Tip #126: The Measure Vertical Clearance Command

By Erin Johnson posted 10-09-2020 08:06

  

Good morning TBC’ers! Have you ever wanted to measure the clearance from a cross-over bridge down to a road surface to ensure heavy duty trucks can pass through the road? Well, today I will be demonstrating the Measure Vertical Clearance command. The Measure Vertical Clearance command allows you to select a point or CAD object and automatically compute the distance (clearance) between the selection and either the top or bottom of the point cloud at that location. You can then optionally save the distance as a Stored Measurement in the project. 

 

To access the Measure Vertical Clearance command, follow these steps:

 

1. Navigate to the Point Clouds ribbon, and select Measure Vertical Clearance under Measure:

2. In the Measurement direction list, select the direction for which you want to measure the clearance: 

Your selection determines whether the distance is measured upward or downward vertically through the point cloud to the most extreme scan point at that location. In this demonstration, I measured the clearance down from a cross-over bridge down to a road surface. 

 

3. Click in the Point or CAD object selection field and then, in a graphic view, select the point or CAD object form which you want to measure the clearance:

In this demonstration, I selected a point in the graphic view. The results of the measurement are displayed in the Results section:

The measured distance is also displayed in the graphic view:

4. Optionally, click the Save button to save the measurement in your project and display it nested beneath the Stored Measurements node in the Project Explorer

You can double click a measurement in the Project Explorer to view and/ or edit its properties (including its name) in the Properties pane.

 

I hope this tip comes in handy next time you are working with point clouds in TBC!

Hi Robert,

 

Yes, this command was added in TBC v5.30, so it will not be accessible in v5.21 unfortunately. Let me know if you have any more questions.

 

Best,

Erin

Is this a tool that was added in v5.3?  I don't see this is v5.21.
