Known Issues in Autodesk Civil 3D 2026.2
This document lists known issues in Autodesk Civil 3D 2026.2.
| Drainage Tools / Civil 3D Installation |
| If you previously installed the Civil 3D 2026.2 Beta, fully uninstall it and reboot before installing Civil 3D 2026.2; otherwise, Civil 3D 2026.2 may not uninstall completely. |
| Drainage Tools: Channels |
| On a site, if two points have the same X and Y value, elevation (Z) will be set to the same value chosen by feature line priority. So, when extracting feature lines from a channel with a rectangular section, two longitudinal lines on the same side will overlap. Because of this, a channel's longitudinal lines may not extract correctly when its section is rectangular, triangular, or a special custom type. |
| Dynamo |
| Input and output ports for Python nodes cannot be renamed. |
| Project Explorer |
| When exporting point groups to a 2D or 3D DWG, subsequent exports from the same Project Explorer session may yield different results from the associated explode operation compared with the initial export. |
| When exporting structures to 3D AutoCAD DWG, some generated AutoCAD entities for the structure may be assigned an elevation of 0.0 instead of the rim elevation of the structure. |
