Analyze

Once Project Setup is complete and you’ve added your geometry and point cloud to Verity with Add to Verity, you’re ready to Analyze. The algorithm attempts to perform most of the verification work for you automatically; finding the Installation Status, best-fitting the As-Built clone geometry to the pointcloud, and producing translation metrics. Once analysis is done, however, you’ll still want to ensure you perform a Review process like you would with any automated algorithm.

The purpose of this article is to cover the Analyze algorithm in a broad manner. For more detailed information on the Analyze algorithm refer to the Analyze FAQ.

Analyze

To start an analysis, click the Analyze button in the left-hand sidebar.

If this is your first time analyzing after adding new geometry and pointcloud data, Verity might ask for you to save the Host project to preserve the geometry links. Ensure you click Yes to continue.

An Analysis Parameters dialog box will appear. Select your Scan data type, workflow, Tolerance and Indoor status.

First, Choose your Scan data type from the dropdown. These various options change which algorithm is used as well as the expected noise advanced setting.

Second, Choose your workflow from the dropdown.

The most important parameter to adjust is the Tolerance.

The Tolerance value you set is the value used when determining if an element is Out of Tolerance compared to its As-Built location (if one is found). Adjusting the Tolerance values is possible once the analysis is complete, but it’s often easier to ensure you are adding elements of equal tolerance requirements to Verity before analyzing.

If most of your project’s scans were taken indoors, check the Indoor Project checkbox; otherwise leave it unchecked.

Canceling the Verity Analysis

When the Cancel button is pressed, Verity will take some time to safely exit the analysis and prevent corruption. Verity will then discard any calculated data up to that point, and you can safely continue working or close Verity.

The Cancel Analysis button is not currently available for Verity for Revit, but will be implemented in a future version.

What is a Verity Analysis?

The Verity Analysis is essentially a best-fitting and translation/rotation calculation algorithm.

During the Add to Verity and Analysis steps, Verity performs these functions:

• Import Scan Data to Verity
• Import Geometry Data to Verity
• Create a section box around the Geometry to isolate nearby pointcloud data
• Clone the provided Geometry
• Best-fit the cloned Geometry to the point cloud
• Calculate Installation Status, Conformance to Tolerance, and Translation and Rotation Metrics

For more information on the Verity’s various metrics and results, refer to the Review section.

Analysis Duration

It is incredibly difficult to determine the duration of a Verity analysis due to the complex combination of factors: hardware of the processing machine, quality and density of the point cloud data, complexity of geometry, and project size just to name a few.

Our recommendation is to keep analyses concise and actionable. If you try to analyze 150 scan locations against 5000 elements; Add to Verity, Analysis, Review, and Reporting will all take significant time and delay you from getting reporting out to the people who need it. Keeping analyses focused on specific systems, areas, scope, etc. is key to producing useful reporting data quickly.

For more information on what to expect in regards to analysis duration, consider the Analyze FAQ article.

Future Analyses

Once the analysis is complete, you can proceed with the Review process. If you have other geometry to analyze with different tolerance requirements or want to run the same geometry at a different tolerance, you’ll want to utilize the Analyses options that are found in the Verity Menu.

Copying Items to a new Analysis and New Analysis will be most often used when producing additional analyses. Open Analysis is often used when returning to previous work. For more information on these tools, refer to the Project Setup.
