Sitius™ Part Verification



Sitius™ Part Verification (SPV) is a software product used to compare an actual detail to its corresponding CAD model. A set of 3D coordinates describing the physical part is compared to its computer representation in seconds. The points can be obtained with Manual or DCC Coordinate Measuring Machines, Laser Trackers, Theodolites, Laser Scanners, Optical Systems, etc.


  • Save time - very fast ( Complete inspection with SPV - under 1 hour vs. Conventional Inspection - 1 day or longer )
  • Improve quality - Verify complex geometry in minutes and with high accuracy
  • No data translation, no data duplication - uses native CAD
  • Utilizes existing software, hardware and knowledge
  • Short learning curve
  • Automatic probe radius compensation
  • Finds material side for surfaced models
  • Compensates the probe radius against solid faces and edges
  • Handles parts of any size or complexity with ease
  • Recommends new tooling hole position
  • Very fast (3000 trimmed surfaces at a rate of 100 points per second)
  • Proven product (used in over 3000 inspections since 1993)


  • Runs within the native CAD  system
  • Best-fit alignment
  • Easily converts the points to an off-line program
  • Graphics and text reporting
  • Analysis of results

Best suited for fast verification of

  • Complex geometric shapes
  • One-of-a-kind parts
  • Electrodes
  • Inserts
  • Sheet-metal parts
  • Castings
  • Localized areas
  • On-the-spot checks
