Frustrating inclination inaccuracy

Achille Pavlidis — Tue, 22 Jul 2025 13:49:57 GMT

I have designed beams and slabs with a slant inclination of 2.86 degrees

When I looked at a section, I noticed a slight discrepancy between the beam, and a line drawn with the same 2.86 degree inclination

I placed 2 angle measures and the line correctly displays 2.8600 degrees but the beam shows 2.8624 degrees

Why is this happening???

That is curious. Could it have anything to do with Reference Axis position or the Start/End Angles of the Beam?

Can you should the settings of the Beam and exactly how you modeled it?

I tried to replicate it, but for me, it worked fine in Ac28.

I would think the problem is: for whatever reason Beam Slant Angle displays 2 decimals even if you are using 4-decimal precision working units. Doesn’t the beam inclination get “fixed” if you overwrite (retype) 2.86 into the Beam Slant Angle settting field in the Info Box (which is displaying 2.86 but thinking 2.8624NN…; “fixed” in quotes because sticking with two decimals would require modifying slopes and perhaps positioning of all beams; alternatively, sticking with the base geometry inclination requires forgetting about rounded hundredths, and just never forgetting that beam settings displays a rounded value)?
