Not all vector programs are the same. Concepts specializes in making your vectors appear like traditional raster tools for a natural feel, which other vector-based applications do not support.
If you are creating a project that will be used in other vector-based apps, and intend to export via SVG, DXF (AutoCAD) or PDF (Simplified Paths, Vector, Adobe), note that only the vectors and not the textures will transfer. Use the Wire and Fixed Width tools for drawing.
This includes our Hard and Soft Masks - they appear as white lines in other apps. Use the Slice tool to edit and erase line work in your drawings instead.
