This task shows how to heal surfaces, that is how to fill
any gap that may be appearing between two surfaces.
This command can be used after having checked the connections between
elements for example, or to fill slight gaps between joined surfaces. |
|
Open the
Healing1.CATPart document. |
|
-
Click Healing
.
The Healing Definition dialog box appears. |
|
-
Select the surfaces to be healed.
-
You can edit the list of
elements in the definition list:
|
|
If you double-click Add Mode
or Remove Mode, the chosen mode is permanent, i.e.
successively selecting elements will add/remove them. However,
if you click only once, only the next selected element is added or
removed.
You only have to click the button again, or click another one, to
deactivate the mode. |
-
Define the distance below which elements are to be
healed that is deformed, so that there is no more gap, using the
Merging distance as described in Joining
Geometry.
Elements between which the gap is larger than the
indicated value are not processed.
In our example, we increase it to 1mm. |
-
You can also set the Distance
objective, i.e. the maximum gap allowed between two healed
elements. By default it is set to 0.001 mm, and can be increased to 0.1
mm.
-
Click Preview to visualize the
maximum deviation value between the input surfaces
and the result in the 3D geometry.
|
|
The value is displayed on the edge
or the face onto which the deviation is maximal, not exactly where
the maximum deviation is located. |
-
Click OK to create the healed surfaces.
The surface (identified as Heal.xxx) is added to the
specification tree. |
|
|
You can check the Surfaces' Boundaries
option from the Tools > Options menu item, General
> Display > Visualization tab to display the
boundaries. This may be especially useful when selecting, and also to
identify gaps. |
|
|
Sharpness tab
|
|
|
|
- Provided the Tangent mode is active, you can retain sharp
edges and selecting one or more edges.
You can edit the list of edges as described above for the
list of elements to be healed.
- The Sharpness angle allows to redefine the limit between a
sharp angle and a flat angle. This can be useful when offsetting the
resulting healed geometry for example. By default this angle value
is set to 0.5 degree.
- In some cases, depending on the geometry configuration and the set
parameters, the Multi-Result Management dialog box is displayed.
Refer to
Managing Multi-Result Operations for further information.

|
Visualization tab
|
|
|
|
This tab
enables you to better understand the discontinuities in the model and the
results of the healing action.
It lets you define the way the messages are displayed on the smoothed
element. |
|
You can choose to see:
- All the messages, that is to say the messages indicating
where the discontinuity remains as well as those indicating where the
discontinuity type has changed (in point (><) and tangency (^))
|
|
- only the messages indicating where the discontinuity is Not
corrected and still remains
|
|
|
|
|
|
You can also choose to:
- Display information interactively: only the pointers in
the geometry are displayed, above which the text appears when passing the
pointer
|
|
- Display information sequentially: only one pointer and
text are displayed in the geometry, and you can sequentially move from
one pointer to another using the previous/next buttons
