Descrizione

Il vincolo Blocca applica un vincolo Distanza orizzontale e un vincolo Distanza verticale ai vertici (punti) selezionati nello schizzo. Se viene selezionato un singolo vertice, i vincoli di distanza orizzontale e verticale si riferiscono al punto di origine dello schizzo. Se vengono selezionati due o più punti, verranno aggiunti i vincoli di distanza orizzontale e verticale per ogni coppia di punti. Non esiste un sistema automatico per modificare i valori dei vincoli, essi devono essere modificati manualmente.

Utilizzo

Continue mode

Selezionare uno o più vertici (punti) nello schizzo.
Premre il pulsante Blocca.
Per modificare i valori dei vincoli, fare doppio clic su un valore di vincolo nella vista 3D, oppure fare doppio clic sul vincolo stesso o fare clic con il tasto destro e selezionare Modifica valore nell'elenco dei Vincoli nella scheda Azioni.

Run-once mode

Select one or more points.
Invoke the tool as explained above.
Depending on the selection two or more constraints are added.

Notes

There is no automatic prompt to edit the constraint values. If required values can be edited manually.

-"Create a lock constraint on the selected item"
-==Description==
-This constraint tool attempts to <em>fully constrain</em> any selected item.
+<div class="mw-translate-fuzzy">
-NOTE: It is advised that this tool be exclusively used on points for the time-being:

+<div class="mw-translate-fuzzy">
-Owing to the fact that FreeCAD is still under development - this tool exhibits strange behaviour when it attempts to 'lock' anything other than a point. For example (as of V0.12 R4802), when locking a circle by its circumferential line rather than its centre <em>point</em>, a horizontal constraint and a vertical constraint appear in the constraints dialogue, but they are both of value zero and do not appear in the graphics window.

-==Operation==
-<ol>
+</div>
-<li>Firstly it is necessary to highlight an item you wish to constrain. For reasons alluded-to above it is wise to only highlight a <em>point</em>.<br/>
-[[File:LockConstraint1.png|256px]]</li>
-<li>
-Highlighting of a drawing item is achieved by moving the mouse over the item and clicking the left-mouse-button.
-A highlighted item will change colour to green.<br?>
-[[File:LockConstraint2.png|256px]]</li>
-<li>
-Once an item is highlighted, left-clicking on the <em>lock</em> constraint serves to lock the highlighted item in-place. This usually manifests as two constraints: a horizontal distance constraint from the drawing axis origin, and a vertical constraint from the drawing axis origin. These are set by default to the current co-ordinates of the point.<br/>
-[[File:LockConstraint3.png|256px]]</li>
-<li>
-The vertical and horizontal constraints forming the lock can be edited by double clicking on the appropriate constraint to be edited either in the drawing itself or in the Constraint tab of the Combo View pane. This will open a dialog box to edit the constraint. Clicking on the horizontal constraint component produces:<br/>
-[[File:LockConstraint4.png|256px]].</li>
-<li>Enter the desired value into the dialog box and click OK.<br/>
-[[File:LockConstraint5.png|256px]]</li>
-<li>The new value of the constraint is applied to the drawing.<br/>
-[[File:LockConstraint6.png|256px]]</li>
-<li>The vertical constraint may be similarly edited to constrain the point to the desired location.<br/>
