How Do I Get Rid of the Black Lines in SketchUp?

by

In SketchUp, black lines can sometimes appear on your model, which can be distracting and affect the overall visual appeal. Fortunately, there are a few techniques you can try to get rid of these black lines and achieve a cleaner look for your SketchUp designs.

1. Soften/Smooth Edges

If you notice black lines appearing along the edges of your model, it may be due to the default sharp edges setting in SketchUp. To solve this issue, you can use the Soften/Smooth Edges feature:

  1. Select the desired geometry by either triple-clicking on it or using the Select tool (shortcut: Spacebar).
  2. Right-click on the selected geometry and choose “Soft/Smooth Edges” from the context menu.
  3. In the Soft/Smooth Edges dialog box, adjust the angle slider to determine which angles should be softened or smoothed. Increasing the angle will soften more edges.
  4. Click “OK” to apply the changes and see if it eliminates the black lines.

Note: The Soften/Smooth Edges feature only affects how SketchUp visually displays edges and does not modify or alter your model’s geometry.

2. Adjust Face Style Settings

If you still experience black lines after applying Soften/Smooth Edges, you can try adjusting your Face Style settings:

  1. Go to the “View” menu at the top of SketchUp’s interface.
  2. Select “Face Style” from the drop-down menu.
  3. In the Face Style sub-menu, try selecting different options such as “Shaded,” “Shaded with Textures,” or “Hidden Line” to see if it resolves the issue.

Note: Choosing the “Hidden Line” option will remove all lines in your model, which may not be desirable depending on your project requirements.

3. Use Styles and Templates

If the previous steps did not solve the problem, you can experiment with different styles and templates available in SketchUp:

  1. Open the “Styles” window by going to the “Window” menu and selecting “Styles”.
  2. In the Styles window, you can try applying different pre-defined styles or create your own customized styles.
  3. Click on a style thumbnail to apply it to your model and check if it eliminates the black lines.

Note: Applying a style may change other visual aspects of your model, such as colors and shading. So make sure to find a style that suits your design preferences.

4. Update Graphics Card Drivers

If none of the above methods work, it is possible that outdated or incompatible graphics card drivers are causing the black lines issue. To update your graphics card drivers:

  1. Determine which graphics card you have (e.g., NVIDIA, AMD, Intel).
  2. Visit the official website of your graphics card manufacturer.
  3. Navigate to their support or drivers section and search for the latest driver for your specific graphics card model.
  4. Download and install the updated driver following the provided instructions.

Note: Updating graphics card drivers can help resolve various graphical issues in SketchUp, including black lines.

In Conclusion

If you’re experiencing black lines in SketchUp, try using the Soften/Smooth Edges feature, adjusting Face Style settings, applying different styles and templates, or updating your graphics card drivers. By following these steps, you should be able to eliminate those unwanted black lines and enhance the visual quality of your SketchUp models.
