In professional CAD software like SOLIDWORKS or Autodesk Fusion , you can apply drafts using these common methods:
Before finalizing a design, you can use a Draft Analysis tool to color-code faces based on their slope. This helps identify "undercut" regions that would be impossible to eject from a mold. Design Best Practices How to use the Draft Feature in Fusion 360! kk1.zip
This method allows you to apply a taper starting from a specific split line on the model, often used for more complex geometries. In professional CAD software like SOLIDWORKS or Autodesk
You select a plane or face that remains stationary, and the draft angle is measured from it. kk1.zip
