After that, select a graphic line. The arc will originate in the end node of the
selected line nearest to the pointer position at the time of selection. In the
continuous input mode, the arc originates in the end node of the last created
element. The rubberbanding arc can be moved by the mouse to the desired
position and fixed. The position of such arc can be specified in exact values. To do
this, select a graphic line, and then specify the end point coordinates of the arc in
the property window. Alternatively, one can specify the radius (diameter) and the
arc angle. In the latter case, first use the mouse to specify the direction of the arc.
Arc tangent to another arc
Arc tangent to arc
This automenu option allows selecting an entity (a line segment, circle or arc), to
which the arc being created should be made tangent. The selected element will be
highlighted and projected (extended) up to the full line or circle. A rubberbanding
circle will appear on the screen, tangent to the selected element. The position and
the size of the circle change as the pointer moves.
The second step is constructing the end node away from the tangency entity, for
the arc being created to pass through. This node can be freely defined by placing
the pointer at the desired position, by watching the coordinates displayed in the
status bar , or by defining the offsets from another node or point
(the option ) or by entering exact coordinates in the property window. As a
result, the rubberbanding circle will pass through the specified node, while staying
tangent to the entity defined by the step one.
Next, specify the radius (diameter) of this auxiliary circle, either by entering a
specific value in the property window, or freely by clicking . As a result, the
position of the auxiliary circle will be fixed. A node will be created at the
tangency point between the circle and the selected entity.
What is left is defining the direction of the arc on the auxiliary circle between the
two nodes. To do this, simply point with the mouse at the desired position. The
rubberbanding arc will be flipping following the pointer. After selecting the
desired position, click , and the arc will be fixed.
