If you have a reference image or a pattern then you may use Inkscape for designing such pattern. it will be good if you have and black and white image. This software converts image file to a vector file. you can download the software here, It's free
https://inkscape.org/en/download/

I think I may explain it better with an example-

  1. Step 1:

    I just downloaded this file to use as a reference for the design.

  2. Step 2:

    Now open the inkscape and drag the image file in to it.

  3. Step 3:

    Now just adjust the dimensions for your sketch.

  4. Step 4:

    Go to Path > Trace Bitmap. In the menu, select the brightness cutoff. you may adjust the threshold here. then just place ok and close the menu.

  5. Step 5:

    Now just drag the image outside. you may see there are two of the pics now. one which we just dragged out is vector image.

  6. Step 6:

    Delete the other image. adjust the vector image accordingly.

  7. Step 7:

    Now save file in dxf format. Don't change any setting in next dialog box. Just click ok and that's it

  8. Step 8:

    Open your 3d model in solidworks.

  9. Step 9:

    select a plane you want that sketch on and go to Insert > DXF/DWG and insert the saved vector file from its location.

  10. Step 10:

    Import it as a 2d sketch and click on finish.

  11. Step 11:

    You may see the sketch now. although it may require some scaling and moving.

  12. Step 12:

    after adjusting its size you may use any required feature you want to use like extrude boss up to a surface or extrude cut offset a surface etc.

  13. Step 13:

    That's it. you may watch this video to learn more about inkscape.
