Up is 0 degrees?

[bobsy852]

I'm new to this forum but have been looking at it for a while for help so decided to register when i could not find my latest answer in the hope someone can help!

It's probably something stupidly simple, but I can't find out how to change it!

As I was aware, and I'm sure I remember it used to work like this on my CAD, a horizontal line from left to right was 0degrees!

However, somehow I seem to have changed this, so that this now registers as 90degrees on CAD and a vertical line up is 0degrees?

 

Anyone know what I've done and how to change it back?

 

Thanks for the help!

Check if your UCS (user coordinates system) isn't rotated. To fix it, call UCS command and press (to accept default option, reset UCS to WCS).

Thanks for the reply, just tried that, it still thinks horizontal is 90degrees!

In this case check the value of ANGBASE system variable - should be set to 0.0.

thank you Msasu!! Work's like it should again!

No idea how I changed that but glad it's working properly again now! Should make drawing these angles a lot easier!

Thanks again!

You welcome!

This can be changed also by Units -> Direction...

I say it's working, east has now been restored to 0degrees, however, no South is 90degrees and North is 270degrees?

Shouldnt these be the other way around?

Please verify under Units dialog box the state of "Clockwise" toggle; should not be checked (to get angles trigonometrically).

Wait, don't worry! I've solved that little problem! The "clockwise" was ticked in that Units dialog box!

Thanks for helping me restore angular normality Msasu!

Check ANGDIR system variable. It should be set to 0 for normal AutoCAD angle working.

Sound good! You welcome!
