SPEED — draw the jump before you build it

The odd one out, and proudly so: give SPEED an initial velocity (km/h), a take-off angle and a start point, and it draws the projectile’s trajectory as a spline in your drawing — then prints the jump length and height in metres.

Built for dirt-jump design; works for anything that leaves the ground at an angle.

How to use it

1. Unzip, then load the .lsp with APPLOAD.
2. Type SPEED.
3. Enter velocity (km/h), take-off angle, and pick the start point.
4. Read the jump length and height on the command line.

From the same workshop — watch what the paid add-ons do

Divide Area Split any closed shape into pieces of equal area – by number, by distance, a set area or a free cut. See Divide Area — $21.90

Area Measure Measure closed shapes in any unit, number them, and get a totalled area table – annotative text supported. See Area Measure — $21.90

Voronoi Generator Fill any closed polyline with Voronoi cells – exact spacing, edge distance and rounding, live preview. See Voronoi Generator — $24.90
