Locks the next point will be placed at a specified angle relative to the last point.
To constrain to an angle
4 Type an angle at the command prompt in the format <angle and press Enter.
The cursor moves along a line at the specified angle.
NO IT DOESNT. well not for me anyway.
I select line tool, click start point, then type <47.457 and hit enter, draw the line in a north west direction which appears at that sort of angle (as rhino 0 is north) yet measure it afterwards at it isnt !.
have I overlooked something ?
it also will draw two other lines near vert and near horiz neither of which are 47.457 on anything. Angle constraint fail.3dm (31.0 KB)
In a two-dimensional Cartesian coordinate system, an angle is typically defined by its two sides, with its vertex at the origin. The initial side is on the positive x-axis, while the other side or terminal side is defined by the measure from the initial side in radians, degrees, or turns. With positive angles representing rotations toward the positive y-axis and negative angles representing rotations toward the negative y-axis. When Cartesian coordinates are represented by standard position, defined by the x-axis rightward and the y-axis upward, positive rotations are anticlockwise and negative rotations are clockwise.
