button. The following dialog box will appear:
Projection algorithms allow to define the mesh of a geometrical object by the projection of another already meshed geometrical object.
Projection 1D algorithm permits to define the mesh of an edge by the projection of another already meshed edge.
To apply this algorithm
select the edge to be meshed (indicated in the field Geometry
of Create mesh dialog box), Projection 1D in the list of 1D algorithms
and click the button. The following dialog box will appear:
In this menu you can define the Name of the algorithm, the algeady meshed source Edge and the 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 Source Vertex being the first point of the Source Edge and the Target Vertex being the first point of the created Edge.
Projection 2D algorithm permits to define the mesh of a face by the projection of another already meshed face. 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 Geometry of
Create mesh dialog box), Projection
2D in the list of 2D algorithms and click the button.
The following dialog box will appear:
In this menu you can define the Name of the algorithm, the algeady meshed source Face and the 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 Source Vertices, which belong to the same edge of the source face, and two Target Vertices, which belong to the same edge of the created Face.
Projection 3D 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 Geometry of
Create mesh dialog box), Projection
3D in the list of 3D algorithms and click the button.
The following dialog box will appear:
In this menu you can define the Name of the algorithm, the algeady meshed source 3D shape and the 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 Source Vertices, which belong to the same edge of the source 3D Shape, and two Target Vertices, which belong to the same edge of the source 3D Shape.
