3 face blend

I was looking over the SW forum area and notice an old thread that talks about the SW 3-face blend function not working correctly. This was a back in 2011. Our beloved @MLombard even commented on it. Anyway the users were asking if this issue was resolved yet..nope not yet.

Anyway, does SE offer a 3-face blend (aka full round)? Just curious as I can't seem to find it. Sounds like a pretty simple and useful feature if not.

Hi @RyanM,


Are you refering to a 3-Way tube/pipe this one? [made by way of surfacing tools]

Hi @RyanM


Do you have a link to the SW forum post, to visually know what the blend looks like ?

A detailed video on 'everything about blends in SE' is this one by Ally PLM:

Hi @RyanM,


Solid Edge doesn't provide "direct" feature or option for this (If I understand clear your question). There is a "blend" option, but it works well with two surfaces.


I have little experience in VISI (parasolid based CAD/CAM system), it has a very strong surface functionality.


Here is a video what it can do with three surfaces:


Yes, it would be nice in Solid Edge for modelin plastic part.

This is eaxctly what I thinking of for a 3-face blend. Basically it is a side, tangent, side blend. You do it most commonly on plastic injection molded parts that have ribs. In the video they show using it as a slot-type cutout. I'm not sure I'd use a calculation intense feature like that.


Here's the link to the SW forum thread.


This shows how their tool doesn't calculate a uniform curvagture across the 3 faces.

Here's the NX version.


When I was chairing the NX Design and Assy SIG for PLM World this feature was one of the projects we workded directly with development and product managers with to design.

NX is an other playground... But Solid Edge needs for some rethinking on this area... Smiley Wink
