After rotate UCS

<p>I use the following commands:</p><p>UCS</p><p>Z</p><p>60</p><p>to rotate the coordinate about Z axis for 60 degree.. </p><p>After that, How could I get the number I rotated?</p><p></p><p>I have a&nbsp;drawing of which the ucs is not at the origin. There is an angle. I want to get the angle and rotate it back to normal position.</p><p></p><p>Thanks.</p><p></p>

<p>UCS→p&nbsp;&nbsp;&nbsp; Rotate back the UCS angle</p><p>UCS→n→indicate the origin position you want</p>

<p>我主要关心的是角度。</p><p>比如原图坐标系相对于普通的直角坐标系旋转了42.732度。我打开这个图后怎样得到这个角度值，以便转回到直的坐标。</p>

<p>没明白。</p><p>转了后画两条线相互垂直的线。用list看什么呀？根据什么转回来？</p>

<p>Angle in X Y plane→UCS rotate angle</p>

<p>没太大帮助。</p><p>在倾斜的坐标系下任意画条线不行。打开正交再画，list后角度是0或者90。只能根据坐标自己计算了。</p>
