Verisurf MBD
Model Based Definition

Create functional 3D GD&T on CAD models and apply imported GD&T automatically to your inspection and reporting workflows for the ultimate in process control.

Verisurf MBD (model based definition) allows you to create or import and edit CAD models with ASME Y14.5-compliant GD&T from PMI (product manufacturing information) or FTA (functional tolerancing and annotation) including manufacturing data, dimensions, tolerances, and engineering notes. Semantic tolerances for GD&T Profile and Position callouts as well as Datum Targets can be automatically applied in live inspection, CMM programs, tolerance analysis, and QA reports. Powerful dimensioning tools that are easier to use than typical CAD tools, make it simple to add dimensions, angles, thicknesses, and more to aid in viewing and reporting.

Automatically add AS9102/PPAP inspection balloons to dimensions and callouts
Create GD&T control frames visually and functionally linked to CAD features
Provide model-based, interactive GD&T that is applied during real-time inspection as well as in CMM programs and report output
Frequently needed dimensions such as distance, angle, diameter, thickness, etc., easily created for viewing and reporting
Unique graphical display of text and symbols always facing forward making them easy to read in screenshots and reports
Datum targets may be automatically used for functional, precise, model-based alignments for superior process control

GD&T Callouts

  • Create GD&T control frame (callouts) with nominals, tolerances, modifiers, datum references, etc
  • MBD/GD&T is functional and CAD feature associative for Profile and Position
  • Callouts are hotkey resizable for better viewing and screenshots

User-Facing Annotations

  • MBD remains screen forward and user-facing for better viewing, screenshots, and reports
  • Text, annotations and symbols maintain a fixed size even when zoomed in or out
  • Hotkeys easily toggle annotation scale/size up and down

Add/Import Dimensions

  • Create accurate dimensions from easily and reliably selectable anchor points
  • Forward-facing text that is hotkey resizable with for clarity
  • Import dimensions from compatible, native CAD files such as CATIA

Interactive GD&T

  • MBD is enabled as “interactive GD&T” which sets tolerances for Profile and Position
  • In Verisurf live BUILD/INSPECT mode MBD tolerances are applied in real-time display of in or out of spec, reflected in informative color and sound feedback

Automatic Datum Alignment

  • MBD Datum Targets may be used for Verisurf’s powerful AUTO ALIGN
  • Datum targets create an automatic, precise, model-based alignment
  • Alignment from datum target specific locations provide repeatability and superior process control

Gap & Flush Measurement

  • Set gap & flush callouts for display as part of MBD
  • Creates the nominal locations and values for gap & flush inspection
  • Gap & flush MBD is used to create and then measure via automated inspection plans, ideal for scanned pointclouds and meshes

Captured Views

  • Allows one-click toggle of CAD levels/layers and MBD on/off states to quickly change what’s on the screen
  • A significant productivity tool that eliminates excessive mouse clicks and hunting for the desired view of the model
  • Captured Views can be imported from native CATIA models

Automate CMM Programming

  • Use imported MBD (GD&T, PMI, FTA) to create a CMM or automated inspection program
  • Automatically utilizes the nominals and tolerances from the model
  • Datums assigned from MBD

Automatic AS9102/PPAP Balloons

  • One-click addition of inspection balloon IDs to dimensions and GD&T callouts
  • Quick and easy setup for AS9102 and PPAP reports
  • Balloon IDs carry over to inspection reports and CMM programs

The Verisurf Model-Based Definition (MBD) Manager includes all of the Tools and Utilities listed below. MBD annotations appear in the Operations Manager tree and in the graphics area and can easily be added, edited, or deleted.

Label a feature as a datum.

Label a feature with a datum target.

Control frame – assign an MBD (GD&T) callout to a feature.

Apply a distance dimension between 2 points or parallel planes.

Apply a dimension to a part thickness.

Apply a dimension to hole diameters.

Apply a hole radius dimension.

Apply a dimension between planar and angular surfaces.

Dimension a point coordinate.
