Descriere
Comanda șterge elemente neutilizate în geometria internă sau recreează elementele lipsă.
The command deletes unused elements aligned to internal geometry, or recreates the missing ones.
Utilizare
- Selectați un element al unei schițe care acceptă alinierea internă (în prezent, doar Elipsa / Arc).
- Apelați comanda făcând clic pe un buton de pe bara de instrumente, selectând elementul de meniu sau utilizând comanda rapidă de la tastatură.
Dacă există sloturi de aliniere libere pentru elementul selectat, se creează o nouă geometrie a construcției și se aliniază cu sloturile disponibile. Dacă toate locațiile de aliniere sunt ocupate, geometria internă neutilizată este ștearsă (elementul este tratat ca nefolosit dacă nu este forțat să facă altceva).
- Select an element of a sketch that supports internal alignment (currently only Ellipse/Arc and B-spline).
- Invoke the command by clicking a toolbar button, picking the menu item or using the keyboard shortcut.
If there are free alignment places for the selected element, new construction geometry is created and aligned to the available places. If all alignment places are occupied, the unused internal geometry is deleted (the element is treated as unused if it is not constrained to anything else).
Exemplu
Creați o nouă elipsă. Noi elipse sunt întotdeauna complet ambalate. Veți vedea o elipsă și o grămadă de geometrie a construcției: diametru major, diametru minor, focare.
Create a new ellipse. New ellipses are always fully-packed. You'll see an ellipse and a bunch of construction geometry: major diameter, minor diameter, foci.
Selectați linia axei minore și click pe DEL. Axa minoră dispare, dar elipsa rămâne. Cum facem să aducem linia axei minore înapoi?
Selectați elipsa și apelați comanda Sketcher_RestoreInternalAlignmentGeometry. Axa/diamtrul minor este reafișat.
Acum, constrângeți axa/diametrul major al elipsei la o anumită lungime. Selectați elipsa și apelați comanda Sketcher_RestoreInternalAlignmentGeometry. Diametrul minor și focarele sunt șterse, însă diametrul major este păstrat, deoarece participă la alte constrângeri. Centrul Elipsei rămâne și el, deoarece este un atribut integrat(inerent), ca un centru al unui cerc.
