edited. Rubberband the segment by the mouse to the desired position and click . This fixes the segment in
the new position.
Editing a Circle, Ellipse, Arc and Elliptical Arc
If the selected element is a circle, ellipse or an arc (except an arc through three points), the second click
on the selected entity launches the mode of editing the radius of the circle, ellipse or arc. A new value of the
radius (diameter) can also be assigned via the property window or by rubberbanding the entity image to the
desired position and clicking .
This way of editing is not suitable for an arc constructed through three points, and an elliptic arc. In this case,
after selecting the arc, you need to select a node the arc is passing through, and move it to the desired
position or enter the new placement coordinates of the node in the property window.
There is yet another way to modify any type of an arc or fillet. Select one of the end nodes of the selected
arc, and then move the rubberbanding image of the arc into the desired position.
After selecting the arc of a circle an additional option becomes available in the automenu:
Change Arc Direction
This option replaces the selected arc with another arc of the same circle. When applying this option to the arc
constructed by 3 points, the middle (second) node of the initial arc is automatically removed.
Editing Spline
After selecting a spline, the automenu gets an additional option:
Switch to “Insert Point” mode
This option allows adding an additional point to a spline. After calling the option, select a spline node nearest
to the additional node location. Then pick the side where the new node should be created with respect to the
selected node, and then define its position.
To edit an existing node, select it after selecting the spline. The node and the whole spline will start
rubberbanding following the pointer. The new position of the node can be specified by simply moving the
pointer to any location and clicking , or by specifying new coordinates of the node in the property window.
The same window provides for entering the new weight value of the node (for splines by control polygon), as
well as the number of spline segments.
To delete an existing spline node, select the node and then use the option .
When editing a spline that was divided or trimmed, one can also change the position of the trimming points
(the intersection points) of the spline image. These points are highlighted when the spline is selected, and
become available for selection. The selected point can be moved along the spline and fixed at a new position
by clicking .
