This kind of selection makes it possible to generate a series of points since a grid directed along two directions, these points are then projected on selected surfaces. These points are created in one 3D sketch. arrows (blue and red) are visible only if one starting point is selected.


 


The principle is to select a series of surfaces, and/or faces, and a summit in order to define a starting point.

It is then enough to select a plan or a face planes for the ''Direction 1''. Selection of the ''Direction 2'' is not obligatory.

  • If the ''Direction 2'' is not selected, the tool automatically defines the direction perpendicular to the ''Direction 1''.

A grid is thus created. It can be displayed graphically by checking the option . The color of this grid is regulated by default on ''Green''.


 


 


The points (color Black) are projected on selected surfaces.

 Only the points meeting surfaces are preserved.

If the result of the outline is not that desired, you can click on the icon  to reverse the direction of the direction or to click on  in order to visualize on which sides the grid is generated.


  • To define a ''Direction 2'', it is enough to select a plan or a face plan. A red arrow positions on the summit selected in order to show the direction, you can click on the icon  to reverse it.

Example : ''Direction 1“ --> '' Plan1” and ''Direction 2“ --> '' Right plan”.



  • ''To be unaware of drillings'':

The selected faces can comprise “holes” (of an unspecified form). While checking this option, the tool will be unaware of the borders of these drillings by creating the points on the missing faces.


  • ''To activate the transparency'':

In the context of a part comprising only surface bodies, this option does not affect really the graphic part.

It is not the case when we work in the comprising context of a part of the voluminal bodies being able to occult part of the preview.

 Only the points meeting surfaces are preserved.

Example : Two selected plane faces define the two directions, a step and a number of points are specified and symmetry was required in the two directions in order to cover all surface.

    • Cases where the option is not checked, only the points located in periphery of the selected face are visible:


 


    • Case where the option is checked. The fact of checking this option, puts the part in transparent mode what makes it possible to see all the points:


 


One can thus realize that according to the ''Direction 2'' it misses points to cover all the face. So we're going to increase the number  to 21 in order to correct that.


 


  • The points being created starting from the starting point (pertaining to the face) and following the two directions, it is possible that the result does not cover all the selected faces.


 


To cure this case of figure, one can either:

    • To click on the icon  in order not to have to enter the number of points.
    • To choose another starting point.
    • To modify the step .
    • Symmetrically to activate the creation of the points to each direction by checking the option .
