Procedure
Creating 3D geometry
The purpose of the PartDesign Workbench is to allow the user to create geometry in 3D space to fulfill a certain need. As such, it is equipped with tools to make use of sketches and convert them to 3D objects.
There are two basic features to achieve this: Pad and Revolution. Alongside their subtractive counterparts ( Pocket and Groove) they make up most of the common actions used by this workbench.
- Switch to the PartDesign Workbench
- Select the sketch that was created in the Sketcher tutorial
- Select Pad
- Set the distance to 5 mm
- Select Ok
Another way to create 3D geometry is with the Revolution tool.
- Create a sketch based on the image above
- Select Revolution
- Set the angle to 360°
Subtracting Features
We'll begin by creating a sketch with the shape we want to subtract.
- Select the top face of the Pad
- Select New sketch
- Select External Geometry
- Approach the edge of the pad. An arc should be highlighted
- Select the arc. An arc of a different color should appear in the sketch
- Create a circle centered on the same point as the arc and set its radius to 5 mm
Afterwards, we'll proceed to apply a Pocket feature.
- Select the sketch
- Select Pocket
- Set the distance to Through all
Pattern Features
We are now finished with the basic workflow for the Sketcher Module.
