The Profile Tool evaluates how a scanned part deviates from its nominal .STEP model under a Datum Reference Frame (DRF). It supports both whole-part Profile and per-feature Profile evaluation, and is the most demanding GD&T Tool in the 3D Auto-Dimensioning suite.
All measurements should be performed on an ROI that roughly orients your part to the correct orientation. The DRF you build inherits this orientation.
The Profile Tool is available in Dimensioning Mode. Generating a part Profile: uploading a CAD file, defining datums and associating them between the part features and CAD features

​
Requirements

Before running Profile, you need:
  • Uploaded .STEP of your nominal part / body. Use the Import Tool in the Toolbar to upload your STEP file. For a focused walkthrough see Nominal CAD Import.
  • A corresponding DRF on both your uploaded STEP file and your scanned part. Three datums are supported in this release. Corresponding datums on each side enable datum simulation for accurate Profile evaluation. See Datum Definition for how to build them.
Voyager uses the labels you assign to datums (for example, A, B, C) to correlate the CAD-side and part-side DRFs. Matching labels make the datum-correlation step in the Profile workflow trivial.

​
Workflow

1

Define datums on your part

In Dimensioning Mode, use the Datum Tool to define datums on extracted features of your scanned part.
2

Upload your CAD

Use the Import Tool to upload the .STEP file of your nominal part.
3

Define datums on your CAD

Use the Datum Tool again to define a corresponding DRF on the imported CAD.
4

Select the Profile Tool

Choose Profile from the Toolbar.
5

Select the uploaded CAD

Pick the imported .STEP body as the nominal reference.
6

Correlate datums

Step through the datum-correlation workflow to pair part-side and CAD-side datums. Matching labels are paired automatically; you can override any pairing manually.
7

Choose Profile scope

Select single feature for per-feature Profile or whole part for full-part Profile.
8

Enter tolerance and submit

Provide the Profile tolerance and submit. The result is rendered as a deviation heatmap with a tolerance-aware pass/fail label.

​
Editing after submission

  • Tolerance can be adjusted after evaluation; the heatmap and pass/fail label update without resubmission.
  • Leader / label orientation and position can be adjusted to organize the scene, just like in the other Tools in this suite.

​
Roadmap

  • Profile probing to read deviation values directly from any point on the heatmap.
  • Expanded datum support beyond the three datums supported today.
