Add Fixed Line Angle

 Edit Bar controls: Apply angle from horizontal axis, Small angle


This tool is used to apply a fixed angle between two lines.


Apply angle from horizontal axis - If this option is switched on only one line needs to be identified as the first line is assumed to be the horizontal axis.


Small angle - If this option is switched on the smaller of the two possible angles is used.


To use the tool, depending on the edit bar options, identify either a single line or a pair of lines followed by the sector between the lines to define the angle. This will bring up the Fixed Value form:



At this point, you can either enter a numeric value or a variable, such as =ANG, in which case the Variable Properties form will be opened:



Here, you can enter a suitable Prompt and a value or an Expression.


Once the constraint has been added, the angle between the lines cannot be altered.
