Comprehensive Verification Checklist

1

Dimensional Accuracy Verification

Compare critical dimensions between source and converted files. Check overall bounding box, key features, and geometric relationships. Use measurement tools in both source and target applications.

2

Geometric Integrity Assessment

Inspect surfaces for gaps, overlaps, or missing geometry. Verify curve continuity and surface normals. Check for proper closure of solid bodies and correct topology.

3

Material and Appearance Check

Verify that materials, colors, and textures are properly preserved. Check texture mapping coordinates and material property assignments. Validate rendering appearance in target application.

4

Units and Coordinate System

Confirm that units are correctly interpreted and converted. Verify coordinate system orientation and origin placement. Check scaling factors and dimensional units consistency.

5

Assembly Structure Validation

For multi-part assemblies, verify that component relationships and constraints are maintained. Check part positioning, assembly hierarchy, and mating conditions.

6

Target Application Testing

Open and test the converted file in its intended target application. Verify all required functionality works as expected. Test specific workflows and operations relevant to your use case.

Common Error Solutions

❌ Geometry Healing Failures
Broken surfaces, gaps, or invalid topology preventing proper conversion.
✅ Solution:

Use CAD repair tools before conversion. Simplify complex geometry, stitch surfaces, and remove degenerate elements. Consider using Total CAD Converter's advanced healing algorithms.

❌ Unit Conversion Issues
Incorrect scaling or dimensional mismatches between source and target formats.
✅ Solution:

Always specify units explicitly in conversion settings. Verify unit interpretation in target software. Create measurement standards for critical dimensions.

❌ Material Loss
Colors, textures, or material properties disappearing during conversion.
✅ Solution:

Choose formats that support materials (OBJ+MTL, COLLADA). Enable material export options. Package texture files with geometry files.

❌ Large File Sizes
Converted files becoming too large for practical use or software limitations.
✅ Solution:

Optimize mesh density before conversion. Use appropriate precision settings. Consider level-of-detail approaches for complex models.

❌ Assembly Hierarchy Loss
Part relationships and assembly structure not preserved in converted files.
✅ Solution:

Use formats that support assemblies (STEP, COLLADA). Export assembly structure explicitly. Consider converting components individually if needed.

❌ Precision Loss
Fine details or precise dimensions becoming approximated or lost.
✅ Solution:

Increase precision settings in converter. Use high-precision formats (STEP, Parasolid). Validate critical dimensions post-conversion.

Industry Standards Compliance
