Constructing Arcs
Sketch. Creating a Non-parametric Drawing. Automatic parameterization mode
As is the case of line segments, the set of icons for creating various types of
arcs is in the pull down menu. Any of the enclosed icons can be displayed at
the top level of the automenu when sketching. Usually, it is the icon
corresponding to the last used option in this command.
Arc by three points
Arc by three points
This option defines the mode of creating an arc by three
points. The first and third points are the end points of
the arc. The second point defines the arc position.
The arc can be arbitrarily input by selecting three points
with the mouse, or specified exactly in the property
window. In the latter case, the second point is defined
in absolute coordinates or by the offsets with respect to
the first point of the arc. To define the third point, one
can use absolute coordinates, the radius, the diameter or
the angular length of the arc in various combinations.
The coordinates of any point of the arc can be specified by offsets with respect to a selected point
or node in the drawing with the option ( ).
Arc by two points and radius
To create and arc by two nodes, turn on the automenu option:
Arc by two points and radius
Use the mouse or the property window to define the two end points of the arc being
created. After that, the arc will start rubberbanding on the screen following the
pointer. To fix the arc, move the pointer to the desired position and click , or enter
the value of the angle or the arc radius (diameter) into the property window.
