How Do You Fill a Surface Body in SolidWorks?

Are you working with SolidWorks and need to fill a surface body? Look no further!

In this tutorial, we will guide you through the process step by step. So let’s get started!

Step 1: Open your SolidWorks file

Firstly, launch SolidWorks and open the file that contains the surface body you want to fill. Make sure you have the necessary permissions to edit the file.

Step 2: Select the surface body

Once your file is open, locate the surface body in the feature tree or graphics area. To select it, simply click on it with your mouse.

Step 3: Access the Fill Surface tool

To fill a surface body in SolidWorks, we will use the Fill Surface tool. You can find this tool on the toolbar or by navigating to Insert > Surface > Fill. Click on it to proceed.

Step 4: Define boundary curves

The next step is to define boundary curves for the fill surface. These curves will act as guides for creating a smooth and continuous surface. You can use existing sketch curves or create new ones specifically for this purpose.

  • Note: The number of boundary curves required depends on the complexity of your surface body and desired outcome.

Create new boundary curves:

  1. Select Create Sketch from the toolbar or navigate to Insert > Sketch.
  2. In the sketch environment, use tools like lines, arcs, and splines to draw your desired boundary curves.
  3. Tips:
    • To ensure a smooth fill surface, make sure your boundary curves do not intersect or overlap.
    • Use the Tangent and Curvature tools to control the continuity between curves.
  4. Exit the sketch environment by clicking Exit Sketch.

Select existing boundary curves:

  1. In the Fill Surface tool, click on Select Curves or navigate to Select > Curves.
  2. In the graphics area, click on each curve you want to use as a boundary. Hold down the Ctrl key to select multiple curves.
  3. Tips:
    • To select all connected curves in one go, click on any part of the curve while holding down the Shift key.
    • If you need to deselect a curve, simply click on it again while holding down the Ctrl key.
  4. Click OK when you have selected all desired curves.

Step 5: Adjust fill surface options (if necessary)

If you want more control over your fill surface, SolidWorks provides various options to adjust its shape and smoothness. These options include:

  • Tolerance: Specifies how closely the fill surface matches your boundary curves. Higher tolerance values result in a looser fit, while lower values provide a tighter fit.
  • Boundary Constraints: Allows you to control how the fill surface behaves at each boundary curve. Options include Tangent, Curvature, and Normal Continuity.
  • Type of Surface: Determines the type of surface created by the Fill Surface tool. Options include Ruled Surface, Spline Surface, and Freeform Surface.

Step 6: Create the fill surface

Once you have defined your boundary curves and adjusted any necessary options, it’s time to create the fill surface. Click on OK to generate the surface.

Step 7: Verify and modify the fill surface (if needed)

After creating the fill surface, take a moment to verify if it meets your requirements. If any modifications are needed:

  • Select: Click on the fill surface to select it.
  • Edit: Use tools like Delete Face, Delete Hole, or Edit Feature to modify the fill surface as desired.
  • Tips:
    • If you need to adjust individual control points of the fill surface, use tools like Edit Control Points.
    • You can also apply various surfacing features like fillets or drafts to enhance your fill surface.

Congratulations! You have successfully filled a surface body in SolidWorks!
