About Verify
Verify is an optional Creo Parametric module that you can use to classify and quantify flaws generated in manufactured models when they are compared to design specifications.
Typically, you use a laser scanner to scan a manufactured model. The scanner outputs a file containing a cloud of point representations of the model—usually several hundred thousand in one scan. These point representations are generally spaced very closely to detect and measure surface geometry features that are approximately 15/1000 of an inch. Many laser scanners can achieve accuracy to approximately 25 microns.
Creo Parametric reads in the scan data file and then compares the sampled model to the (nominal) design model, using computer-aided verification techniques. You can quantify the following types of deviations:
Global defects, such as warping and shrinkage
Mid-level defects, such as those caused by improper EDM setups
Highly local defects, caused by surface imperfections
Scan data sets can be in any of the following formats:
ASCII (filename.pts)
IBL (filename.ibl)
IGES (filename.igs)
VDA (filename.vda)
To maintain compatibility with Creo Parametric formats, Verify first creates an assembly. However, Creo Parametric can distinguish Verify assemblies from Creo Parametric assemblies.
The Verify assembly has the following characteristics:
The base component is the design model.
Each scaled and placed scan set is treated as a component part. When you save the assembly, its scan sets are also saved as separate parts.
Each fit and deviation case is treated as a feature of the assembly.
