Tool palettes can now be shared with project collaborators by leveraging Connected Support Files with Autodesk Desktop Connector. When the Project Administrator updates the tool palette, the changes apply to all users who open collaboration projects within the same Autodesk project.

The Selection List Property dialog box has been redesigned to allow individual unshared selection lists to be converted to shared lists across P&ID and 3D piping classes, and vice versa.

Create an isometric drawing with multiple sheets, significantly reducing the total number of isometric drawings in a project.

Estimate the completion rate for 3D piping against P&ID design, displaying it in the P&ID Line List palette, providing additional insight into project progress.

Added more selection methods for instruments, like those with the same loop number, allowing you to easily select and change properties of instruments more efficiently

Project functionalities see improvements with shared selection lists, a modern project backup and audit interface, and the ability to update project names directly from Project Setup, ensuring consistency and ease of management.

This is a continuous improvement for the new Spec Editor introduced in 2026 release, with numerous experience improvements in Spec Editor, Catalog Editor and Branch Table.

AutoCAD Plant 3D features new substitution menu options for reducing fittings and equipment nozzles. Enjoy optimized performance with a default visual style adjustment to Shaded. Equipment body previews and better port name displays also improve visualization.

Connected Support Files extends integration with Forma Data Management, giving CAD managers centralized control over cloud-based support files. Project-aware tool palettes and CUI ensure the correct resources load automatically, streamlining administration and consistency.

Collaborate on plant design models across project teams and maintain compliance requirements—all in a cloud-based common data environment.

Use in-context AutoCAD commands to make P&ID drafting easier. 

The Plant 3D toolset is delivered with standard symbol libraries in the tool palettes. These include PIP, ISA, ISO/DIN, and JIS.

Quickly identify possible errors by scanning P&IDs for data consistency according to user-definable rules.

Quickly create 3D plant models using parametric equipment modeling, structural steel libraries, and project-specific piping specifications using industry standard piping catalogs. 

Create and edit equipment using parametric templates to help you build plant layouts faster.

Lay out structures, stairs, ladders, and railings using industry-standard steel sections including AISC, CISC, and DIN.

Customize piping specifications to meet project-specific requirements. Include industry-standard components as well as customized components.

Extract piping orthographic drawings directly from the 3D model and update them as the 3D model is being updated.

Create industry standard/project-standard piping isometric drawings directly from the 3D model.

Define report formats for the project and automatically populate the data directly from the 3D model.

Work with other industry disciplines to create BIM models for the plant.
