Cutting Assistant: Overview
Cutting Assistant guides you through the cutting sequence — tier by tier, facet by facet — once you're at the lapidary machine with your rough and cutting head ready.
What is the cutting sequence?
A faceting design like Round Brilliant has 57 facets organized into 6 tiers. You can't cut them all at once — you cut in a specific order:
- Girdle first: Set the blank size and the outline edge.
- Pavilion: Cut the bottom tiers from steep to shallow.
- Crown: Cut the top tiers from shallow to steep (or in another order depending on your machine's geometry).
- Final polish: Each facet gets a final light pass to remove any scratches.
The sequence matters because:
- The girdle sets the stage — everything else is cut relative to it.
- Pavilion mains determine pavilion depth.
- Pavilion breaks and the culet fill in below the mains.
- Crown mains sit above the girdle.
- Crown breaks fill in toward the table.
Cut out of order, and you'll have geometry conflicts or wasted effort.
The Cutting Assistant tool
Cutting Assistant walks you through this sequence:
- Shows you the current tier: angle, distance, cone angle, how many facets, how many copies you've cut so far.
- Walks you through each facet in the tier so you don't lose track.
- Lets you mark facets as done as you cut them.
- Calculates progress (how many facets remain).
It's a checklist + timer, letting you focus on the actual cutting instead of juggling notes.
How to use it
Open Cutting Assistant when:
- You've loaded your design into the Developer and confirmed the angles.
- You've exported the PDF or loaded the
.facetfile into your machine control software. - You're about to start cutting at the lapidary machine.
Click through each tier, mark facets as you go, and Cutting Assistant keeps you on track.
