\page reorient_faces_page Reorient faces
|
|
|
|
\n This operation allows changing orientation of faces two ways.
|
|
<ol>
|
|
<li> To reorient a set of neighboring faces by defining the desired
|
|
orientation by a vector. <br> Since the direction of face normals in
|
|
the set can be even opposite, it is necessary to specify a control
|
|
face whose normal will be compared with the vector. This face can be
|
|
either <ul>
|
|
<li> found by proximity to a given point or </li>
|
|
<li> specified explicitly. </li>
|
|
</ul> </li>
|
|
<li> To reorient faces with relation to adjacent volumes. </li>
|
|
</ol>
|
|
|
|
Orientation of a face is changed by reverting the order of its nodes.
|
|
|
|
<em>To change orientation of faces:</em>
|
|
<ol>
|
|
<li>In the \b Modification menu select <b>Reorient faces</b>
|
|
item or click <em>Reorient faces</em> button in the toolbar.
|
|
|
|
<center>
|
|
\image html reorient_faces_face.png
|
|
<em>"Reorient faces" button</em>
|
|
</center>
|
|
|
|
The following dialog box will appear:
|
|
|
|
<center>
|
|
\image html reorient_2d_point.png "First mode: to reorient adjacent faces according to a vector. The control face is found by point."
|
|
<br>
|
|
\image html reorient_2d_face.png "Second mode: to reorient adjacent faces according to a vector. The control face is explicitly given."
|
|
<br>
|
|
\image html reorient_2d_volume.png "Third mode: to reorient faces with relation to adjacent volumes."
|
|
</center>
|
|
|
|
<li>In this dialog
|
|
<ul>
|
|
<li>Specify either of the tree operation modes.</li>
|
|
<li>Select the \b Object (mesh, sub-mesh or group)
|
|
containing faces to reorient, in the Object Browser or in the 3D
|
|
Viewer.</li>
|
|
<li>To reorient according to vector: <ul>
|
|
<li>Specify the coordinates of the \b Point by which the control face
|
|
will be found or the control \b Face itself. You can easy specify the \b
|
|
Point by either picking a node in the 3D Viewer or selecting a vertex
|
|
in the Object Browser. It is possible to pick the \b Face by mouse in
|
|
the 3D Viewer or enter its ID.</li>
|
|
<li>Set up the \b Direction vector to be compared with the normal of the
|
|
control face. If you pick a node in the 3D Viewer then the \b Direction
|
|
vector will go from the coordinate system origin to the selected node.
|
|
If you pick two nodes (holding Shift button) then the \b Direction vector
|
|
will go from the first to the second node.</li> </ul> </li>
|
|
<li>To reorient according to volumes: <ul>
|
|
<li>Select an object (mesh, sub-mesh or group) containing
|
|
reference \b Volumes, in the Object Browser or in the 3D
|
|
Viewer.</li>
|
|
<li>Specify whether face normals should point outside or inside
|
|
the reference volumes using <b>Face normal outside volume</b>
|
|
check-box.</li></ul> </li>
|
|
</ul>
|
|
</li>
|
|
|
|
<li>Click the \b Apply or <b>Apply and Close</b> button to confirm the operation.</li>
|
|
</ol>
