\n Projection algorithms allow to define the mesh of a geometrical
|
|
object by the projection of another already meshed geometrical object.
|
|
|
|
<b>Projection 1D</b> algorithm permits to define the mesh of an edge
|
|
(or group of edges)
|
|
by the projection of another already meshed edge (or group of edges).
|
|
\n To apply this algorithm select the edge to be meshed (indicated in
|
|
the field \b Geometry of <b>Create mesh</b> dialog box),
|
|
<b>Projection1D</b> in the list of 1D algorithms and click the
|
|
<em>"Add Hypothesis"</em> button.
|
|
The following dialog box will appear:
|
|
|
|

|
|
|
|
In this menu you can define the \b Name of the algorithm, the algeady
|
|
meshed source \b Edge and the \b Mesh (optional, use it if there are several
|
|
different meshes on the same edge). It could also be necessary to
|
|
define the orientation of edges, which is done by indicating the
|
|
<b>Source Vertex</b> being the first point of the Source Edge and the
|
|
<b>Target Vertex</b> being the first point of the created \b Edge. For
|
|
a group of edges, <b>Source</b> and <b>Target</b> vertices should be
|
|
shared by only one edge of the group. If <b>Source</b> and
|
|
<b>Target</b> vectors are specified, the elements of the group must be ajacent.
|
|
|
|
\n <b>Projection 2D</b> algorithm permits to define the mesh of a face
|
|
(or group of faces) by the
|
|
projection of another already meshed face (or group of faces). This
|
|
algorithm works only
|
|
if all edges of the target face have been meshed as 1D Projections of
|
|
the edges of the source face.
|
|
|
|
To apply this algorithm select the face to be meshed (indicated in the
|
|
field \b Geometry of <b>Create mesh</b> dialog box), <b>Projection
|
|
2D</b> in the list
|
|
of 2D algorithms and click the <em>"Add Hypothesis"</em> button. The
|
|
following dialog box will appear:
|
|
|
|
\image html projection_2d.png
|
|
|
|
In this menu you can define the \b Name of the algorithm, the algeady
|
|
meshed source \b Face and the \b Mesh (optional, use it if there are several
|
|
different meshes on the same face). It could also be necessary to
|
|
define the orientation of mesh on the face, which is done by
|
|
indicating two <b>Source Vertices</b>, which belong to the same edge of the
|
|
source face, and two <b>Target Vertices</b>, which belong to the same edge of
|
|
the created \b Face.
|
|
|
|
\n <b>Projection 3D</b> algorithm permits to define the mesh of a shape by
|
|
the projection of another already meshed shape. This algorithm works
|
|
only if all faces and edges of the target face have been meshed as 1D
|
|
Projections of the faces and edges of the source face. Another
|
|
limitation is that this algorithm currently works only on boxes.
|
|
|
|
To apply this algorithm select the solid to be meshed (indicated in
|
|
the field \b Geometry of <b>Create mesh</b> dialog box), <b>Projection
|
|
3D</b> in the list of 3D algorithms and click the button. The
|
|
following dialog box will appear:
|
|
|
|
\image html projection_3d.png
|
|
|
|
In this menu you can define the \b Name of the algorithm, the algeady
|
|
meshed source <b>3D shape</b> and the \b Mesh (optional, use it if there are
|
|
several different meshes on the same shape). It could also be
|
|
necessary to define the orientation of mesh on the shape, which is
|
|
done by indicating two <b>Source Vertices</b>, which belong to the same edge
|
|
of the source <b>3D Shape</b>, and two <b>Target Vertices</b>, which belong to the
|
|
same edge of the source <b>3D Shape</b>.
