<p>

<p>An <a href="bracket.$TEMPL::PL"><b>introductory tutorial</b></a> is available,

in which we draw the same part that is shown in the demo video. This

covers most of the basic features of SolveSpace, including sketches,

constraints, extrusions, and Boolean operations.</p>

</a>

</div>

<p>An <a href="box.$TEMPL::PL"><b>assembly tutorial</b></a>, in which we combine

multiple parts into a parametric assembly. We use constraints to define

the positions and orientations of the parts within the assembly.

This means that we can

modify the parts and regenerate the assembly, and the parts will remain

assembled in the desired configuration.</p>

</a>

</div>

<p>A <a href="constraints.$TEMPL::PL"><b>tutorial on constraints</b></a>. We look

more closely at the geometric meaning of constraints in SolveSpace,

and the ways that an incorrectly-constrained sketch will fail. We

constrain a simple sketch in several different ways, and use the tools

that SolveSpace provides to debug after overconstraining it. We also

look at sketches with multiple solutions, and constraints both in 3d and

projected into a workplane.</p>

</a>

</div>

<p>A <a href="linkage.$TEMPL::PL"><b>tutorial on linkages</b></a>. We use

geometric constraints to model a planar linkage; we then displace one

of the links, and let the constraint solver calculate the resulting

geometry. We use this to plot the coupler curves of the linkage, and

to animate a solid model attached to our linkage's skeleton. We also

look at other kinds of linkages, with joints other than simple pin

joints. </p>

</a>

</div>

<p>A <a href="2d.$TEMPL::PL"><b>2d drawing tutorial</b></a>. We use SolveSpace

to draw a pure 2d part. So we start with a contour, and specify it using

dimensions and constraints. We also use special tools to split lines and

curves where they intersect, and trim them against each other, and to

round sharp corners. After drawing the part, we place cosmetic dimensions

on the geometry, and export a human-readable dimensioned drawing.</p>

some additional tutorials</a></b> (external site).

<p>And video tutorials are available for a range of topics. These

tutorials were recorded using an earlier version of SolveSpace, so

some slight differences in the user interface may be visible.</p>

</a>

</video>

The introductory tutorial. We review the basic user interface,

and draw a simple 2d part. Covers rectangles, symmetry constraints,

distance/length constraints, and equal length constraints.

<source src="vids/angle-bracket.mp4" type="video/mp4"

onerror="videoFallback(parentNode)">

</a>

</video>

We draw a slightly more complex part, by combining multiple

extrusions. Introduces workplanes and Boolean ops, and several

new constraints.

</video>

We look at constraints in more detail. Covers inconsistent and

nonconverging sketches (two common error conditions), projected

constraints in 3d, reference dimensions, and construction

geometry.

poster="pics/vid-step-and-repeat.png">

<source src="vids/step-and-repeat.mp4" type="video/mp4"

onerror="videoFallback(parentNode)">

</a>

</video>

We look at step and repeat; this takes entities, and copies

them multiple times along a line (translating) or the arc of a

circle (rotating). The details of the step are specified using

constraints.

</div>

</video>

We build an assembly from multiple parts. The positions and

orientations of the parts are enforced using constraints. We

run a computed intersection check, to verify that the parts

don't interfere. We then go back and modify one of the parts,

and observe that the changes propagate into the assembly.

</a>

</video>

We draw linkages and other mechanisms, and simulate their

operation using the constraint solver. The trajectory of certain

points on the linkage is traced and exported. We also attach a

linkage to a solid model, and animate the solid model by dragging

the linkage.
