-
From the Wireframe section of the action bar,
or within Surfaces Network, click Curves
Network
.
Notes:
- Use curves creation commands to create and add a curve.
- Network geometry and topology actions, for example move a vertex, split a wire or
deform a curve, are not available from Surfaces Network.
- Edition of Curves Network inputs results in recomputing all
already generated surfaces, if any.
-
Under Preparation, select the curves.
They can be a set of curves, surface edges, face boundaries, or another curves
network.
- Median lines of fillets created in Curve Network Preparation
are automatically discarded from the selection.
- Fictive edges can be selected with or without associated border lines. The
associated guiding curve is discarded as are the median lines of fillets.
-
-
To remove a curve from the list, do one of the following:
-
Pick the curve again in the work area.
-
Pick the curve again in the tree.
-
Right-click the curve and select Remove.
- Optional:
Select a support mesh.
-
Set the parameters.
-
Enter the Max distance value.
Below this value, two curves are considered as
intersecting each other.
-
Check the Filtering check box and enter a value to filter
small sliced curves.
-
Set the Automatic tangency value to create a tangency based
on the angle between two connected edges..
-
Go to Freeze to confirm frozen curves,
See Frozen Curves for more information.
- The list of frozen curves is displayed for information (No interaction: You cannot
add curves to the selection and specify them as frozen).
- They are displayed in the 3D area.
- Standard curves: Standard display.
- Fictive edges: Thick dark blue.
- User frozen curves: Dotted dark blue.
- Face borders: Thick green.
-
Click a curve in the 3D area to change
its status.
Possible changes are:
- Standard curve > User frozen > Standard curve.
- Fictive edge > User frozen > Fictive edge.
The display is updated.
-
Click Apply.
- The curves network is computed and displayed.
- The removal of the external wire is automatically proposed.
-
Optional: Under Preparation, select and delete loops
as required.
-
Go to Analyze
-
Select the Sharp/Smooth edges check box to display edges
according to their continuity.
- Sharp edges (with G0 continuity) are displayed in black.
- Smooth edges (with G1 continuity) are displayed in gray.
Note:
The Sharp/Smooth status of standard edges can only be changed in
Surfaces Network.
-
Select the Curve-curves deviation check box to display the
distance between the curves network and the input curves.
-
Select the Curves-polygon deviation check box to display the
maximum distance between the curves network and the support mesh.
-
Click Deviation Analysis
to access the corresponding parameters.
For more information, see Performing a Deviation Analysis.
-
Confirm the creation of the curves network.
- Optional:
To edit an existing curves network.
-
Switch to manual update mode, for better performances.
-
Do one of the following:
- Replace the support mesh to fit to the latest version of the mesh.
- Remove or add previously created curves.
Recommendation:
- Create additional curves lying on curves (and not on previous curves
network).
- Restore the visibility of all the unput curves in on click using
Hide/Show Inputs from the context menu of the curves network.
-
Validate.
