СSV (Comma delimited) (*.csv) -> Save -> Yes

Now you have my3dproject.csv ready.


Step 4: Import .csv  into SketchUp

Download and install cloud_71.rb plugin into Google SketchUp. It will add an option Points Cloud in File menu of SketchUp.


Start Sketch Up and import point cloud:


File -> Points Cloud -> Import - > my3dproject.csv -> OK -> Dialog Box “Points Cloud Options”


Data delimiter:                 ;

Import unit:                    Meters

Flatten Z coordinate:        No



Click OK. Make sure the values you enter are the same as in the screenshot above.


Click OK in the next screen.


Then click OK in “Additional Options” window.


Wait, do not rush Sketch Up!


The last step is a window “Triangulate the point cloud?”

 I’d rather say NO since there are better options to triangulate (I will talk about them  in my next tutorials, ) but you can also click “yes” and wait (SketchUp may crash at this point of time if point cloud is too big). If you do not like the triangulation/mesh result, just kill the layer, not the construction points.

This is it. Your scan is in SketchUp. It is not as pretty as in www.my3dscanner.com (you will get sparse point cloud with no color), but real builders use crude concrete and steel bars, not artistic colored points, right?

Do you want to triangulate/mesh the point cloud in SketchUp?  The next tutorial is coming!

    Dustin, it's a rather complex and lengthy method. I really can't tell you what had gone wrong given your sparse description of the problems you had faced.

    I've gone though all of the steps yet when I import the csv file into sketch up it does not show the sample line of data in the opening window.

    I've set up my .csv with tabs and spaces and everything seams to be working.

    Is this because I have to many points in my model? Where am I going wrong?

    Thanks in advance
