This type of selection allows you to generate a series of points from a grid oriented in two directions; these points are then projected onto the selected surfaces. These points are created in a 3D sketch. The arrows ( blue and red) are visible only if a starting point is selected.


 


The idea is to select a set of surfaces and/or faces and a vertex to define a starting point.

Next, simply select a plane or a flat surface for " Direction 1." Selecting " Direction 2 " is optional.

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

This creates a grid. It can be displayed graphically by checking the option . The color of this grid is set to '' by default.Green''.


 


 


The dots ( black) are projected onto the selected surfaces.

Only points where surfaces meet are retained.

If the preview result is not what you want, you can click on the to reverse the direction or click on to see which sides the grid is generated from.


  • To define a ''Direction 2Simply select a plane or plane face. A red arrow is positioned on the selected vertex to show the direction, you can click on the icon to reverse it.

Example: " Direction 1 " --> "Plan 1" and " Direction 2 " --> "Right Plan."


 


  • " Ignore the holes ":

The selected faces may contain "holes" (of any shape). If you check this option, the tool will ignore the boundaries of these holes and create points on the missing faces.


  • " Enable transparency ":

In the context of a scene consisting solely of surface bodies, this option does not really affect the graphics.

This is not the case when we are working in a scene that contains solid objects that may obscure part of the preview.

Only points where surfaces meet are retained.

Example: Two selected flat faces define the two directions; a step size and a number of points are specified, and symmetry has been applied in both directions to cover the entire surface.

    • If this option is not checked, only the points located at the edge of the selected face are visible:


 


    • When this option is checked. Checking this option sets the part to transparent mode, allowing you to see all the points:


 


We can thus see that according to the ''Direction 2We need more stitches to cover the whole face. So we're going to increase the number to 21 to correct this.


 


  • Since the points are generated from the starting point (which belongs to the face) and extend in both directions, the result may not cover all of the selected faces.


 


To address this situation, you can either:

    • Click on the so you don't have to enter the number of points.
    • Choose a different starting point.
    • Change pitch .
    • Enable the creation of points symmetrically to each direction by checking the option .
