Knurl

Knurl gives a round face a grip: straight grooves along the axis, or a diamond pattern of grooves both ways round. A cosmetic knurl is drawn on the face and costs nothing to rebuild; a modeled knurl cuts the grooves.

Access: Toolbar > Knurl.

Steps

1. Click Knurl.
2. Click the outside of the round faces to knurl.
3. Choose Straight or Diamond and set the pitch, angle, depth and profile.
4. Turn on Modeled to cut the grooves.
5. Click OK.

Options

Option	Description
Pattern	Straight: grooves along the axis. Diamond: grooves both ways round, crossing
Pitch	Groove to groove around the face; the number of grooves is the circumference over the pitch
Angle	Diamond: the grooves' angle to the axis, 30 deg by default
Depth	How deep the grooves are
Profile	The V of a groove, 90 deg by default
Modeled	Cut the grooves. Off: lines on the face

Tips

• A modeled knurl makes many faces. Above 2000 faces Moket warns (KNURL_HEAVY): use a coarser pitch, or keep the knurl cosmetic until you need the geometry.
• Common pitches are 0.5 to 1.2 mm; the depth is about a third of the pitch.
