Master 3D Texturing in SOLIDWORKS 2019: Create Realistic, Layer‑Line‑Free Prints

Since the release of SOLIDWORKS 2019, the built‑in 3D texture (displacement mapping) feature has opened up new possibilities for mechanical designers. Traditionally a staple of artistic modeling tools like Maya and 3DS Max, 3D texturing now lets engineers add realistic surface detail, hide layer lines, and even simulate knurling with ease.

In this step‑by‑step guide, we’ll walk through how to apply a 3D texture to any part, from choosing the right image to fine‑tuning the detail level and offset.

Step 1: Pick or Create a Heightmap Image

Choose a greyscale or black‑and‑white image that represents the surface profile you want. SOLIDWORKS interprets lighter tones as raised features and darker tones as recessed ones. While any black‑and‑white image will work, heightmaps—images that map elevation to brightness—produce the most predictable results. Keep the file size moderate; larger images increase processing time.

Step 2: Select the Faces to Texture

Highlight the surfaces that should receive the texture. In this tutorial, a simple block is used, and both flat and curved faces are selected.

Step 3: Import the Image and Create an Appearance

Choose the image file from your computer. SOLIDWORKS will prompt you to save it as a new appearance. If the image already exists in your design library, the prompt will be skipped.

Step 4: Fine‑Tune the Appearance

Adjust placement, mapping, and scale. “Automatic” placement and “projection” mapping work best for flat surfaces, while “surface” mapping is ideal for curves. You can also rotate and scale the image to match the geometry.

Step 5: Apply the 3D Texture Feature

Navigate to Insert > Feature > 3D Texture. Every face with an appearance will display a checkbox. Check all relevant faces, then set the detail level (≈60% for a balanced look) and the offset distance (0.5 mm is a good starting point). By default, lighter areas will protrude while black remains flush; the “white up, black down” option can be toggled if you need the opposite effect.

Best Practices and Tips

3D textures are most effective on vertical or angled surfaces where the raised features can be clearly seen. Printing with a smaller layer height amplifies detail and further smooths the surface. This technique is especially valuable for prototypes that need to resemble final products or for parts where surface finish is critical.
