I've got a real conundrum.
I've restarted a project that went off the boil for a while. Client has asked me to change the external cladding from a vertical cladding to a horizontal cladding.
Easy peasy? Yes! ... but no.
For some reason the material (Colorspan Standing Seam) appearance won't change even though the surface pattern has been updated.
I have tried the following:
1. Swap Materials to ones with a different hatch pattern.
2. Removing the outer skin. Even the layer below (with no hatch) is showing the vertical hatch.
3. Tried it in different versions of revit.
4. Looked back to past files ... even early stages.
None of these worked.
The material hasn't got any Paint on it (so unpaint isn't applicable).
Other materials within the file can be updated not a problem ... it just sems to be this wall.
Why are the vertical lines remaining even if the material with the hatch is removed???
I humbly request any help and am willing to share the file to help resolve this.
Revit version 2019 (and also tried on 2020).
