Atelierul TechDraw (Desen Tehnic)
Introducere
Tehnologia TechDraw Workbench este utilizată pentru a produce desene tehnice de bază de la modele 3D create cu un alt atelier de lucru, cum ar fi Part, PartDesign, sau Arch,sau importate din alte aplicații. Fiecare desen este o pagină care poate conține diferite Vizualizări ale obiectelor trasabile cum ar fi Part::Features, PartDesign::Bodies, App::Part groups, și Document Object groups. Desenele rezultate pot fi folosite pentru lucruri precum documentație, instrucțiunile de fabricație, contracte, permise etc.
La pagină pot fi adăugate simboluri, secțiuni, suprafețe hașurate, adnotări și simboluri SVG, care pot fi exportate în continuare în diferite formate ca DXF, SVG și PDF.
FreeCAD este în primul rând o aplicație de modelare 3D și, prin urmare, nu are multe instrumente de desenare 2D, care sunt incluse în cea mai mare parte în Draft și Sketcher Workbench. Dacă obiectivul dvs. principal constă în realizarea de desene complexe 2D și DXF și nu aveți nevoie de modelare 3D, vă recomandăm să luați în considerare un program software dedicat pentru redactarea tehnică, cum ar fi [https: //en.wikipedia .org / wiki / LibreCAD LibreCAD], QCad, TurboCad și altele.
Snapping
introduced in version 1.0: The TechDraw Workbench has a snapping feature. It can be used to automatically align views, section views and dimensions when positioning them by dragging with the mouse. With Snap View Alignment enabled (default) in the preferences, views will snap to alignment with other views when close enough (View Snapping Factor setting). Dimensions are also snapped to other parallel dimensions and the dimension text can be snapped to the middle of the dimension line. Snapping can be temporarily disabled by holding down the Alt key.
