You should seeThe 3D view shows a pale round stone held by four tall claws, seen from a little above. The head has small pink marks on it, its handles, and to its right the buttons on the model, words you can click. The title bar, the strip above File and Edit, begins my-one-claw. 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-one-claw.

WhereThe 3D view, the button that reads Level 1 of 3: main.

DoClick Level 1 of 3: main twice. After the first click it reads Level 2 of 3: more, and after the second Level 3 of 3: each claw.

You should seeThe pink marks of the head go, and a small ring stands on the tip of each of the four claws. The button reads “Level 3 of 3: each claw”. Level 1 holds the main marks, Level 2 every number of the head, and Level 3 each claw on its own.

It worked whenThe button reads “Level 3 of 3: each claw”, and a ring stands on each claw’s tip.

If it goes wrongThe marks you used before, Over the table and the rest, are gone: Level 3 shows only each claw’s own marks. Click the level button once more: it goes back to Level 1.

WhereThe 3D view, a ring on the tip of a claw.

DoClick the ring itself, the small circle on the tip of one claw.

You should seeThree things appear for that claw alone, beside it: a curved mark, This claw: turn, and a short bar, This claw: width. Two new buttons stand on the model, This claw: profile and Reset this claw.

It worked whenThe buttons on the model include This claw: profile and Reset this claw.

WhereThe 3D view, the curved mark on the picked claw. Press and drag as in Drag a number on the model (P4-02), step 4.

DoRest the pointer on the curved mark until its label reads “This claw: turn”. Press on it, drag a little way round the stone, and let go.

You should seeThe claw turns about the stone’s axis, and only that claw. The label gives your number of degrees (the picture’s reads “This claw: turn 8.0 degrees default 0”). A drag gives your own number, not the picture’s.

It worked whenThe picked claw has moved off its place, and its three neighbours have not.

If it goes wrongAnother number changed: you pressed on another handle: press Ctrl+Z once, as in P4-02, step 5, rest the pointer first, read the label, and try again.

WhereThe sidebar: the CAD/CAM tab, the Setting section, the Head Builder panel. Press N with the pointer over the 3D view if the sidebar is shut. Scroll the sidebar so that the top of the panel shows, under its list of heads.

DoLook for the line that counts the changed claws, under the three level buttons.

You should seeA line “1 claw change”, with the button Reset all claws beside it. The panel counts how many claws have a number of their own: the claw you turned is one. The line above, “A set of 1 head”, counts heads and not claws: this panel is changing one head.

It worked whenThe panel reads “1 claw change”.

WhereThe 3D view, the short bar on the picked claw. Press and drag as in Drag a number on the model (P4-02), step 4.

DoRest the pointer on the bar until its label reads “This claw: width”. Press on it, drag a little way, and let go.

You should seeThe claw is wider than its neighbours, and they are as they were. The label gives your width (the picture’s reads “This claw: width 1.75 mm default 1.15”). A drag gives your own number, not the picture’s.

It worked whenThe picked claw is wider than its neighbours, which stay at 1.15 mm. Yours will differ from the picture’s 1.75 mm. A claw this wide is a drill, not a head to cast.

If it goes wrongAnother number changed: you pressed on another handle: press Ctrl+Z once, as in P4-02, step 5, rest the pointer first, read the label, and try again.

WhereThe 3D view, the button This claw: profile, one of the buttons on the model.

DoClick This claw: profile.

You should seeA small menu opens, headed “This claw’s profile”, and lists the claws’ profiles: Same as the set, Round claw, Oval claw, Rounded square claw and V claw. A profile is the shape of a claw cut through.

It worked whenA menu headed “This claw’s profile” stands open.

WhereThe menu that stands open.

DoClick Oval claw. Then, to see the claw from above, click the blue Z ball on the small coloured axes at the top right of the 3D view.

You should seeThe picked claw has an oval section, wider than it is deep, where the others are round. Seen from above, one claw is turned, wider and oval; the other three are round and stand as they were. The picture marks the claw you changed.

It worked whenThe picked claw is oval from above, and the others are round.

WhereThe 3D view: the rings are back on the tips. Click the ring of another claw. Press and drag as in Drag a number on the model (P4-02), step 4.

DoClick the ring of a second claw, then drag its This claw: turn mark a little way.

You should seeTwo claws now differ from the set’s, and the panel’s line reads “2 claw changes”. Each claw keeps its own numbers.

It worked whenThe panel’s line reads “2 claw changes”.

WhereThe 3D view, the buttons on the model, the button Reset this claw.

DoClick Reset this claw while the second claw is still picked.

You should seeThe second claw goes back to its place at once, and the first claw keeps its three changes. The panel’s line reads “1 claw change” again.

It worked whenThe panel reads “1 claw change”, and the first claw is still different.

WhereThe sidebar, the Head Builder panel, the button Reset all claws beside the count of changes.

DoClick Reset all claws.

You should seeEvery claw is the set’s again. The line “1 claw change” and its button are gone from the panel, and the buttons on the model have lost Reset this claw. The same button, Reset all claws, also stands among the buttons on the model while a claw has a change.

It worked whenThe line “1 claw change” is gone from the panel.

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-one-claw and carries no asterisk.
