*Help Needed* - tutorial: reduce errors with point cloud in infraworks

[Anonymous]

Thanks in advance,

I've been having a hell of a time loading the point cloud from this tutorial. It seems that; on all the minimum settings, the point cloud wants a billion GB to load. I've got 50GB free space on this HDD.

Help?

P.S. I dropped a PNG capture of the loading screen. It's been giving me an error message all day yesterday.
P.P.S. Confirmed: error message occurs today as well.

@Anonymous Can you please add little bit more details like what is your point cloud size, are you having one RCS or multiple RCS with 1 RCP, is processing still continue giving you the error message to you get the error before or after processing is run?

Thank you,

First thing I did was download the tutorial's sample zip file.

After extraction, the folder is about 12-13 GB (12.4GB).

The RCP file itself is 800KB (748KB). 

I load the RCP file so that it appears on the map, but processing for the Point Cloud Terrain fails every time.

On the attached screenshot the "Start Processing" option never completes without an error.

P.S. If I don't hear from you today, have a great weekend.

Do you have link to that tutorial for me to check it out?

Excuse me!

I found a work-around. Steps 6-11 on page (31%) of the tutorial can be omitted entirely.

For clarification, these are the steps which seem to cause the issue, on page~4:

5. Now we want to classify the point cloud and run the terrain analysis tool. Select the “InfraWorks” icon and select the icon. From there, you will find several options, including “Point Cloud Terrain”, “Point Cloud Modeling”, “Point Cloud Themes”, “Linear Feature Extraction” and “Export Point Cloud…”.

6. Select “Point Cloud Terrain”.  

7. In the “Point Cloud Terrain” window that pops up, you will see a list of “Processing Rules”. Here you can edit “Ground”, “Linear” and “Vertical” features. We will set all of those to “Optimum”. 

8. Turn off “Override Model Point Cloud”. We want to have the raw data and a new point cloud that it’s going to create. It will create a new proposal called “ProcessPointCloud”.

9. Choose to export “All Points” in the “Export Processed File”.

Your Point Cloud Terrain settings should look something like this:

10. Choose a location to save it in by clicking the link next to “Save File”.

11. Click “START PROCESSING”. Depending on the size of your project, this may take some time as it is classifying millions of points and allowing them to model features.

I'm okay with omitting this processing step, because Infraworks let's me classify the points regardless of running through it.

@Anonymous It sounds like the sample data provided already got the classification done and hence you might not need to run it again. But in a real project, if you got some point cloud data you can use those steps to generate terrain. I am glad you can move on with your course/tutorial but I will reach out to the course administrator to make sure we make the necessary update if needed.

Thanks,
