Get started with SpinFire Ultimate – Analysis features (4 of 5)

This series is designed to support your knowledge of SpinFire and expose valuable features.

In our previous articles we covered:

Article 1: How to capture feedback, markups and create user views.
Article 2: CAD calculations (volume, surface area, center of mass, weight, thickness, bounding box)
Article 3: CAD Dimensioning (Smart edge dimensioning, Tube length, Radial, Angular and Linear menus)

In this article, we would like to introduce you to some of SpinFire’s powerful analysis tools:
(Duration: 10 minutes)

  • Draft angle analysis
  • Model compare
  • Rule-based coloring

and remember all analysis results can be saved to a user view, this feature was covered in Article 1.

Draft angle analysis

SpinFire’s Draft Angle Analysis feature allows you to easily analyze a part for the proper draft angle. A draft angle describes the amount of taper for molded or cast parts perpendicular to the parting line. To access the Draft Angle Analysis (DAA) feature, select Draft Angle Analysis from the 3D toolbar and follow these 3 steps:

  1. Select pull direction
  2. Select the draft angle
  3. Select parts/ surfaces


Model compare

You no longer have to play ‘spot the difference’ when reviewing the geometric differences between model revisions.  SpinFire’s Model Compare functionality eliminates any guesswork when comparing two similar parts.  Differences, such as added or removed material, are visually presented by coloring portions of the parts. Watch this video to see how it’s done.

Please note, a visual model comparison might not be the best tool for highlighting very small or fine detailed changes. As results will depend on the tolerance applied to this function and the accuracy of the selected model set (B-rep vs tessellated models).  To more accurately review the differences between models we would advise combining this analysis with additional calculations, such as volume and surface area covered in Article 2.


Rule-based coloring

Rule-based coloring leverages the geometry and metadata of CAD to dissect and review CAD models in creative new ways. Color parts by author, by material, by weight etc.
Rule-based coloring lets you build your own rules to visualize an analysis of your 3D models based on those rules. Rule-based coloring graphically shows where rule matches appear in an assigned color/state. Also shows those areas/parts where the analysis is not available due to the lack of the type of information that the rules are attempting to match.

To color a model based on rules:

  1. Click on the Analysis menu in the 3D toolbar to access rule-based coloring.
  2. Decide how to color parts.
  3. Add rules.
  4. Select all parts or select individual parts.
  5. Click ANALYZE.
  6. View the graphical representation.
  7. View, copy or export the rule-based coloring results.
  8. Export rules if necessary for later use.


We hope this article helps you gain the most out of your SpinFire CAD viewer.
