Step 5: Extrude Cover Body
Now the Sketch will be turned into a body.
Instead of extruding a fixed distance, we’ll extrude relative to existing geometry.
(We extrude the shape far enough to cover the LED Ring without needing to know its thickness)
- Check again that the Front Cover component is active.
(Yes, check again. It is a good habit)
- Select the Extrude tool, (press e)
- Click on and highlight every profile in the sketch except for the slice under the line.
- In the tool dialog, change ‘Extent‘ to To Object.
- Show the LED Ring component, (By clicking on its icon)
and zoom in far enough to see the fine details.
- Hover over one of the LED Ring LED corners until a dot appears,
Click on it to mark the extrude distance.
- The cover needs to be a little bit deeper than the ring,
In the tool dialog, set ‘Offset‘ to -0.4 mm.
(If it doesn’t cover the LEDs, try making the offset positive 0.4mm)
- Click OK – first feature done!
- The LEDs are sticking through the front of the cover!
When using Extrude To and Offset, it’s possible that the +/- sign of the offset distance might need be reversed.
Go back and Edit the Extrude feature (Find it in the timeline, right-click, ‘Edit Feature’) and change the sign of the Offset distance.
- The LED ring moved, and now it looks strange!
The joint for the LED ring might not be created properly.
Check your timeline – do you have all four joints? Are there any things coloured yellow?
If there aren’t four joints; roll back the timeline to before the new component, go back to tutorial #3 and see if you can figure out which ones are missing.
If the joints are yellow, right-click on them and select ‘Edit Joint‘, and try clearing the components and re-defining them.
