Creating Angle Cuts

1. Click Grid Angle Cut definition .
   The Angle Cut Definition dialog box is displayed:
   

2. Select the plies to be cut. To do so, pick a vertex on each ply.
   The ply is added to the list in the dialog box.
   
   As you pick the vertex, or as you select a line in the dialog box, the ply is highlighted in the 3D window.
   

3. Select one Staggering shape:

   : With plies extensions, : Without plies extensions.

4. In the dialog box, select the ply on which you will define the first angle cut:
   
   Note the dotted-line trihedron that displays the default orientation (in orange) of the angle cut. It is not selectable but you can change that direction by clicking Next. You can also set that direction in the Angle Cut init Definition dialog box.

5. Click Define Angle cut Init. The Angle Cut init Definition dialog box.
   

6. Define the Angle in Direction definition:

   either type the value in the dialog box, or select an arrow in the 3D window: pick an arrow to select it, right-click an arrow to move it by 90 degrees.

7. Type the value of Extrapol length 1 for the start of the corner cut.

8. Type the value of Extrapol length 2 for the end of the corner cut.

9. The extrapolation length must be sufficient to cross all the plies that will have an angle cut.
   
   Click Preview:

   an orange arrows shows the direction of the angle cut, a white line is displayed. This is the Preview of the line that defines the minimum length curve at the cut angle from which new support curves will be created:

10. Click OK in the Angle Cut init Definition dialog box to validate and revert to the main dialog box.

11. Define the Staggering:

    either as same as ramp support #1 (as found in first column Grid Ramp Support), or as same as ramp support #2 (as found in second column Grid Ramp Support), or as a custom ramp support. When this option is selected, the Slope value parameters become available. See Editing Ramp Supports for more information.

12. Click OK when you are satisfied to validate and exit the Angle Cut Definition dialog box.The Grid Angle Cut is created:
    
    Make sure that the extrapolation distances are sufficient to cross all the plies that will have an angle cut, and that you have picked the vertices in proper order. Otherwise, a message will appear:
    Minimum length could not be respected for some plies. Please adjust the staggering value in the chamfer area.

About the Angle Cut init Definition Dialog Box

In the Grid Angle Cut definition command, this dialog box is initialized by the selections you have made.
You can also access the Angle Cut init Definition dialog box with Grid Angle Cut Init definition . In this case, the fields will be empty.

It is used to define a curve of minimum length (in green below), with a given angle that will initialize the new support curves (in pink below):

Panel

It is the Grid Panel you want to process, the one you have selected when entering the Angle Cut Definition dialog box.

Point definition

Defines the reference point (middle point on the green curve below).
You can either select an existing point, or select two intersecting curves.
When you select the last vertex, the two curves that intersect and form this vertex are used to populate the dialog box.

Direction definition

Defines the direction of angle cut computed from a rosette transfer, either by an angle or a direction.

Minimum length

Defines the minimum length of the curve (in green) that initializes the modified support curves.

Extrapol length 1 and 2

Define the extrapolation length on each side of the reference point, to define the end points of the minimum length curve.

Direction

Clicking Direction has the same effect as picking the arrows in the 3D Viewer.
The number below show the correspondence between the pick and the result on the direction:
