Settings
Add Extra Top Layer if Necessary
Default is on.
When selected, chop will add an extra layer at the very top of the object if the top of the object is more than half the layer thickness above the first slice. This is so the cutting tool doesn't cut too deeply through the top of the object on its first pass.
Extra Decimal Places
Default is one.
Defines the number of extra decimal places export will output compared to the number of decimal places in the layer thickness. The higher the 'Extra Decimal Places', the more significant figures the output numbers will have.
Import Coarseness
Default is one.
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' setting, the wider the gaps in the mesh it will span. An import coarseness of one means it will span gaps of the perimeter width.
Layer Thickness
Default is 0.4 mm.
Defines the thickness of the layer, this is the most important chop setting.
Layers
Chop slices from top to bottom. To get only the bottom layer, set the "Layers From" to minus one. The 'Layers From' until 'Layers To' range is a python slice.
Layers From
Default is zero.
Defines the index of the top layer that will be chopped. If the 'Layers From' is the default zero, the carving will start from the top layer. If the 'Layers From' index is negative, then the carving will start from the 'Layers From' index above the bottom layer.
Layers To
Default is a huge number, which will be limited to the highest index number.
Defines the index of the bottom layer that will be chopped. If the 'Layers To' index is a huge number like the default, the carving will go to the bottom of the model. If the 'Layers To' index is negative, then the carving will go to the 'Layers To' index above the bottom layer.
Mesh Type
Default is 'Correct Mesh'.
Correct Mesh
When selected, the mesh will be accurately chopped, and if a hole is found, chop will switch over to the algorithm that spans gaps.
Unproven Mesh
When selected, chop 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.
Perimeter Width
Default is 2 mm.
Defines the width of the perimeter.
Examples
The following examples chop the file Screw Holder Bottom.stl. The examples are run in a terminal in the folder which contains Screw Holder Bottom.stl and chop.py.
> python chop.py
This brings up the chop dialog.
> python chop.py Screw Holder Bottom.stl
The chop tool is parsing the file:
