How Do I Trim a STL File in SolidWorks?

by

Are you working with STL files in SolidWorks and need to trim or remove certain parts of the model? Trimming an STL file can be a useful technique when you want to modify or simplify a complex model. In this tutorial, we will explore different methods to trim an STL file in SolidWorks.

Method 1: Using the Split Tool

If you want to trim specific portions of your STL file, the Split tool is a great option. Follow these steps:

  1. Step 1: Open your STL file in SolidWorks by going to File > Open.
  2. Step 2: Once the model is open, go to the Insert tab and click on Features > Split.
  3. Step 3: In the Split PropertyManager dialog box, select the face or plane that you want to use as a cutting tool.

    This will define where the split will occur.

  4. Step 4: Click on the portion of the model that you want to remove. The selected area will be highlighted.
  5. Step 5: Finally, click on the green checkmark to complete the split operation. The trimmed portion will be removed from your STL file.

Method 2: Using Extrude Cut

If you need to remove a specific thickness from your STL model, using the Extrude Cut feature can be helpful. Here’s how:

  1. Step 1: Open your STL file in SolidWorks.
  2. Step 2: Go to the Features tab and click on Extruded Cut.
  3. Step 3: In the Extrude PropertyManager, select the face or plane where you want to make the cut.
  4. Step 4: Specify the direction and depth of the cut by entering values in the appropriate fields.
  5. Step 5: Click on the green checkmark to complete the extrude cut. The specified portion will be removed from your STL file.

Method 3: Using Split Line

If you want to trim specific surfaces or faces of your STL model, you can use the Split Line tool. Follow these steps:

  1. Step 1: Open your STL file in SolidWorks.
  2. Step 2: Go to the Sketched Curve tab and click on Split Line.
  3. Step 3: Select a sketching tool (e.g., line, spline, arc) and draw a closed loop around the area you want to trim.
  4. Step 4: Once you have completed sketching, click on the green checkmark to generate a split line.
  5. Step 5: Now go to the Delete/Keep Body, select the unwanted portion of your model, and press Delete on your keyboard. The selected area will be removed from your STL file.

In Conclusion

In this tutorial, we explored different methods to trim an STL file in SolidWorks. Whether you need to remove specific portions, cut through the model, or trim surfaces, SolidWorks provides various tools to accomplish these tasks efficiently.

Experiment with these methods and choose the one that best suits your requirements.

Remember, working with STL files requires attention to detail and precision. Always double-check your changes and save a backup of your original file before making any modifications.
