Whether you are adding a serial number to a pipe, branding a consumer product, or engraving text onto a complex mold, placing text on non-flat surfaces is a essential skill for any Siemens NX user.

In this tutorial, we explore two primary methods: Wrap/Unwrap (for zero-distortion) and Project Curve (for quick application).

The Challenge with Curved Geometry

Standard sketching in NX occurs on a flat 2D plane. When you try to extrude text from a flat plane onto a cylinder or a sphere, the letters near the edges often look "stretched." To solve this, we need to map the text to the face's actual surface area.

Project Curve (Best for Irregular/Organic Shapes)

If you are working with a complex, organic surface where "unwrapping" isn't feasible, Project Curve is your go-to tool.

Create a Datum Plane: Position a plane in front of the target surface.

Sketch Line: Sketch a line on this plane that you will use as positioning for the text.

Project: Project the curve on the face that will receive the text.

Place the Text: Set your parameters to the Text window seen below. Remember, you have freedom to change the aspect rations and kerning here.

Divide the Face: Use the Divide Face command to imprint this text on the face.

Use the Synchronous Modeling Offset command to either add or remove material normal to the faces.

Pro Tips for Professional Results

Font Selection: For CNC machining or 3D printing, use simple, "Single Stroke" fonts to reduce toolpath complexity.
Associativity: Always keep your "Project" or "Wrap" features associative. This way, if you change the text string in the sketch, the 3D engraving updates automatically.

Conclusion

Adding text to a design is often the final "polish" that makes a digital model look like a real-world product. By mastering the Wrap and Project tools, you can handle any surface geometry NX throws at you.

Next Steps: Master the Foundations of Feature Modeling

Placing text on a surface is just the first half of the equation. To transform that text into a physical embossed or engraved feature, ensure your foundational modeling geometry is perfectly stable:
