Draft angle feature in Solidworks - Step-by-Step Guide

Choose your learning style9 modes available
Introduction
The draft angle feature in SolidWorks helps you add a slight angle to faces of a 3D model. This makes it easier to remove parts from molds in manufacturing. It solves the problem of parts sticking in molds by creating tapered surfaces.
When designing plastic parts that will be molded and need to release easily from the mold
When creating metal castings that require tapered sides for easy removal
When adding a slight angle to vertical faces to improve the look or function of a part
When preparing a model for manufacturing processes that need draft angles
When adjusting existing parts to meet manufacturing requirements without redesigning
Steps
Step 1: Open the part file
- SolidWorks main window
The 3D model appears on the screen
Step 2: Click
- Features tab > Draft tool
Draft PropertyManager opens on the left side
Step 3: Select
- Faces to draft in the graphics area
Selected faces highlight in yellow
Step 4: Choose
- Neutral plane or face in the Draft PropertyManager
Neutral plane highlights and draft direction sets
Step 5: Enter
- Draft angle input box
Faces preview shows the angled draft applied
Step 6: Click
- OK button in Draft PropertyManager
Draft angle feature is added to the model
Before vs After
Before
The vertical faces of the part are straight with no angle
After
The selected faces have a 5-degree angle taper away from the neutral plane
Settings Reference
Draft angle
📍 Draft PropertyManager > Angle input box
Sets how much the face will be angled from the neutral plane
Default: 0 degrees
Neutral plane
📍 Draft PropertyManager > Neutral plane selector
Defines the base face or plane from which the draft angle is measured
Default: None
Faces to draft
📍 Draft PropertyManager > Faces selection box
Specifies which faces will receive the draft angle
Default: None
Common Mistakes
Selecting the wrong neutral plane
The draft angle will be applied in the wrong direction, causing manufacturing issues
Always select the face or plane that represents the base or mold opening direction
Entering a zero or very small draft angle
No effective draft is created, so parts may stick in molds
Use a draft angle of at least 1-2 degrees depending on the material and process
Summary
The draft angle feature adds a tapered angle to faces for easier mold release.
You must select the correct neutral plane to control draft direction.
Set a meaningful draft angle to ensure manufacturability.
