Link Line
Steps
1.Click Link Line 
button in the Vector Editor, LineHookModel pop-up window will appear. Select the corresponding mode to perform the link operation and see the detailed description below for details.
The pop-up window selects the connection mode and the relative relationship of the lines
Parameter Description
- LineHook: According to the spatial geometric relationship of the two lines, they are connected end to end or extended to intersect.
- ArcHook: According to the spatial geometric relationship of the two lines, the end points of the two lines plus a user-defined point are selected, a total of three points are used to determine a circular arc; or a point is selected by user-defined and connect the two lines in a circular arc tangent to the two lines.
2.LineHook
(1)Intersect: Select LineHook, and the relative relationship of the lines is intersect, click the left mouse button one by one, and select the two lines that need to be linked to complete the automatic linking. Among them, the order of clicking must be consistent with the direction of the line. As shown in the figure below, you need to first click line 1 and then click line 2 to achieve the desired effect.
Note: Intersect means that the straight lines passing through two line segments can intersect at one point.

(2) collineation:Select LineHook, and the relative relationship between the lines is collineation, click the left mouse button one by one, and select the two lines that need to be connected to complete the automatic connection. Among them, the order of clicking must be consistent with the direction of the line. As shown in the figure below, you need to first click line 1 and then click line 2 to achieve the desired effect.
Note: Collineation means that the straight line passing through the two line segments is approximately on a straight line.

3.ArcHook
(1)Parallel: Select ArcHook, and the relative relationship of the lines is parallel, click the left mouse button in turn to select the two lines to be hooked, and the order of clicking must be consistent with the direction of the line, as shown in the figure below, you need to first click line 1 and then line 2 to achieve the desired effect. Finally right-click to select the key point of the arc to be generated, and the arc hook in parallel mode can be completed.
Note: Parallel means that two lines are approximately parallel in space.

(2)Intersect: Select ArcHook, and the relative relationship of the lines is intersect, click the left mouse button in turn to select the two lines to be hooked, and the order of clicking must be consistent with the direction of the line, as shown in the figure below, you need to first click line 1 and then line 2 to achieve the desired effect. Finally right-click to select the key point of the arc to be generated, and the arc hook in intersection mode can be completed.
Note: Intersect means that the straight lines passing through two line segments can intersect at one point.

(3)Collineation: Select ArcHook, and the relative relationship of the lines is collineation, click the left mouse button in turn, and select the two lines to be hooked. The order of clicking must be consistent with the direction of the line. As shown in the figure, you need to first click line 1 and then line 2 to achieve the desired effect. Finally right-click to select the key point of the arc to be generated, and the arc hook in collineation mode can be completed.
Note: Collineation means that the straight line passing through the two line segments is approximately on a straight line.
