Using the Sketcher Grid

1. To display the Grid in the Sketcher session, just click Grid in the Visualization toolbar.
   The grid is displayed. In case the grid spacing and graduations do not satisfy you, you can modify them in the Options dialog box as follows:

2. Select Tools > Options...
   The Options dialog box opens.

2. Select the Mechanical Design category in the left-hand box.

3. Select the Sketcher sub-category.
   The Sketcher tab that appears lets you set different options.
   

4. Set the options according to your needs:

   Display: Defines whether the grid is displayed. By default, this option is selected. Snap to point: Defines whether annotations are snapped to the grid point. By default, this option is selected. Allow Distortions: Defines whether grid spacing and graduations are the same horizontally and vertically. By default, this option is not selected.

Working with the Snap to Point Option 

If activated, Snap to Point available in the Sketch tools toolbar, makes your sketch begin or end on the points of the grid. As you are sketching, the  points are snapped to the intersection points of the grid. Note that this option is also available in the Tools > Options > Mechanical Design > Sketcher option at the left of the dialog box (Sketcher tab).

In the following example:

• the black spline was created with Snap to Point on. The points are on the grid.
• Conversely, the highlighted spline was created with the Snap to Point option deactivated.
  
  

Lock Rotation

The Lock Rotation command restricts the rotation of the sketch view using mouse, in all the directions that are not normal to the view point.

By default, this command is deactivated.

The state of this command is reset once you exit Sketcher. You can use any of the following options to change the orientation of the sketch view even if this command is activated: Robot Normal View Standard view commands
