Vector Shapes

You can mark up the heightfield with polyline and spline shapes, as a visualization aid or as a modeling assist.

Use vector shapes to annotate, to add local texture detail, and to easily fill areas with objects. Illustrator-style controls let you easily create markers (points), lines, polygons, circles and arbitrary curves. You can also obtain raster selection masks from vector shapes for precision modeling. Elevated shapes let you work with contour lines and quickly create heightfield formations. Import shapes from GDAL-supported formats and Adobe Illustrator, and export to DXF, Illustrator, and to SVG.
