Displays information about the network, allows inspection of curve segments and sculpt curves, and recommends fixes for problems
with continuity.
Show network information
- Choose CrvNet Tools > Analyze Network.
The tool displays information about components of the current curve network.
- Press and hold on a curve segment or sculpt curve to show more information, including a recommendation on how to edit the
network if continuity could not be achieved.
Analysis
The tool labels the curve network with the following information:
Network component |
Indicated by |
Intersections |
Red dots |
Continuity type for each curve segment |
Label at the midpoint of the curve segment (or ).
|
Curve segments with at least one adjacent surface |
White lines |
Curve segments with no adjacent surfaces |
Green lines |
Sculpt curves |
Red lines |
Pinned curve segments |

Note
If the tool fails to build a surface in a valid closed region of the network, the edges are displayed in red. When this happens,
query the edge (see below) to obtain more information about the probable cause of the failure.
The tool also lets you select curve segments and sculpt curves to get specific information:

or .If continuity was not achieved, the tool will give a recommended action.

(for curve segments where continuity was not achieved)
|
A recommendation for how to modify the network so that the curve network can achieve the requested continuity. |
If the curve network could not achieve the requested continuity at a particular curve segment, the tool will recommend a course of action to fix the problem and achieve the requested level of continuity:
Note
The Recommended Action is only an educated guess. In many cases it is impossible to pinpoint the exact reason why continuity
could not be achieved.

Suggestions |
|
One or more of the surfaces meeting at one of the intersections that define the curve segment is a degenerate surface. |
The intersection causing the problem is indicated with an arrow.Try to redefine the network with curves that do not require
degenerate surfaces.
|
|
One of the intersections that defines the curve segment may be part of a region with more than four sides. |
The intersection causing the problem is indicated with an arrow.Try to redefine the network with curves that do not require
non-rectangular surfaces.
|
|
There may be a conflict between the normals or curvatures of the surfaces (outside the network) which meet at this intersection.
|
The intersection causing the problem is indicated with an arrow.Check the alignment of the surfaces at the endpoint of the
curve segment, and reshape to provide required continuity.
|
|
One or both of the curves intersecting this curve segment do not have sufficient curvature quality.
|
The intersection causing the problem is indicated with an arrow.Use the measurement tool to check the curvature of the intersecting curves.
|
|
The curves intersecting this curve segment are badly misaligned.
|
Check the alignment of both pairs of curve segments. |
|
One or both of the curves intersecting this curve segment have some kind of quality problem.
|
Turn on display of edit points and look for bunched up edit points on the intersecting curves.Use the measurement tool to check the curvature of the intersecting curves.Use the tool to smooth the intersecting curves.
|
|
The curves that this curve segment belongs to has some kind of quality problem.
|
Turn on display of edit points and look for bunched up edit points.Use the measurement tool to check the curve’s curvature.Use the tool to smooth the curve.
|
|
The curve that this curve segment belongs to may have “bunched up” edit points or multi-knots.
|
Edit or rebuild the curve to spread out the edit points. |
|
The curves defining a triangular region are too complex.
|
Use the tool to reduce the number of edit points in the curves.Use the smooth tool to remove sharp bends in the curves.
