Find Rotation Angle of the current View

arcticad — Fri, 03 Feb 2012 17:52:11 GMT

I'm looking to find the current rotation of my view in modelspace.

This isn't the ucs directionm but any arbitrary view i'm using.

For example using 3dorbit to rotate around an object.

I want to match some temp graphics to align flat to my view.

EDIT:

I see there is a VIEWDIR variable. so that may be what I need

Just a shot in the dark

GetSystemVariable("ucsxdir") maybe

~'J'~

ucsxdir gives me the angle of the ucs and not the angle of the view as I am currently looking at it.

Thank You for the effort. It's appreciated.

Can you give a code sample on how to access it. I'm not finding any examples.

Can you share a better link? I can't find a lesson 8.

Thanks.

nobody here actually answered the question. They left little links for you to go and get it yourself, little frustrating.

Type "snapang" + enter and it'll display the current 2D view rotation. I can only answer for 2D at the moment.

The only thing frustrating here is that the question was answered and that You probably aren't able to recognize it, because you don't realize that this is a programming-related discussion group.

This is not an answer. This question asked ~4 years ago was about how to find the rotation angle of the current view in program code, not by issuing commands.

This has worked for me.

1. UCS; View

2. Draw a random horizontal line in ortho mode.

3. UCS; World

4. List line rotation or set new UCS to line and save UCS (UCS; Save)

This discussion group is focused on programming.

The question was asked in the context of how to find out the rotation angle of the view in code, not interactively using commands,

However, the steps you outline for finding the answer interactively is the scenic route.

Command: VIEWTWIST VIEWTWIST = 45 (read only)
