Hello Illuminarti, thank you for your knowledgeable reply: yes, the cca 130x130 mm model is warping up, so I will adjust the start of fan from (say) 10th layer up. You are probably right not to use the raft too. I tried to export various STL files from Revit and ALL gcode files from Cura 13.04 show NO slab in the bottom at all. I inspected it by the right hand slider to the Layer 1... Funny thing is that there, where no slab should appear, there is a slab in gcode and there where it should be, there is no slab at all... The walls are sitting correctly on the the slab in Revit model (0 mm) and they are joined with the slab too (in Revit) and the STL file shows the slab correctly too. But after slicing in Cura the slab is still missing. And the slab is 3mm thick in the model. I am little bit desperate about this condition... BTW if I export STL from Revit with just the slab, Cura will slice it correctly... Any ideas how to proceed would be much appreciated!
Hello mgg942, thanks for idea, but I can not join the walls and the slab into one solid before exporting the STL from Revit
software, because these two are separate families and I am searching the most logical way how to make correct 3D prints and maintain correct Revit model too... Anyway thanks!
Mike
