Presentation features have been overhauled for more realistic client walkthroughs and better technical clarity:
3D Dimensions & Text: For the first time, you can add dimensions and text directly within 3D views to clarify details during presentations.
Dynamic Cross-Section Slider: You can now interact with the design while the slider is active, adjusting the cutting plane on the fly without reopening the tool.
Physically Based Ray Tracing (PBR): Includes path-tracing settings and the ability for emissive materials to cast actual light, creating much more realistic lighting environments.
Enhanced Materials: New anisotropic properties improve the look of metals like stainless steel, and a "clear coat" property adds depth to surfaces like polished wood or car finishes. 🏗️ Advanced Building Tools Significant updates to structural design include: Chief Architect Premier X16 (v26
Deck & Roof Control: New deck framing controls and a "flat header" option for doors and windows simplify modern architectural styles.
Truss Direction & Girder Lines: New lines clearly indicate roof framing intent, and specific girder lines have been added for better structural detailing.
Poché Fill: High-contrast fill can now be applied to walls and platforms across plan, elevation, and 3D views for sharper, professional-grade documentation.
