I was not sure where to put this but the problem is follows:
In the building's facades I have a repeating pattern, which needs to be exact in elevation drawings. The easiest way to do this would be using a custom fill in walls. I ran into a problem however.
I attached a couple of pictures of two walls where you can see that the texture is set in 3D view to begin from the lower left corner of the wall element (small red arrows). The only thing that is different about the two wall elements is that they are initially drawn into different directions from the starting point of the wall (arrows show the direction of drawing. The fill pattern is mirrored in the leftmost wall element and is repeated into the wrong direction (the opposite one compared to the fill generation tool).
The biggest gripe about this is that this behavior appears to be somehow hard-coded into the wall elements, because none of the wall's settings appear to have any effect on this. The only thing that seems to make a difference is how the wall was initially drawn. The only way to change this later on is to delete the wall along with all doors and windows and to create a new one.
Am I missing something or do walls in Archicad seriously work like this?
I suppose there's a workaround of making a mirrored texture but even then I would have to check every wall if it's being displayed correctly or not... Also I don't think there's ever any reason for the 2d fill texture to be mirrored this way so I'm beginning to think this is a bug. This is in AC22 FIN (build 7000), 64bit.
