awsome, yea, i hadnt noticed why it seemed to crash into something when i had the wheel close

PS im just uploading the file so i can easily transfer it to my other PC later on

Scissor3.1.skp

hey, im just in the SPhysics picture, so ill say what ive learned so far

i belive you want to make an object stay in the air without falling?
is so, i there is a setting to reduce gravity to 0 OR you can group said object and right click it> sketchyphysics>state>static; again, i tell you im a beginner so ther might be a better way to do so....

ok, good that you havent got back to me, i figured it out, i hadnt either grouped or connected the motor, but now, i belive its better if i use a servo, so i changed it.

but now, when it turns and pushes, the scissors move off track, i tried placing a slider at the end, but it wont recognize the servo if i do, so, now, i ask you

i hope im not being too buggy here, this is the first time ive used SPhysics.

Scissor3.1.skp

ok, so here i am again, i think i got the hang of the hinges, but now, i cant get the motor to work
i began from scratch, and the model is 10x to real world size (so the hinge animations dont take up so much space [10cm=1cm])

Scissor3.skp

ok, i had a bit of time to mess around, and i made this:Scissor2.skp , so, i cant make the scissors follow the track, and the first one, does not contract completely, i dont know why, i know i must be doing somthing wrong in a very basic level, but please, bear with me u.u, the idea is that the beam with the piston (the one alinged to the red axis) conects to a gear, and works kinda like a piston (something like this:

)
so that for each half turn, it will expand completely, and another half turn will contract it.....

hpnisse, thanks, you have no idea of how much help you just gave me
right now, i dont have time to get into this, but i will shure look into it later on today, or possibly until tomorrow. you just grouped it as in normal sketchuo group, or as in sketchyphysics "join"? nevermind, when i examine your model i will porbably answer my own questions, if i dont, i will get back to you.

one thing thou, is there a way to make the animation more... solid? without the spring action it has?

Hey guys, ive been trying to figure out sketchyphysics for all day now, and i barely got the hinge tool. so, ive decided to ask for help: ive been trying to build a scissor thing, i believe its the mechanism pantoghraphs use, im trying to create it, so i can make easy calculations (the dimenssions of the peices so i can extend it _ length) well, i just cant manage it, i cant get the hinges to move, i tried building it up based on LilDood's model, (a forklift, as it seem) and just now, ive given up U.U

ive attached the file, (i think) so you guys can see where im wrong, i dont care about the dimenssions at the time, right now, i just wanna know how its done.....

this is my file

this is LilDood's File NOT mine
