Board Geometry / DESIGN_OUTLINE vs. OUTLINE And What Are the Real-World Implications?

Electro Node

Hi everyone,

I've always been a bit confused about the difference between Board Geometry / DESIGN_OUTLINE and the legacy Board Geometry / OUTLINE subclasses in Allegro X PCB Editor.

If the board boundary is defined using Board Geometry / OUTLINE instead of DESIGN_OUTLINE, could that cause any issues during manufacturing, fabrication outputs, MCAD exchange, or other downstream processes? Or is it still generally acceptable in production designs?

I'd love to hear how others are handling this in their workflows. Have you encountered any problems, benefits, or best practices related to using one versus the other? Looking forward to learning from your experiences!

Best Regards,

    Take a look at the parsyseda YouTube channel and search for this subject. There is a video going through why you really should be using the newer subclasses. Outlines could be lots of small segments along the same axis which would have lots of implications for export data and mcad data. Design_Outline and cutout must be closed shapes. This is now also used for the 3dx canvas.

    Hello steve,

    Thank you for the explanation and for pointing me to the ParSysEDA video. The distinction between the legacy OUTLINE subclass and the newer DESIGN_OUTLINE/CUTOUT subclasses, particularly the requirement for closed shapes and the implications for MCAD integration, export data, and 3DX Canvas, is very helpful. appreciate the insight and will definitely explore the video for a deeper understanding

    Best Regards,
