Extending objects

You can extend only arcs (This includes elliptical arcs and arcs resulting from the conversion of Bézier curves, ellipses, elliptical arcs and True Type text letters.) and regular lines. When you extend a line or an arc, it is extended either by a fixed distance or to its nearest point of intersection with another geometric object. If no length is specified by which to do the extension and no object is lying on the extension path of a line, you can define the end point of the extended line manually. If no length is specified and no object is lying on the potential extension path of an arc, the arc is completed to a circle.

Extending a line

1. Do any of the following:

• On the Transformation toolbar, click Extend .
• On the Transformations menu, click Extend.
• Press CTRL+T+E.

A contextual edit bar appears above the graphical area.

2. Consider the following situations:

TO EXTEND TO NEAREST POINT OF INTERSECTION WITH ANOTHER OBJECT

1. Ensure that dL is either (1) empty or (2) the value in it is 0.00 and that the Use Selected button is not pressed in.
2. Point to the half of the line segment which you want to extend.

If there is at least one object lying on the potential extension path, the line is extended to the first intersection point. The distance between the line end and the intersection point appears in dL.

3. Click to fix the extension.

TO EXTEND TO NEAREST POINT OF INTERSECTION WITH A SELECTED OBJECT

1. Ensure that dL is either empty or the value in it is 0.00 and that the Use Selected button is pressed in.
2. It applies only to lines which have common points of intersection with selected objects in the drawing: when you have selected objects and the Use Selected button is pressed in, the program will extend the objects that have points of intersection with the selected objects only in reference to the selected objects, overriding points of intersection with unselected objects.

NOTE: When no objects are selected in the graphical area, the Use Selected button is unavailable.

TO EXTEND BY A FIXED LENGTH

1. In dL, enter the distance by which you want to extend the object, and then press ENTER.

Nothing will take place that you can see on the screen.

2. Rest the mouse pointer over the half of the line which you want to extend.
3. Click to fix the extension.

NOTE: In this procedure, even if the Use Selected button is pressed in, its utility is overridden.

TO EXTEND BY A MANUALLY SET DISTANCE

1. Ensure that dL is either empty or the value in it is 0.00 and that no objects lie on the extension path of the line.
2. To do this, click the half of the line that you want to extend, and then release the mouse button and move the mouse in the direction you want.

A sample of the extended line appears following the movement of the pointer.

3. Click to fix the extension.

NOTE: You can use this procedure also to decrease the length of a line: (1) Click the line, and then (2) Move the mouse pointer along the line.

Extending an arc

1. Do any of the following:

• On the Transformation toolbar, click Extend .
• On the Transformations menu, click Extend.
• Press CTRL+T+E.

A contextual edit bar appears above the graphical area.

2. Consider the following situations:

To extend to the nearest point of intersection with another object

1. Ensure that dL is either empty or the value in it is 0.00 and the Use Selected button is not pressed in.
2. Rest the mouse pointer over the half of the arc which you want to extend.

If there is at least one object lying in the potential extension path along the circumference, the arc is extended to the first point of intersection. The distance between the line end and the intersection point appears in dL.

3. Click to complete the extension.

To extend to full circle

1. Ensure that the dL is either empty or the value in it is 0.00.
2. Ensure that no objects lie on the extension path of the arc in the respective direction.
3. Rest the mouse pointer over the arc.

The length to be added to the arc to effect the extension appears in dL.

4. Click to complete the extension.

The arc is extended to a full circle. In the Objects tab in the tabular area, the object Arc has become Circle.

To extend to the nearest selected object

1. Ensure that dL is either empty or the value in it is 0.00 and that the Use Selected button is pressed in.

NOTE: When no objects are selected in the graphical area, the Use Selected button is unavailable.

To extend by a fixed length

1. In dL, enter a distance by which to extend the arc, and then press ENTER.

Nothing will take place that you can see on the screen.

2. Rest the mouse pointer over the half of the arc which you want to extend.
3. Click to fix the extension.

NOTE: In this procedure, even if Use Selected button is pressed in, its utility will be overridden.

IMPORTANT: If the value in dL exceeds the extendable length between the two ends of the arc and you extend the arc, the extension will result in a full circle plus an arc overlapping a section of this circles. In such a case, only the overlapping arc appears. Such a situation could happen:

When in the process of applying several successive extensions to the same arc you use a fixed dL value, you finally reach an end-to-end "missing" circumferential arc length, which is smaller than the dL value, but you apply the extension nonetheless.
