\page create_complex_obj_page Creating Complex Objects

<b>New entity -> Generation</b> sub-menu allows creating new geometric
objects by modification and multiplication of the existing objects: 


<ul>
<li>\subpage create_extrusion_page "Extrude" a 2D object by vector,
creating a 3D object. </li> 
<li>\subpage create_revolution_page "Revolve" an object around an
axis, creating a body of revolution.</li>
<li>\subpage create_filling_page  "Create a surface" from a set of edges.</li>
<li>\subpage create_extrusion_alongpath_page "Extrude an object along a path", 
creating a more complex trajectory object.</li>
<li>\subpage create_pipe_path_page "Restore Path" of a pipe-like shape.</li>
<li>\subpage create_thickness_page "Thickness" operation that allows to add a thickness to objects.</li>
</ul>

<b> New entity -> Advanced </b> sub-menu allows creating new geometric
objects using advanced algorithms: 

<ul>
<li>\subpage create_smoothingsurface_page "Smoothing surface" from a
  cloud of points. </li> 
</ul>
