To specify angular co-ordinates
Angular co-ordinates are defined by specifying:
The distance along a chosen rotary axis
The distance along one other axis
An absolute angle of rotation around the rotary axis.
Enter co-ordinate data as follows:
Select the Rotary Axis.
Type your required distances along the A, B and C axes into the X, Y and Z boxes respectively. This is done in the way described for Cartesian co-ordinates.
Enter the absolute angle (degrees) into the Angle box.
Select the OK or Continue buttons when you have completed your co-ordinate specification.
Specifying Angular Co-ordinates in Command Format
Experienced users can enter co-ordinates directly though the Command box. You can also display this box by pressing one of the keys that corresponds to an axis or a command (for example, X, Y, Z, A, B, C, I, W, R, P).
Angular co-ordinates are specified by entering a distance along a rotational axis, a distance along one other axis and then an angle of rotation, for example
X50Y50A90 should give a point at X50 Y0 Z50 because the point defined at X50Y50 is rotated by 90 degrees about the X (A) axis.
