Technical Tip - Verisurf NIST Test

Technical Tip - Verisurf NIST Test


The NIST Test is in the Measure Ribbon Bar under the Report controls. Select to execute a Digital Artifact Verification Process that tests and verifies the algorithms Verisurf Software uses. The United States of America’s National Institute of Standards and Technology (NIST) provides the Algorithms. The current standard for testing is Lines (2D and 3D), Circles (2D and 3D), cylinders, cones, and spheres is ASME B89.4.10-2000 of Methods for Performance Evaluation of Coordinate Measuring System Software.

NIST has provided a Data Set to Verisurf Software; this dataset simulates measurements from a CMM and contains form error and measurement errors per the ASME Standard listed above. When the NIST Test Button is selected, the selected dataset is loaded; a fit is executed, compared to the NIST standard, and then a report is generated in the Data Tree.

Here is a link to the official NIST web site on Algorithm Testing:


  1. Start a New File without a CAD model or measurement data.
  2. On the Measure Ribbon Bar, select NIST Test

  1. In the NIST dialog (below), select the algorithms to test, choose Select All to verify all displayed algorithms in Verisurf.
  1. Verisurf provides the location of NIST Test Data at the top of the dialog box. 
  1. After selecting any or all test types, choose OK in the NIST dialog to populate the Data Tree with Features; Report generates and populates the Auto Inspect Manager (shown below):


The NIST test results can be printed or saved to the computer hard drive, network, or external storage device. Using the Report Manager, you can generate; PDF, HTML, Excel, Word, PowerPoint, Text, or Database reports of the NIST Test results.

  1. On the Data Tree, double left-mouse click on the Report titled NIST Report1 to open the Report Manager.
  2. Select the type of Report you would like to generate.
