  TracePro Overview _B[WY  
`%=<R-/#7S  
Like LightTools, TracePro is an solid-modeling based illumination modeling program with a Windows-based interface and CAD import/export capability 2m"_

TracePro modeling capabilities are similar to LightTools but with significant weaknesses that make it harder to use and less flexible, and is especially limited in 3D texture modeling compared to LightTools 2+:'0Krc

TracePro analysis features are similar to LightTools, but LightTools is much stronger as an interactive design AND analysis tool
