how to draw a perpendicular bisector.

[Pedi]

Hi

I'm new to Autocad and have problem drawing a perpendicular bisector .

I have an oblique line and want to draw its perpendicular bisector .

Is there an easy way to do that?

I'll really appreciate it if you could help me .

thanks a lot

I will draw a line from an arbitrary point perpendicular (OSNAP mode Perpendicular) to that line and move it later to the middle (OSNAP mode Middle) of the line.

And I would turn on Polar Tracking, start the line command, pick the mid point and the Polar tracking would show me where the perpendicular was.

@eldon: Please tell me, is there a way to use the Polar tracking solution if the target line isn’t the last added item in drawing?

I have my Polar Tracking set to Relative to last segment, and when you pick on the Midpoint of a line, it aligns itself to the line you have just picked, whenever it was drawn

Thank you for explanation. I think I missed something in my first try since it looked to work only on the last added segment. But work as expected now; so, have learned something new today. Thanks!

Copy and past the line, then rotate it 90 degrees, then move it to the midpoint of the original line.

I use the tracking method usually, but another quick method to do this is to use _ROTATE, select the midpoint and then C for the Copy option and 90°.
