Beam connect

Charlie64 — Sat, 23 May 2026 14:35:07 GMT

Hi,

I want to connect two beams of different heights, both were made with custom profile.

On the top of the picture i show how i want to connect them, on the bottom of the picture is how they look in profile.

What is the best approach in connecting them?

Thanks!

Have you tried creating a single segmented beam with 3 segments.

The 2 segments at each end can be your different size complex profiles and the one in the middle can be a transition between the two sizes.

This may help ... https://help.graphisoft.com/AC/29/INT/index.htm?rhcsh=1&rhnewwnd=0&rhmapid=#t=_AC29_Help%2F040_ElementsVB%2F040_ElementsVB-41.htm&rhsearch=segmented%20beam&rhhlterm=segmented%20beam&rhsyns=%20

Thanks for the video, but it didn't work.

If i try to do it like in the video, i can't change the joints.

If i do as you said, add a third segment and change the heights, it vanishes.

So i am unsure what am i doing wrong, but they are both custom profiles.

I tried to model it by a segmented beam but couldn't as complex profile is not supported in tapered mode.

So, it can be modeled as 3 different beams, each one has its own profile and with the help of Offset Modifiers in the middle one as follow, hope that helps.

Yes, thank you, this is what i want to make, specifically this one:

I tried to follow your steps, but i missed something, because this is what i get:

basically i can only stretch the whole thing.

if you know what could have gone wrong, i would appreciate it

So sorry, forgot to tell you to change the beam size from uniform to tapered, you'll find start & end offsets.

Great, it works now! Thank you!
