<label appearance="header">Slic3r STL Input</label>
|
||||
<label>This extension is highly based on the work of Jürgen Weigert. It projects an STL file on the X-Y plane by cutting the objects into "slices". Each "slice" is a group of polygons, with a label indicating it's z position. The polygons are converted to paths for better editing in inkscape. Use Object -> Rows & Columns to distribute the slices in a grid. Possible input files are STL, Wavefront OBJ, PLY and OFF.</label>
