New sketch features:
* New groups, revolution and helical extrusion.
* Extrude, lathe, translate and rotate groups can use the "assembly"
boolean operation, to increase performance.
* The solid model of extrude and lathe groups can be suppressed,
@ -52,6 +53,7 @@ New export/import features:
exported. This format allows to easily hack on triangle mesh data created
in SolveSpace, supports colour information and is more space efficient than
most other formats.
* VRML (WRL) triangle meshes can now be exported, useful for e.g. [KiCAD](http://kicad.org).
* Export 2d section: custom styled entities that lie in the same
plane as the exported section are included.
@ -68,6 +70,10 @@ New measurement/analysis features:
* New command for measuring center of mass, with live updates as the sketch
changes, "Analyze → Center of Mass".
* New option for displaying areas of closed contours.
* When calculating volume of the mesh, volume of the solid from the current
group is now shown alongside total volume of all solids.
* When calculating area, and faces are selected, calculate area of those faces
instead of the closed contour in the sketch.
* When selecting a point and a line, projected distance to current
workplane is displayed.

summary: Parametric 2d/3d CAD

description: |
SOLVESPACE is a free (GPLv3) parametric 3d CAD tool.
Applications include
* modeling 3d parts — draw with extrudes, revolves, and Boolean (union / difference) operations
* modeling 2d parts — draw the part as a single section, and export DXF, PDF, SVG; use 3d assembly to verify fit
* 3d-printed parts — export the STL or other triangle mesh expected by most 3d printers
* preparing CAM data — export 2d vector art for a waterjet machine or laser cutter; or generate STEP or STL, for import into third-party CAM software for machining
* mechanism design — use the constraint solver to simulate planar or spatial linkages, with pin, ball, or slide joints
* plane and solid geometry — replace hand-solved trigonometry and spreadsheets with a live dimensioned drawing
