Sa se deseneze chenarul unui format A3 si indicatorul, pentru realizarea unui desen de executie al unei piese


Sa se deseneze chenarul unui format A3 si indicatorul, pentru realizarea unui desen de executie al unei piese.

Se deschide o sesiune de lucru AutoCAD; si din fereastra Mechanical Desktop Power Pack Today se selecteaza optiunea Create Drawings si de aici suboptiunea Metric.

Se stabilesc limitele desenului cu comanda LIMITS:

Command: Limits

Reset Model space limits:

Specify lower left corner or [ON/OFF] <0.00,0.00>: enter



Specify upper right corner <420.00,297.00>: enter

Se traseaza chenarul formatului A3 cu comanda LINE.

Command: Line

Specify first point: 0,0

Specify next point or [Undo]: 420,0

Specify next point or [Undo]: 420,297

Specify next point or [Undo]: 0,297

Specify next point or [Undo]: c

Command: Pline

Specify start point: 10,10

Current line-width is 0.00

Specify next point or [Arc/Halfwidth/Length/Undo/Width]: w

Command: Line

Specify first point: 20,10

Specify next point or [Undo]: 20,287

Specify next point or [Undo]: enter (esc)

Se incepe desenarea indicatorului. Prima data se deseneaza conturul exterior al acestuia. Dimensiunile de gabarit ale indicatorului sunt: lungime = 180 si inaltime = 40.

Command: Line

Specify first point: 230,10

Specify next point or [Undo]: 230,50

Specify next point or [Undo]: 410,50

Specify next point or [Undo]: enter
