STL export misses subtraction of extruded text #200

Tried to export to STL model of label table with carved (by subtraction) text. While model in viewport and height-map image both has carved text, the STL-exported model looks like flat table without carving.

Zipped graph file, height map and zipped STL are attached.

label.sb.txt height-map antimony.stl.zip

Environment: Binary installation on Mac OS Mojave. Release: 0.9.3 Git revision: 020910c

Have you tried increasing the mesh resolution? I'd be suspicious that the thin text is just missed by the meshing sampling grid.

@mkeeter, please disregard this report. Reason is simple: Mac's Preview and some online STL viewers are rubbish without proper shading :) Even with minimal resolution (1 voxel per unit) text do appear as expected and visible in better viewers.

Btw, your viewer works fine!
