Hello there,
Click the rebar that does not change (once), select “edit constraints” from the upper right menu on the ribbon, and constrain the rebar parts to the edge of the columns or to the rebar cover. It should work.
If you click blue dots … for every side of the rebar … you can constrain those sides to edge or rebar cover(dotted line). In the picture, you are constrained to -221.0 from the edge, you can click the blue symbol near the blue arrows and switch it to rebar cover (dotted). Now if you modify a column and the dimension of a not constrained rebar changes … the rebar does not change.
Hi, I have the same problem, only worse: when you change the thickness of the protective concrete layer, the size is adjusted on only one side. Revit 2026 and Sofistic 2026. Sometimes, after rebooting, even this side does not change. When changing the column cross-section, either one side is adjusted or neither side is adjusted.
