Beam - Hidden Line Reference

Lingwisyer · ‎2026-03-10

Hi all,

It seems that the "Hidden Line under Slab" option for beams is evaluted by checking if the Beam Reference Line elevation is less than OR EQUAL to the Slab Reference Line elevation. So if you want to do a stand up beam that is anchored by it's base, it get's hidden, even though it is above the slab... Other than resorting to not using the bottom anchors, is there any other way to get around this?

Ling.

Yeaahhhh I ran into this issue, too. Looks like the programmers did the common < > wrong brackets mishap.

I'd classify this is as a bug, but it always has been like this and nobody bothered to fix it yet.

So no, I don't know any workaround, sadly. 😞
