Aligning a Cloud Using the Previous Transformation

You can use the last computed transformation to reposition a cloud of points with respect to reference elements..

Before you begin: Align with Previous Transformation requires you have access to Digitized Shape Preparation.
  1. Select a geometrical set as Define In Work Object to store the output.
  2. From the Digitized Data section of the action bar, click Align with Previous Transformation .
  3. Select the References (Either a set of clouds or meshes or surfaces, or a set of points).
  4. Use Hide/Show as required.
  5. Decide to keep the initial cloud or not.

    By default, the Keep Initial check box is selected:

    • The initial cloud to align is kept as such.
    • A copy of this initial cloud to align is made and appears in the tree.
    • This copy is aligned with the references.

    1. Clear this check box if you do not want to create a copy of the initial cloud to Align, for example because of its size. The initial cloud to align itself is aligned with the references.

      Note: To avoid inconsistencies, you cannot clear the Keep Initial check box in the following two cases:
      • When the geometry of the cloud to align is shared by other cloud elements, for example when the cloud to align shares points or vertices with another cloud without any parent/child relationship between them. Clearing the Keep Initial check box would move the other cloud together with the cloud to align, which you do not want to.
      • When the cloud to align is a feature, for example a Generative Shape Design transformation feature.

  6. Click Apply.
    Align with Previous Transformation applies the computation used by the last alignment action to the selected cloud and previews the moved cloud.

  • If Keep Initial is selected, a new cloud, in fact the copy of the initial cloud to align, is created, and aligned with the references. The new cloud has the same graphic properties as the initial cloud to align.
  • If Keep Initial is not selected, the cloud to align is aligned with the references and no new cloud is created.
