Upgrading Models to Ramp Definition

You can upgrade pre-V6R2018x models to use ramp definitions.

This task shows you how to:

Process 3DXML Files or Saved Files

You can upgrade pre-V6R2018x models that have been saved, or exported as 3D XML files, to use ramp definitions.

  1. Open the model:
    • Either import the model selecting Add > Import > 3D XML.
    • Or search the model and open it.
    A dialog box informs you an upgrade is required.
  2. According to your need:
    1. Click Cancel to refuse the upgrade (not recommended).
    2. Click OK to accept the upgrade (recommended).
    3. Copy the initial model in the selected directory.
    An Upgrade Report is displayed.

    • Ramp definitions are created for all staggerings on each reference element groups, reference element (Including sub-staggering) and ramp support.
    • Generative Shape Design features such as parallel and offset-intersect are not upgraded (No geometry change).
    • Empty ramp supports are not migrated.
    • If there is only one custom ramp support for a given side and sub-staggering, the corresponding ramp definition becomes the reference for the reference element sub-staggering.
    • Ramp supports with a staggering defined from the reference element may have a specific ramp definition after upgrade:
      • Either because the material thickness used by the slope defined by rate/angle was defined at the ramp support level, not at the reference element level.
      • Or a specific smoothing was used at the ramp support level. Upgrade creates an overriding smoothing.
    • Ramp supports with a ramp support curve as reference are no longer supported. The ramp support is changed to a custom ramp support, with corresponding curves stored under a dedicated open body before stacking.
    • A Ramp Definitions node is created under Composites Parameters in the tree.
    • A Ramp Definitions tab is added in the Composites Parameters dialog box.

Import a V5 File

You can import a CATPart from V5.

Import the model selecting Add > Import > CATIA File.
If relevant, the model is upgraded automatically to use ramp definitions.
