what's really needed:
- line-styles, line-colors and line-weights
- workplanes for dimensioning (now it's somewhere in space speaking about dimensioning a layout/plans/sections) and annotations (text without leader in certain workplane)
- hatches of cutted components coresponding material types
- improved relation with LO: now to print SU model in LO make no sence - terible quality, or vector rendering option shall be reconsidered (probably this is an improvement for LO)
