Flash-LGS :: Samples

Stroke engine

This sketch shows kinematics of common stroke engine mechanism. By moving a piston (marked by circle) to appropriate position along axis you're force LGS-engine to calculate positions and angles for connecting-rod and crankshaft.

Landing gear

Sample shows kinematics of retractable ski-landing gear of prospective spacecraft, which lands on chutes.

3D model of landing gear (blue box - gear niche)

By moving ski platform to gear open, closed and intermediate position you force LGS to calculate the angle and length (i.e. stroke length) of hydro-cylinder.

Cube sketch

This example shows how sketch, initially drawn not quite precisely is converted to accurate shape by applying appropriate constrains to its elements.

There are three entries in Flash-LGS samples list:

Cube-sketch - an initial drawing
Cube-sketch-constrains - drawing with constrains applied
Cube-sketch-complete - final drawing with complete solution

Bike

A sample shows construction of parameterized bicycle frame.

There are two samples, showing stages of design:

Bike-sketch - initial drawing

Bike-constrains - all parameters set and solution is calculated.

By changing some of constrains in the list you allowed to reconstruct complete wire-frame. For example - changing one of the wheels radius follows to changing radius of the second wheel too. Changing the angle or length of the main seat tube (in this particular sample set to 70) forces complete bike frame tubes rearrangement.
