Hinge Motion

[prestonjharris09]

Hello everyone. I am a freshman in high school, and I am building an assembly that includes a hinge. I used a Youtube tutorial to build it, but I am having trouble making it move. I am an inventor beginner, so please be patient with me. I have attached my assembly file. Can someone see what I am doing wrong?

Hi, there is no file attached. Also if you attach an assembly you also need to attach the parts. 

Do you need it to move automatically or by dragging?

My bad.  I attached the assembly file to the original post. Here are the parts. I need it to move by dragging. Thank you so much, if you can figure it out let me know what I am doing wrong.

There's nothing wrong with what you've done constraint wise, you just need to ground one of the parts or everything will move together. Right click one of the parts and choose 'grounded.'

I'm not sure what they're teaching you, but an insert constraint would be quicker for the pin.

I also find 'place and ground first component at origin useful in application options.
