Angled Fillet Tutorial

• To create a 1/4 inch rounded fillet between the box top and the angled cylinder the drawing is set up as shown.
• The 2 Light Blue boxes are placeholders for Cross Sections and Parallel Lines.
  • Boxes are 1/2 the radius of the fillet thick and surround the cylinder.

• Use the points shown to do Cross Sections.
  • ( Some intersections such as between grids and planes can use Surface Intersection instead, but Cross Section worked best here.)
  • Command: Solids->Cross Section
  • Select X-Z plane.
  • Gravity Snap at each Arrow and hit F3 to repeat the command.
  • This should give you the 3 lines around the cylinder as shown.
• IMPORTANT: Select each of the 3 lines and do Vector Convert on each one.

• Open a new 2D drawing and layout the angle of the cylinder to the box.
  • Fillet the lines to 1/4 inch and check the box: Leave original lines
  • Use Parallel by Distance to create a parallel line above the horizontal line1/2 the radius of the fillet.
  • Extend the line past the angled line with Extend
  • Select Dimension and Double click on Intersect Snap to set both dimension points.
  • This is the parallel offset for the middle cross section. (0.068)

• In Layers, click on Separate.
  • Determine layer of cylinder with Info Box and turn it off.
• Select Parallel by Distance and enter value 1/4.
  • Select lower Cross Section and then Gravity Snap to point at small Arrow.
    • This draws parallel on the plane of the box.

• Select Parallel by Distance and enter value determined from 2D drawing (in this case 0.068)
  • Select center Cross Section and then Gravity Snap at small Arrow

• Now you have the 3 lines for a Surface Connect.
  • Surface Connect them in the order shown setting points in approximately the same plane.
  • Hit Enter.

• Fillet should look like this.

• I selected the fillet and changed the color to Orange.
• Solid Shaded Phong and a second Light added with a higher vertical setting.
