This operation allows extraction of sub-shapes from a given
|
|
shape.
|
|
|
|
To use this operation, select in the Main Menu <b>Operations -> Extract and Rebuild</b>.
|
|
The following dialog box appears:
|
|
|
|
\image html extract_rebuild.png "Extract and Rebuild Dialog"
|
|
|
|
In this dialog:
|
|
<ul>
|
|
<li> \b Name is a result object name.</li>
|
|
<li> <b>Main Object</b> is the main object selected for the operation. It is
|
|
possible to select the object in the Object Browser or in the viewer using
|
|
"selection" button.</li>
|
|
<li> <b>Sub-shape type</b> is the type filter for sub-shapes to be chosen
|
|
for the extraction.</li>
|
|
<li> <b>Filtered shapes</b> is the list of filtered sub-shape IDs available
|
|
for the extraction.</li>
|
|
<li> <b>Shapes to extract</b> is the list of sub-shape IDs to be extracted
|
|
grouped by shape types.</li>
|
|
<li> \b >> is the button to copy object IDs from <b>Filtered shapes</b> to
|
|
<b>Shapes to extract</b>.</li>
|
|
<li> \b << is the button to copy object IDs from <b>Shapes to extract</b> to

|
|
<li> \b Rebuild is the button to perform extraction and show the operation
|
|
statistics.</li>
|
|
<li> The block of \b Statistics shows how many shapes of a certain type
|

are \b Removed, \b Modified and \b Added.</li>

<b>TUI Command:</b> <em>geompy.MakeExtraction(theShape, theListOfID),</em>
|
|
<br> where \em theShape is the main shape, \em theListOfID is a list of
|
|
sub-shape IDs to be extracted.
|
|
|
|
Our <b>TUI Scripts</b> provide you with useful example of the use of
|
|
\ref swig_MakeExtraction "Extract and Rebuild" functionality.
|
|
|
|
<b>More details</b>
|
|
|
|
If a sub-shape is extracted, all its ancestors should be modified. An ancestors
|
|
of extracted sub-shapes can be either:
|
|
- created anew without extracted sub-shapes, or
|
|
- extracted if it is not possible to create a valid shape without extracted
|
|
sub-shape.
|
|
|
|
E.g. it is necessary to extract the vertex from the box:
|
|
|
|
\image html extract_init.png "Extraction of the vertex from the box"
|
|
|
|
In this case 3 ancestor edges are removed as they can't be valid without
|
|
this vertex. 3 faces that contain these edges are also removed. It is because
|
|
the wires without edges are not closed and it is not possible to create
|
|
a valid face on not closed wire. These wires should contain two remaining
|
|
edges, but they are removed as they are the part of the remaining shell.
|
|
So these wires become empty that means that they should be removed as well.
|
|
|
|
The shell is replaced by another one that contains 3 not modified faces. As
|
|
It is not possible to construct a valid solid from not closed shell the solid
|
|
is removed. So the result of the extraction is a shell that contains 3 faces:
