This tool converts a STL/OFF/PLY/OBJ into binary STL Format. The STL then gets unfolded (flattened) to make a papercraft model.

Copyright (C) 1995, 1996 Anthony D. Martin
|
|
Usage: /usr/share/inkscape/extensions/mightyscape-1.X/extensions/fablabchemnitz/papercraft/.libs/admesh [OPTION]... file
|
|
|
|
--x-rotate=angle Rotate CCW about x-axis by angle degrees
|
|
--y-rotate=angle Rotate CCW about y-axis by angle degrees
|
|
--z-rotate=angle Rotate CCW about z-axis by angle degrees
|
|
--xy-mirror Mirror about the xy plane
|
|
--yz-mirror Mirror about the yz plane
|
|
--xz-mirror Mirror about the xz plane
|
|
--scale=factor Scale the file by factor (multiply by factor)
|
|
--scale-xyz=x,y,z Scale the file by a non uniform factor
|
|
--translate=x,y,z Translate the file to x, y, and z
|
|
--merge=name Merge file called name with input file
|
|
-e, --exact Only check for perfectly matched edges
|
|
-n, --nearby Find and connect nearby facets. Correct bad facets
|
|
-t, --tolerance=tol Initial tolerance to use for nearby check = tol
|
|
-i, --iterations=i Number of iterations for nearby check = i
|
|
-m, --increment=inc Amount to increment tolerance after iteration=inc
|
|
-u, --remove-unconnected Remove facets that have 0 neighbors
|
|
-f, --fill-holes Add facets to fill holes
|
|
-d, --normal-directions Check and fix direction of normals(ie cw, ccw)
|
|
--reverse-all Reverse the directions of all facets and normals
|
|
-v, --normal-values Check and fix normal values
|
|
-c, --no-check Don't do any check on input file
|
|
-b, --write-binary-stl=name Output a binary STL file called name
|
|
-a, --write-ascii-stl=name Output an ascii STL file called name
|
|
--write-off=name Output a Geomview OFF format file called name
|
|
--write-dxf=name Output a DXF format file called name
|
|
--write-vrml=name Output a VRML format file called name
|
|
--help Display this help and exit
|
|
--version Output version information and exit
|
|
|
|
The functions are executed in the same order as the options shown here.
|
|
So check here to find what happens if, for example, --translate and --merge
|
|
options are specified together. The order of the options specified on the
|
|
command line is not important.
|
|
|
|
NOTE: If admesh on linux fails just run "make clean && make" to re-create the executable. There error could be like
|
|
"papercraft_unfold/admesh/linux/.libs/admesh: error while loading shared libraries: libadmesh.so.1: cannot open shared object file: No such file or directory"
|
|
admesh is sensible for moving from one dir to another
