String Tools

Your application provides a rich selection of tools for editing strings in a 3D window.

Here's a sample of the commonly-used commands.

Menu Command	Quick Key	Description
Extend	ext	Extends a string by adding new points to the end of it.
Extend to string	ess	Extends a string from its end point, using the bearing and dip of the final segment, to a point where it meets another selected string. This is not necessarily an intersection as the strings may be in different planes.
Break at point	bs	Breaks a string at a selected point.
Break with string	bks	Breaks a string where it is crossed by another selected control string.
Break at intersections	bki	Breaks a selected strings at points where it intersects another string.
Connect	conn	Joins two strings together by creating a link between a selected end of each.
Reverse	rev	Reverses the point order of a selected string.
Expand - Expand	exp	Creates a new string by offsetting a selected string by a specified distance in the view plane. The offset is measured perpendicular to each segment on the selected string and there is a prompt for selecting which direction to expand the string and the offset distance.
Expand - Merge segments	-	Creates a single string from string segments with common end points.
Shrink string	ois	Make a circular arc joining three points.
Expand Outside String	oos	Creates a new string by offsetting the selected string by a specified distance in the view plane. The offset is measured perpendicular to each segment on the selected string and will be on the outside of a closed string.
Combine	com	Generates a single string from two overlapping strings. The combination replaces both strings with a single string which consists of one side of the overlap from each string (selectable). This will have the attributes of the first selected string.
Keep originals	ko	Switch used in conjunction with combine-strings. When on, original strings are retained as well the new "combined" string. When off, only the "combined" string is retained.
Clip to perimeter	ctp	Deletes string data inside or outside selected perimeter.
Trim to string	tri	Trims strings against a selected control string.
String trace	stra	Creates a new string from selected intersecting segments of existing strings.
Rapid digitize mode	rap	Toggles the capability to incorporate sections of other strings in a new string. All the sections between two snapped points of an existing string will be highlighted as part of the new string.
Ramp by 3 points	r3	Creates a ramp by joining three points: a start, an end and a third point,selected interactively, on the arc.
