AutoCAD 2026 introduces an important enhancement to centreline and countermark workflows through the full integration of the CENTERLAYER system variable. This update gives users more precise control over how centerlines and center marks are organised within a drawing, resulting in cleaner, more consistent documentation.

In previous versions of AutoCAD, managing the layer assignments for centerlines and center marks required additional steps. Now, with the improved functionality in AutoCAD 2026, the CENTERLAYER variable can be set or adjusted directly within your workflow—no need to manually change layer settings after placing centerlines or marks.

Here’s What’s New:

• CENTERLINE Command Integration: When creating centrelines, you can now specify which layer they are placed on using the new Layer option.
• CENTERMARK Command Integration: Similarly, center marks can be assigned to a specific layer during creation, streamlining your drafting process.

How to Set the CENTERLAYER:

• At the Command Prompt: Use the new Layer option when running the CENTERLINE or CENTERMARK commands.

On the Ribbon: Navigate to the Annotate tab > Centerlines panel and use the Layer control dropdown to assign or change the layer

This level of integration makes it easier to enforce drafting standards and improves overall drawing organization. By ensuring that centrelines and center marks are automatically placed on the correct layer, teams can reduce cleanup work and maintain consistency across files.

Whether you’re working on mechanical designs, architectural plans, or civil projects, this update in AutoCAD 2026 helps you work faster and smarter, with greater control over your design output.
