Slanted line
274
To create a line segment at the specified angle to another segment, use the automenu option:
Line at angle
This kind of line is constructed similar to the perpendicular type, except that the
angle can be entered in the property window.
The icon in the property window helps quickly change the specified angle for
the complementary one based on 180 0 .
Line tangent to an arc and passing through arc end
This configuration is supported by the automenu option:
Tangent Line
First, select the tangency arc. An auxiliary line will be displayed in the screen, tangent to this arc. The line
will be snapped to the end of the arc nearest to the pointer at the time of arc selection. Move the pointer with
the rubberbanded node along the line and fix the second node position by clicking or by input into
property window.
Line tangent to a circle or arc
Tangent Line through point
With this option, select a circle or arc (other elements are disallowed from selection), to which the tangency
line is to be constructed. The selected element will be highlighted, and the arc will be extended by an
auxiliary circle. An auxiliary node will be rubberbanding along the circle. This will be the first node of the
line segment, defining the tangency point between the line and the circle. The line will be rubberbanding
between the node and the pointer. To complete the tangent line, fix the position of the second node outside
the circle.
The position of the second node can be defined arbitrarily by clicking (use
object snapping as appropriate), or select an existing node. Besides, one can use the
property window by specifying coordinates of the node or the length of the line or
else the angle to the horizontal of the radius pointing to the tangency point between
the line and arc.
The position of the first line node will be defined automatically.
