Use the Line Edit panel to split, join, or extend lines.
Location: Geom page
Some subpanel' functions execute automatically when lines are selected, but other
panels (split at line, split at plane, smooth, and extend) require you to click a
green command button located on the right side of the panel.
Combine Subpanel
Use the Combine subpanel to create a new continuous line segment between two existing
lines, resulting in a single seamless line. Once you select both lines, they will be
combined automatically. Figure 1.
Option
Action
1st line
Select the first of
the two lines to combine.
2nd line
Select the second of
the two lines to combine.
smooth /
straight
Choose how to create
connections made between non-collinear lines.
smooth
Created as a curve.
straight
Created as a straight line with angles at the points
where it meets the input lines.
Split at Point Subpanel
Use the Split at Point subpanel to split an existing line into two separate line
segments. The split occurs at a point which you select by clicking the line.
Option
Action
line
Select an input line.
The selected line will remain highlighted. Click the point on
the line where you wish the split to occur. The split will be
made automatically.
Split at Joint Subpanel
Use the Split a Joint subpanel to split a line into separate segments at a joint.
Joints exist where lines have been previously combined, or where geometric features
dictate. Joints are part of the line definition history, so depending on how the
line was created, it may or may not have joints.
Option
Action
lines
Select the input line.
The line will remain highlighted, and any joints associated to
that line will be indicated with a red "V". Click any of the
displayed joints to split the line at that location, and the
split will be made automatically. Figure 2.
Split at Line Subpanel
Use the Split at Line subpanel to split each of the input lines at the point where
they are crossed by another line or lines. You must specify the lines to be split
and the lines that determine the split location separately.
Option
Action
lines
Select the lines to
split.
cut line
Select the line that
cross the input lines where you wish them to be split.
Note: You can only specify a single cut line, even
though you can specify multiple lines to be
split.
Split at Plane Subpanel
Use the Split at Plane subpanel to split each of the input lines at the point where
they are crossed by a user-defined plane. You must specify the lines to be split and
define the plane, either via one of the coordinate axes with a base node, a vector
entity with a base node, or by specifying three nodes and a base node.
Option
Action
lines
Select the lines to
split.
(plane and vector
selector)
Use the standard plane
and vector selector to define the plane that intersects the
lines where you wish them to be split.
Smooth Line Subpanel
Use the Smooth Line subpanel to convert sharp angles or joints in the input lines
into smooth curves instead. You can determine an upper limit allowed for angles, so
that angles below than this limit will be smoothed into curves while the angles
above the limit are preserved.
Option
Action
lines
Select the lines to
smooth.
smooth corners /
approximate lines
Choose a smoothing
behavior.
smooth corners
Convert only sharp angles in the lines to
curves.
approximate lines
Convert the input lines to straight lines that
approximate their current shapes, but exactly
connect their start and end points.
min. tangent
angle
Corners whose angle
relative to the line is less than this value will not be
smoothed.
Note: Only available when smooth corners is
selected.
tolerance =
This setting only
displays when using the smooth entire line option.
approximation
type
Choose an
approximation type: flat parabola or bezier simplify.
Note: Only
available when approximate lines is selected.
Extend Line Criteria Subpanel
Use the Extend Line Criteria subpanel to make an existing line longer, following the
general vector and/or curvature of the input line. You can specify the distance as a
numeric value, or extend the line to a specified node, line, surface, or point.
Option
Action
line
Select the line to
extend. Only one line is accepted. Once selected, the beginning
(origin) of the line is indicated with a red "V". Clicking
extend + will extend the line from
the end point; clicking extend - will
extend from the origin.
distance = /
to:
distance=
Specify a distance to extend.
to:
Select an entity to which the line will be extend to
meet.
Choose between a specific distance to extend, or extending
the line to meet another entity.
Note: Clicking
extend - will extend the line
from the origin by the distance from the origin point to the
selected destination geometry. The extended line will not
necessarily meet the geometry.
follow
curvature
When extending a line,
this option causes the extension to follow the existing line
curvature. If disabled, the extension will form a straight
extension.
capture radius
=
Specify the range that
the extended line must fall within to connect to the target
geometry. If the end of the extended line is within the capture
radius of the target geometry, then the coordinates are mapped
to the target geometry.
Note: Only available when using the to:
extension distance option.
Command Buttons
Option
Action
reject
Undo the most recent
edit.
split
When splitting by a
point, joint, line, or plane, this button performs the split
provided that all necessary criteria are complete.
smooth
Smooth the selected
lines in accordance with the criteria specified.
