Creating Points Using Projection

To create a projection point of an element on a line, you can use the Projection Point command.

1. Multi-select the elements you want to project onto the line. To multi-select several elements you have two possibilities. Either:

   
   

   • Use the control key before selecting Projection Point .

   • Drag the cursor if the command is already activated.

   
   
   

2. Click Projection Point in the Profile toolbar (Point sub-toolbar).

3. Select the line onto which the element first selected will be projected and on which projection points will be created.

   
   
   

   The projection points automatically appear on the line, as well as construction lines. The points that are projected are perpendicular to the element last selected provided this element is a line. Note that both the selected points and the projected points are associative with the construction lines that are also created. A construction line is created between the original points and the projected ones.

   
   
   

   Tip: The constraints appear on the condition that Geometrical Constraint is active in the Sketch tools toolbar.

You can create associate projected points using the Orthogonal Projection or Projection Along a Direction command.

1. Create a spline and points.

2. Click Projection Point .

   The Sketch tools toolbar now displays two projection options:

   
   

   • Orthogonal Projection (default mode)

   • Projection Along a Direction

3. Select Orthogonal Projection .

4. Select several points.

5. Select the spline.

   
   
   

   All the selected points have been projected onto the spline according to a normal direction at this curve.

   
   
   

   Or

6. Select Projection Along a Direction

7. Select one point.

8. Select the spline.

   
   
   

   The selected point is projected along the given direction.
