Collision detection in Alibre Motion
Alibre motion needs to have a collision detectection feature where a part in motion is arrested wehn it contacts another part. This feature should also be able to take into account a part in motion being acted upon by a return spring and being acted upon or acting upon a camming feature.

Planned for Motion 2.0:
*Motor Limits
*2D Curve Contact Detection (tentative)

Alibre should allow parts to slide along a track or a guide and follow that guide thru a radius and up a ramp, instead of constraining to one degree of motion in both design and motion windows.
Also parts should be able to be made solid so to speak, so two metal parts cannot pass thru each other, but stop instead.

I need collision detection in assembly mode without having to go into Motion mode. It's useful for a slower computer and eliminates having to load into Motion just for analyzing a few simple parts.

I am doing a lot of head scratching around the motion of a ratchet and pawl. Making a constraint where a point could be created that can mate with a face along the edges would make this work as the point would just stick to the closest instance of edge/face it can reach. Alas when I try this, i become overconstrained..... collision detection then :)

I don´t want to start every time motion to demonstrate a movement. Another feature I am missing in motion is the compression of a spring. Perhaps it can be realized with a physics engine like bullet.

I agree with Stephane, collision detection would be very valuable when manually moving parts in an assembly. Most often a new design demonstration will take place by simply draging parts and it would be useful if parts stopped at the end of their designed travel limits. Alibre Motion is mostly used when a recorded demonstration is required, or when it is important to involve properties such as mass and gravity effects.

i added a "physic behaviour" suggestion, because i think users also want collision detection while manually moving a part in assembly workspace. I prefere to add my vote to a more generic feature, not just a AMotion feature. Generic Physic behaviour can also serve AMotion.
