Reflection Lines Analysis Parameters

This section explains the parameters in the Reflection Lines command dialog box.

  • The number of Neons and the spacing between any two neons.
  • The position: this option automatically calculates the position of the neon grid (according to the surfaces).
  • The viewpoint:
    • according to the current work area: reflect lines are re-computed according to the new viewpoint when you are using standard viewing handles.
    • according to the user-defined viewpoint reflect lines do not move, when you are using standard viewing handles, but you can move the eye.

    Use the Edit angle step context menu on the grid handles to allow the rotation of the grid by a value defined within the Step dialog box. In this case, clicking one of the grid handles rotates the grid by the set value.

  • You can select and deselect the analyzed surfaces, while applying the analysis. The reflect lines will appear or disappear respectively.
  • When you select the geometrical set as an input in the tree, all the elements included in this geometrical set are automatically selected too.
  • When you Click User-defined Eye , a dot is displayed (you need to zoom out to locate it) defining the eye and its position. The reflect lines are frozen according to that direction, meaning that you can move the geometry around while keeping the reflect lines static according to that viewpoint. You can move the eye using handles, or using the Edit context menu to precisely define its location.
  • You can drop reflect lines onto the analyzed element. To do this, simply choose the Keep this reflection line or Keep all reflection lines from the context menu displayed when right-clicking either a reflection line itself or one of the grid neons. A curve corresponding to the reflection line is created.
  • A Reflect Lines Analysis is created in the tree. You can therefore create several such analyses on different set of surfaces or on the same set of surfaces but using a different viewpoint.
  • As reflect line analyses are objects, as such they can be edited using the context menu in the tree. You can transfer a reflect line analysis from one element to another, for example. To do this:
    • Double-click the reflect line analysis from the tree.
    • Select the surface on which you wish to apply the analysis. Reflect lines are displayed on that surface provided the grid orientation is adequate.
    • Select the surface on which the analysis existed, to remove it.
    • Click OK in the Reflection dialog box.
