FAQ

Can DrawCAD select a standard flange size?

No. You can name a standard for visual context, but pressure class, dimensions, materials, and compliance must be checked against the authoritative specification.

How should I describe a bolt circle?

Include the number of equally spaced holes, each hole diameter, the pitch-circle diameter, and any angular offset from a centerline.

Is the result suitable for flange fabrication?

No. It is a CAD-style image, not a toleranced manufacturing drawing or verified STEP/STL file. Sealing, pressure, and fabrication details require engineering CAD and review.
