We often receive questions about modeling the hole chamfers on the TITAN Academy parts, so this guide explains a dependable method that works across most CAD software, including Fusion 360, SOLIDWORKS, and similar CAD platforms.
Most CAD programs include a Chamfer tool, and in many situations it works well. However, depending on the geometry, face type, or feature order in the model, the chamfer tool may not always produce the correct result. In those cases, a simple sketch and extrude cut method provides a reliable solution that works in nearly any CAD system.
This method works for the TITAN-1M through TITAN-5M parts.
To model the required hole chamfers on any of the TITAN Academy parts:
Create a sketch on the top face of the part.
Sketch circles centered on the holes using the chamfer diameter shown on the print.
Use an Extrude Cut (or equivalent feature in your CAD software).
Set the cut distance to -.055 in with a 45° taper angle.
This operation produces the correct chamfer geometry on the holes and fully models the feature.
As always, take another careful look at the print and confirm that your model matches the required dimensions and geometry. The print is the source of truth.
Hope this helps everyone continue to DESIGN TO GREATNESS.
