Rotating Viewports

There must be an easier way than the way I'm doing it

When I want to rotate a veiwport I

mvsetup

align

rotate

then I play with angles until it looks about right

The trouble is the angle is absolute. Rotating 90 is easy but sometimes I play with it until it ends up as 53.7 deg

I then make a copy for another drawing but want to rotate it 5deg different from the 53.7 deg

At the moment, I do the math but there must be an easier way

double click inside the viewport & us 'ucs>n>3point' option

and once done don't forget to save it with name so that you can restore it back anytime.

also lock the viewport

There are several ways to do it.

I try to avoid the math so what I do is make a line that follows my desired x axis. Then UCS > Object and select that line. Then PLAN > Current UCS. Usually I will return the UCS to World when I am done.

DVIEW > TWist is another method...

As is 3dOrbit (I find using this method very easy)

UCSFOLLOW will work..

type UCSFOLLOW and set it to 1.

Go to the viewport and align the UCS to the line. (The view in the viewport will now be in line.)

type UCSFOLLOW and set it to 0. Thats it..

Unfortunately

I can only do it through mvsetup as I cannot adjust the ucs

Adjusting the UCS would only be temporary, just toggle to UCSworld after you have rotated the viewport to reset the coordinates to its original state

As is 3dOrbit (I find using this method very easy)

but this method doesnt rotate a viewport with a precise angle of rotation

DVIEW > TWist doesn't change the UCS.
