Elements
- Elements
- Lists the elements selected for local join.
Options
- Automatic
Merging
- As soon as at least two edges have been selected, Local
Join tries to find the distance
between these edges at that the two edges could be considered as joined.
This distance is proposed in the box on the right of
Automatic Merging.Automatic Merging uses the distance found as the
Join Merging Distance
for a Join or Join/Heal or the
Heal Merging Distance
for Automatic Join/Heal.
- Join
- Starts only a local join and gives access to the
Join Parameters with the Join Option Definition dialog box.
- Join/Heal
- Starts a local join and a healing, and gives access to the
Heal parameters.
- Automatic
Join/Heal
- Starts both a local join with the Join Merging Distance
criterion and
a local healing with a Heal Merging Distance criterion, i.e. a
simple join is performed on small gaps
and a join plus a healing are performed on larger gaps.
- Join Merging
Distance
- Sets the tolerance at that two elements are considered as being only one
for a Join. It is equivalent to the Merging Distance in the Join Parameters. When you modify
one, the other is updated.
- Heal Merging Distance
- Sets the tolerance at that two elements are considered as
being only one for a Healing.
Join Parameters
Only the Parameters tab is available.
- Check connexity
- Finds out whether the elements to be joined are connex. If
they are not, and the check box is selected,
an error message is issued indicating the number of connex domains in the
resulting join.
Click Preview in the
Checker dialog box. The free boundaries are highlighted to help
you detect
where the joined element is not connex.
- Ignore erroneous elements
- Lets the system ignore elements that would not allow the
join to be created.
- Keep small
elements
- Keeps the elements whose size is inferior to the Join Merging Distance. This can be useful when you relax
the tolerance: Some gaps are hidden but the geometry still has gaps and may
be unusable for later processing. This parameter allows maintaining topology
matched to geometry.
- Simplify
the result
- Allows the system to automatically reduce the number of
elements in the resulting join whenever possible.
- Merging distance
- Sets the tolerance at that two elements are considered as
being only one.
It is equivalent to the Join
Merging Distance. When you modify one, the other is updated.
- Angular
Threshold
- Specifies the angle value below that the elements are to be
joined.
- If the angle value on the edge between two elements is
greater than the Angular Threshold value,
the elements are not joined. An error message appears.
- This is particularly useful to avoid joining overlapping
elements. You can either:
-
Deactivate the check box,
-
Or increase the value of the angular threshold,
-
Or remove all the elements or sub-elements that are in
error.
Heal
Parameters
The options in the
Continuity list are as follows:
- Freeze
- This tab lets you freeze elements, i.e. define elements that
will not be modified.
You can either select
specific elements to freeze, or select automatically all planar elements or
all canonical elements.
- Elements to
freeze
- Lists the elements selected.
- These are elements that
should not be affected by the healing operation.
- You cannot
freeze edges to be joined. If you want to do so, you first need to
freeze the faces.
- You can
edit this list.
- Freeze Planar elements
- Freezes all planar elements found in the
selection to be healed.
Note:
This option is inactive on edges adjacent to surfaces that are not
continuous.
- Freeze Canonical
elements
- Freezes all canonical elements
(including planar elements as they are canonical elements) found in
the selection.
Note:
This option is inactive on edges adjacent to surfaces that are not
continuous.
- Sharpness
- Available for a Tangent continuity. Provided the Tangent continuity mode is active, Sharpness lets you retain sharp
edges, by clicking the tab and selecting one or more edges.
- Edges to keep sharp
- Lists the sharp edges that must remain sharp. You can edit the list.
- Sharpness angle
- Redefines the limit between a sharp angle and a flat angle (the
maximum value). This can be useful when offsetting the resulting healed
geometry for example.
The proposed Sharpness angle is 0.5 degree.
Visualization
The Visualization tab enables you to better understand the
discontinuities in the model and the results of the join/healing command.
For a simple Join command, you can highlight:
- Surface boundaries
- Joined edges
- Unjoined edges.
For a Join/Heal or an Automatic Join/Heal command, you can highlight:
- Surface boundaries
- Joined edges
- Unjoined edges
- Healed edges
- Smoothed surfaces.
After Apply, the number of elements found in each category
appears in the dialog box.
To highlight them in the work area, check the corresponding line.
The elements are displayed with the color displayed beside their callout. A color editor is available on each color patch.
- Output Information
- Displays information on errors (gaps greater than the tolerance) found on
the output elements,
e.g. the elements have been partially healed.
- Input Information
- Displays information on errors (gaps greater than the tolerance) found on
the input elements.
- Interactively
- Displays
textual information as you move the cursor over the edges.
- Sequentially
- Indicates in the counter below the rank and the total number
of errors.
- << or >>
- Displays the information on the previous or next edge.
