STL file export, shift coordinates and flip y and z. Intended?
Using AC3D 9.1.0 on linux.
I noticed that an export to STL format flips the Y and Z axis and offsets the coordinates for the vertices to be all positive. Is that intended? If so, why? How to reproduce:
The result of this is that the element exported shows up somewhat rotated and translated. Now I read that STL requires to have only positive coordinates. I also read that this is historic and not required. I do not read anything about the axis flip, but I might not have read the correct sources. If I modify the STL files to contain negative vertex coordinates, AC3D imports that without problems. Could we add settings to control that behavior, similar to OBJ files? |
