Generating the Plies and Ramp Support

This task shows you how to:
  • For a problem-free generation of plies, we recommend that:
    • the cells are defined by a closed contour made of at least 2 reference elements,
    • the cells should not use more than two nodes per reference elements (e.g. L-shape cells are OK, U-shape cells are not).
  • The definition of the limitation side of limit contours is taken into account.
  • If you generate a second plies group from a virtual stacking that already contains a plies group, only the plies group created first will be synchronized with the virtual stacking (the second one will not be synchronized).
You must have created a virtual stacking.

Open the RampSupportGA.CATPart document.
 

Edit Ramp Supports

  1. Right-click a ramp support in the specification tree and select Definition in the contextual menu:


    or double-click a Grid Ramp Support node,
    or pick Grid Ramp Support definition and select the ramp support to edit.
    The Grid Ramp Support Definition dialog box is displayed:

  2. Select the Structural element on which the ramp support will be computed.

  3. Decide on which side the ramp will be (Side + or Side -)

  4. If required, define a Ramp Support Fallback Strategy.

Create Ramp Support Curves Automatically

  1. Make sure Automatic ramp curves creation is selected.

  2. By default, the Clearance and slope identical to structural element check box is selected, meaning all the ramp supports will be created with the same clearance and slope as those of the structural element. Modifying the structural element will thus update the ramp supports.

  3. Clear this check box if you want to modify the clearance type and its value, as well as the slop value:

    • Define the type of ramp support:
      • clearance: parallel / ramp: parallels
      • clearance: offset / ramp: parallels
      • clearance: offset / ramp: offsets
    • Define the first curve, either by a distance from the clearance area or by a point (for 45 degrees cut).
    • Define the Slope value:

  4. Define the number of curves (Curves count).

  5. Define the geometry creation options:

  6. Click OK to validate and exit the dialog box.

Create Customized Ramp Support Curves

  1. Select Custom curves creation.
    Another Grid Ramp Support Definition dialog box is displayed:

  2. Select existing curves or use the contextual menu to create some:

  3. Select a bottom ramp curve or use the contextual menu to create one:

  4. Click OK to validate and exit the dialog box.
