What you will make
A Round 4.00, a round stone 4.00 mm across, on a small plate, in a quick rub-over bezel made with the older Bezels tool. Its top edge, the lip (the part pushed over the stone, as P5-01 says), stands 0.25 mm above the girdle and rolls 0.15 mm in over it, a fine rim over the stone’s crown, the part above the girdle: the way a rub-over looks once the setter has finished. That is the one thing this tool does that Stone Settings does not. At this size the rim is too fine to see, so the ring will look plain: judge the tool by its numbers, not by the picture. It is not what a production file holds: the bench’s rule is that no lip is formed over the crown in a file that goes out, because the setter pushes the wall over the stone at the bench. Stone Settings (Set several stones in rub-over with one button, P5-01) makes the straight wall that a caster takes. Skip this page if you only make for a caster.
About 5 minutes.
Files
- p5-03-start.blend (103 KB): open this one to begin.
- p5-03-finished.blend (109 KB): the result, to compare with yours.
Both were made in Blender 5.2.0.
Before you start
- You have done Part 0, Blender from nothing, and Shape a bezel’s section and make it real (P5-02): a bezel, a wall and a lip (the top edge pushed over the stone) are explained there and not again here. The Lip of this older tool is the same idea as the Over the girdle of Stone Settings, with a roll over the crown added.
- CAD/CAM Jeweller 2.22.0 or later (Preferences > Add-ons shows the version). The start file holds a Round 4.00 standing on a plate 12 x 8 x 1.5, in millimetres.
- Small pink dots, arrows and squares, and the word Done, may show on a stone once it is selected. They are handles: marks that change a number when you press and drag them. Leave them alone for now: click the stone’s grey top, between the marks. If a number changes after a click, a mark was pressed: press
Esc, thenCtrl+Z.
Build it
Step 1. Open the start file and save your copy
WhereThe top bar: the row of words that begins File, Edit.
DoDownload p5-03-start.blend from Files above and open it. Then choose File > Save As and save it under the name below, in a folder of yours. Open an exercise file and keep the start file safe (P0-07) shows how.
Typemy-quick-bezel.blend
You should seeThe 3D view shows a round stone standing on a small plate, with nothing selected. The title bar, the strip above File and Edit, begins my-quick-bezel. The first picture is the 3D view and the second is the title bar.
It worked whenThe title bar, the strip above File and Edit, begins my-quick-bezel.
Step 2. Press Apply Rub-over Preset
WhereThe sidebar: press N with the pointer over the 3D view if it is shut. Click the CAD/CAM tab, then Setting in the section bar. Fold the long panel Stone Settings by clicking its title once, so that it shuts up to its title. Then scroll down (two fingers on a touchpad) to the panel More Settings, and its box Rub-over.
DoPress Apply Rub-over Preset.
You should seeNothing moves in the 3D view: the button fills in the numbers of the Bezels panel for a quick rub-over of a 4 mm round stone. It says so in the box: wall 0.40, lip 0.25 and a roll of 0.15 are the add-on’s own starting figures for it. A lip is the top edge of the bezel, the part rolled over the stone.
It worked whenThe button was pressed with no error, and the next step finds the new numbers in Bezels.
Step 3. Read the Bezels panel
WhereThe sidebar, the Setting section: the panel Bezels, a few lines above More Settings. It is shut: click its title to open it.
DoClick the title Bezels, a few lines above More Settings, and read Wall and Lip.
You should seeA picture of the kind of bezel, and the numbers the preset set: Wall 0.4 mm and Lip 0.25 mm. Under the numbers a short line warns that the wall is under the add-on’s own 0.50 mm (“Bezel wall 0.40 mm is under the 0.50 mm house default”, the add-on’s starting number). The warning stays. A wall of 0.40 is under this tool’s 0.50, under the bench’s own 0.55 for a bezel and under the 0.60 least for structural metal: it is a picture wall, for looking at only, and not a figure to cast.
It worked whenWall reads 0.4 mm and Lip reads 0.25 mm.
Step 4. Click the stone and press Make Bezel
WhereThe 3D view, the stone’s table, the flat top. Then the Bezels panel, the button Make Bezel.
DoClick the stone, then press Make Bezel.
You should seeA ring of metal stands round the stone, and the status bar says “1 bezel built”. The top edge is rolled in 0.15 mm over the girdle: a rim too fine to see at this zoom, so the bezel reads as a plain ring, and you judge it by its numbers. The status bar line fades after a moment, as the third picture shows it; the Outliner, the list at the top right of the window, keeps the new row (its name is cut short in the narrow list). The tool gives no verdict on whether the figures are good: it only builds from the numbers in the panel.
It worked whenA bezel stands round the stone, and the Outliner lists CJ_Bezel_Round_4.00x4.00.
Step 5. Press Select Bezels
WhereThe Bezels panel: the button Select Bezels, beside Delete Bezels under Make Bezel.
DoPress Select Bezels.
You should seeThe stone is no longer selected and the bezel is, with an orange outline. Select Bezels selects the bezels of the selected stones, or every bezel in the file when no stone is selected. The words at the top left of the 3D view name the bezel.
It worked whenThe words at the top left of the 3D view name CJ_Bezel_Round_4.00x4.00.
Step 6. Press Delete Bezels
WhereThe Bezels panel: the button Delete Bezels.
DoPress Delete Bezels.
You should seeThe bezel goes and the stone and the plate stay, as in the start file. With no stone selected, Delete Bezels removes every bezel of the older tool in the file. A bezel from Stone Settings is not one of them: it has its own row and its own bin (P5-01).
It worked whenThe stone stands on the plate with no bezel round it.
Step 7. Save your work
WhereThe 3D view: move the pointer over it.
DoPress Ctrl+S.
You should seeBlender writes your copy at once, with no question, because the file already has a name. An asterisk, *, in the title bar marks changes that are not saved, and it goes now. Save your work and get it back (P0-12) says more about saving.
It worked whenThe title bar begins my-quick-bezel and carries no asterisk.
No picture: the only change is a message on the status bar, and it fades.
Check your result
| What to read | Where | What it should say |
|---|---|---|
| The preset | The Bezels panel, Setting section, at step 3 | Wall reads 0.4 mm and Lip 0.25 mm |
| The bezel | The Outliner, the list at the top right, after step 4 | One new object, CJ_Bezel_Round_4.00x4.00 |
| After Delete Bezels | The Outliner, after step 6 | The bezel is gone and the Round 4.00 and the plate stay: 2 objects in all |
Try it yourself
Open your copy, press Apply Rub-over Preset again, then raise Lip to 0.50 in the Bezels panel before you press Make Bezel. Read the line under the numbers before you press it. Then press Delete Bezels to clear it.
What you learned
- Apply Rub-over Preset fills the Bezels panel with a quick rub-over’s numbers, and Make Bezel builds it round the selected stone.
- The older tool rolls its lip over the crown, though at 0.15 mm you judge it by its numbers. That is for a picture. A production file uses a straight wall from Stone Settings, and the setter pushes the top over the stone at the bench.
- Select Bezels and Delete Bezels take every bezel of the older tool in or out of the file. The next page, Drag a setting’s numbers on the metal (P5-04), moves a live setting’s numbers by hand.
