Some lines need to curve, and in this section, we deal only with curves of various types. To get your curve right, you can click on the line and drag it around to get close to what you require and there are 'handles' that you can click and drag around until you get the right shape that you're looking for, or you can use exact degrees. |

This is a curve between 2 points. Place your cursor over the label of the point where you’d like your curve to start, click, place your cursor over the label of the end point and click. The label will turn green while your cursor is over it. |

|Click on the first and second node. You may now drag the handles around to make the curve more pleasing or use direction and angle formulas to get a more precise curve |

When the cursor is over the line, it gets a very fine black edge. When the cursor is over the handle point, the circle is 'fat' and you can drag the handle around until you have your desired position. |
|||
| |
|||
Once you have the curve in place, on the right side, you can change the properties of the line, among other things. |
|||
* Name: Name of the new node |
|||
* First point: Starting point of curve |
|||
''Note. This tool was redesigned in version 0.5.0. Since 0.5.0 you can control length and angle of 'handles' by formulas.'' |
|||
* Second point: Endpoint of curve |
|||
* First point handle - Lenght: You can define a fixed lenght or use formulas for adaptive / calculated values |
|||
===[[File:GC00002.jpg|50px]] Tool Segmenting a simple curve=== |
|||
* First point handle - Angle: You can define a fixed angle or use formulas for adaptive / calculated values |
|||
This tool will place a point at the position that you require. Click on the curve, enter your formula and click on 'Apply' to view or 'Ok' to accept. No matter how you move the handles, the curve will always intersect with this point and the point will move as you move the handles. |
|||
* Second point handle - Lenght: You can define a fixed lenght or use formulas for adaptive / calculated values |
|||
* Second point handle - Angle: You can define a fixed angle or use formulas for adaptive / calculated values |
|||
* Attributes: Specify the color, linetype and lineweight of the new node |
