Displaying Continuities On Elements

This task shows you how to display continuities on elements and how to modify their values.
Three other types of manipulators can be displayed on a given element, whether the selected or the resulting element:
These manipulators are displayed either by using the Dashboard (P2 only) as illustrated in this task, or by checking the adequate option in Tools > Options > Shape > FreeStyle. Once they are displayed, their behavior is identical regardless of the chosen interface style.

Open the FreeStyle_Part_41.CATPart document.

  1. Click the Match Surface icon and select the two edges to be matched (see Matching Surfaces).

  1. Click the Continuity icon:


Texts indicating the continuity type wherever available are displayed.

  1. Right-click on a text to display the contextual menu, and choose the Curvature continuity item.


You can also simply click the text. It will automatically change to the next type. 
Click as many times as needed to go down to the desired continuity type.
Shift-clicking goes up in the list.

The text changes to Curvature and the elements are updated in accordance.


In some cases the chosen type of continuity is not compatible with the geometry or the modification. In that case, a warning is displayed directly onto the geometry at the location where the inconsistency arises. You can then change the continuity, or modify the geometry itself.
A forbidden sign may even be displayed and the system will prevent you from modifying the element in a specific direction, if it does not make sense geometrically speaking.
