Answers
Answer:
Step-by-step explanation:
How can you draw lines at a 90 degree angle in AutoCAD?
There are many methods to draw lines at 90 degree angle in AutoCAD:
1.Using POLAR CO-ORDINATES SYSTEM
command: LINE <enter>
start point: click on required location or specify the co-ordinates
Type 100,100<enter>
next point: Type @100<90 <enter>
The output of above command sequence is a line started location at co-ordinates (100,100) at of 100 length is drawn at angle of 90 degrees .
A LINE DRAWN AT 90 DEGREES
2.Using ORTHO mode
command: ORTHO <enter>
command: ON/OFF : Type ON <enter>
command: LINE <enter>
start point: click on required location or specify the co-ordinates (say ) 200,100<enter>
next point: Drag the mouse in vertical direction and Type 100 <enter>
A LINE DRAWN AT 90 DEGREES
3.Using POLAR TRACKING mode
command: POLAR <enter>
ON/OFF : Type ON <enter>
increment angle : Type 90 <enter>
command: LINE <enter>
start point: click on required location or specify the co-ordinates (say ) 300,100 <enter>
next point: Drag the mouse so that 90 degree is displayed in tooltip and Type 100 <enter>
A LINE DRAWN AT 90 DEGREES
Further by manipulating polar snapping , object snapping ,tracking both object and polar combining any of the mentioned any lines can be drawn at any angle
Also with command XLINE , or RAY also enable to draw angular lines to desired angles.
