Carve shape is a script to carve a list of slice layers.
Carve carves a list of slices into svg slice layers. The 'Layer Thickness' is the thickness the extrusion layer at default extruder speed,
this is the most important carve preference. The 'Perimeter Width over Thickness' is the ratio of the extrusion perimeter width to the
layer thickness. The higher the value the more the perimeter will be inset, the default is 1.8. A ratio of one means the extrusion is a
circle, a typical ratio of 1.8 means the extrusion is a wide oval. These values should be measured from a test extrusion line.
Rarely changed preferences are 'Import Coarseness', 'Mesh Type', 'Infill in Direction of Bridges' & 'Layer Thickness over Precision'.
When a triangle mesh has holes in it, the triangle mesh slicer switches over to a slow algorithm that spans gaps in the mesh. The
higher the import coarseness, the wider the gaps in the mesh it will span. An import coarseness of one means it will span gaps the
of the perimeter width. When the Mesh Type preference is Correct Mesh, the mesh will be accurately carved, and if a hole is found,
carve will switch over to the algorithm that spans gaps. If the Mesh Type preference is Unproven Mesh, carve will use the gap
spanning algorithm from the start. The problem with the gap spanning algothm is that it will span gaps, even if there is not actually a
gap in the model. If the infill in direction of bridges preference is chosen, the infill will be in the direction of bridges across gaps, so
that the fill will be able to span a bridge easier.
The 'Layer Thickness over Precision' is the ratio of the layer thickness over the smallest change in value. The higher the layer
thickness over precision, the more significant figures the output numbers will have, the default is ten.
The output will go from the "Layers From" index to the "Layers To" index. The default for the "Layers From" index is zero and the
default for the "Layers To" is a really big number. To get a single layer, set the "Layers From" to zero and the "Layers To" to one.
To run carve, in a shell type:
> python carve.py
The following examples carve the GNU Triangulated Surface file Screw Holder Bottom.stl. The examples are run in a terminal in the
folder which contains Screw Holder Bottom.stl and carve.py. The preferences can be set in the dialog or by changing the preferences file
'carve.csv' with a text editor or a spreadsheet program set to separate tabs.
> python carve.py
This brings up the dialog, after clicking 'Carve', the following is printed:
