Learn how to trace a reference image into Blender to create a basic 3D printable model using the add on CAD Sketcher. We fully explain the process from a beginner perspective to keep it as easy as possible. Learn how to:

* Import a reference image.
* Scale the image to the correct size.
* Model to scale.
* Trace the image into a mesh using the 2D geometry.
* Extrude the 2D geometry into 3D.
* How to use constraints such as diameter, distance, tangent, coincident and mid point.
* Utilise construction geometry.
* Problem solve redundant constraints.
* Create a fully defined sketch.
* Use solidify modifiers.
