Building a model for 3D printing requires the model to be a “solid”, which can be checked by looking if a volume is reported in the Entity Info. Solid models are also required for boolean and other operations.
During the construction process the model may have to be repaired after modifications, for example addition or subtraction of solids. On complex models this can be a very time consuming task. The “Fix Solid”, Fredo Tools “Edge Inspector”, “Edit Vertices” and other SU plugins, as well as external programs such as MeshLab are a very great help.
But errors will appear in zones remote from the modification, on previously corrected error-free zones.
Also exporting a SU solid in stl (or other formats) will produce manifold printable files but re-importing the file into SU will result in models with many defects (perhaps hundreds).
The Make Printable service will make a printable file out of almost anything. Curiously, importing these processed files into SU does not produce errors (or it has not happened to me yet). But I have not tested this extensively enough.
Can this be improved in SU so that less solids errors are produced?
