SOLVESPACE -- parametric 2d/3d CAD

SOLVESPACE -- parametric 2d/3d CAD

Postby halfnormal » Wed Jan 29, 2014 7:01 am

I found this program while cruising the internet on the hunt for CNC info. What is most interesting is that it is a single file program with no installation needed. Looks like it would work well on older machines running older versions of windows. Best of all it is freeware and open source.
Here is a description of the software from the website;

SOLVESPACE is a parametric 3d CAD program. 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

FEATURES

Sketch sections using
lines, rectangles, datum lines and points
circles, arcs of a circle, datum circles
cubic Bezier segments, C2 interpolating splines
text in a TrueType font, exportable as vectors
trims to split lines and curves where they intersect
tangent arcs, to fillet lines and curves
line styles for stroke color, stroke width, fill color
adjustable snap grid, for entities and text
menu item, keyboard shortcut, or toolbar
cut and paste, in plane and from workplane to workplane
background image with specified scale, for ease of tracing
3Dconnexion six degree of freedom controllers

Constraints and dimensions on
distance (or line length), point-line distance, diameter
projected distance, along a line or vector
angle, curve-to-curve tangency, parallel, perpendicular
horizontal, vertical
equal length, equal angle, equal radius, length ratio
line length equals arc length
point on line, point on circle, point on point, point on face
point at midpoint of line, line's midpoint on plane
points (or line) symmetric about line or plane
2d (projected into specified plane) and 3d geometry
lengths in metric or inch units
lengths entered as arithmetic expressions (32.6 + 5/25.4)

Build solid model with
extruded or lathed (solid of revolution) sketch
Boolean operations: union (add material), difference (remove material)
parametric step and repeat (pattern), rotating or translating
operations performed on either meshes or NURBS surfaces

Parametric and associative assembly
import parts and drag them with six degrees of freedom
import mirrored or with arbitrary scale
place parts in assembly using constraints
import surfaces, and merge them using Boolean operations
import lines and curves, for 2d work or solid operations later
changes in parts propagate automatically into assembly

Analyze with
measurements on a part or assembly (of point coordinates, line length, point-point distance, point-face distance, projected distance, face-face angle, point-line distance)
path traced by mechanism, exportable into a spreadsheet
area of a plane sketch, volume of a solid shell
degrees-of-freedom check to show unconstrained points in sketch
interference check for assemblies
"STL check" (vertex-to-vertex and not self-intersecting) for mesh

Export
2d vector drawing as DXF, EPS, PDF, SVG, HPGL, STEP
toolpath as G code
as either piecewise linear segments or exact curves
wireframe model, hidden-line removed model, vector shaded surfaces
isometric view, orthogonal view, user-specified other view
section of solid model
with cutter radius compensation
with adjustable canvas size
3d wireframe as DXF, STEP
triangle mesh as STL, Wavefront OBJ
NURBS surfaces as STEP
shaded view as bitmap

Shouldn't've been that far. It is on the wiki:

http://www.shapeoko.com/wiki/index.php/CAD#3D

3D modeling (Opensource) SolveSpace Parametric 3D CAD program for Windows. See also its 2D predecessor, SketchFlat.

I did update the listing to note that it's now open source, do you think more should be added?

I did a quick search on the forums but did not think to search the wiki. Thanks for catching that!

I think it is good as it is. People can go to the site and learn more if interested.
