Rounds of Joins

Hi,
How do I know a Join (consisting of several surfaces) round and how an internal edge is to be rounded?
With regards.

Bahari,

A Join is normally done to trimmed surfaces (or curves). Any internal corners (Shape Fillet) should be done first, and that will automatically join the corner with the support surfaces.

(If I misunderstood your question, could you rephrase it and maybe include a picture of your geometry)

Hi Bahari,
Joins can be rounded with the function “edges round”. Select only the function, then the Join. It gives a similar Button to rounds of surfaces! The function has however errors. CATIA V5 tries all edges of the Joins automatically when selected to round.
With regards.
