More types of Assembly Constraints
Distance limits; Angle limits; Gears; Cams etc.

There are a lot of different enhancements discussed on this ticket. Many of them (rotational mechanisms for gears, cams, 2d contact detection – to name a few) will be included in the Motion 2.0 update.

"IMO this needs to be included in normal AD assemblies not just Motion 2 . Assemblies could then operated manually within the Assembly workspace and then automatically with motors etc in Motion."
By design, I think it "has" to work first in the normal workspace. Let us hope!

From vids i've seen this seems to happens in SW without going into motion type program.

Fully agree with Justin's comment/idea posted on Feb. 10th 2011

This has been a long time in comming; its greatly needed. Alibre Motion as it is now, is much too limited!

mate to curved surfaces
collision detection with the option to allow solids to pass through each other or not

I think that constraining the range of motion of a part within an assembly or even within a drawing (though latter is less important) would be useful and, in my mind, obvious.

I would argue that the issue is LIMITS (mate, align, offset, etc.) to some constraints as well as new types of constraints (helical from a basis for screw-type actuators, etc). The "issue" is to make our assemblies respond to "inputs" (assuming cursor-feed for now) in a manner more accurately representing their real-world response(s).

How about this ..seems to me like the math would be simple and would solve some of the problems i have using cylinders. a mate contstraint for object 1 (point,surface,plane) between 2(p,s,p) and 3(p,s,p) wouldn't that serve as a defacto range for linear motion? I would assume this would be a last set up constraint so that only one axis is possible with existing constraints. Hmm... add the ability to add offsets and that would take care of short strokes also.

You can draw a gear but it will not work like a gear... Alibre... Please make this software of yours except real life intelligence to understand how a real part would act on another part. (gears, Pulleys). Now coming up to 2rys now... Since and no Advertisement or new about this.. We(customers) love you software but it needs to be capable to do the work, and not just look like it can.

More constraints, particularly for every kind of cam and gears!

Contraints for linear cam, gears

I spend alot of time centering a part between 2 other parts (via mate + offset). SW can do this w/ 1 constraint.

more assembly constraints, like
a limit distance for linear actuators
gear and pulley constraints
and even a gear/sprocket/pulleys generator, along with a belt/chain generator, and a easy way to time all parts to the belts/chain, and be able to do this all in the assembly level, that way when you open motion there is only one motor that has to be applied, not sure if thats possible but sure would be exciting and not to mention incredibly fast to put a complex model together. -

I need a proximity restraint for relative longitudinal motion. To further explain, as when one part is moved and draws near a collar which will then cause a second part to move as well. Longitudinal and rotational proximity constraints would certainly be helpful in complex designs.

Probably the most useful constraints would be gear-train and belt/pulley with collision detection. The implementaion is probably compute intensive, but that could be acceptable today, given high-performance multi-core CPUs, if coded for multi-threading and it follows through to Motion.

I would like to have constraint to use for things moving on trail or similar and angle between two values. These both are needed for example to create working rauvolet cabinet. I would also like to have allow / disallow collision while moving to easily check movement limits. Now I have to zoom very close to see when collision happens and it's impossible to just shut down door or drawer because it moves through.

A closely related feature that would be very welcome is a centred rectangle tool; instead of drawing a rectangle and then use the symetric contrain twice, a new rectangle tool that starts at the centre point and then moves to one corner and automatically inserts the symetric constraints would save me time for every new part I make. (Solid W***s does this nicely).

Allow constraining to sketch features (in the assembly) such as lines points etc.
As Steve said, a simple concentric limit would be great but the other sugestions are worthwhile as well.

A Constrait to position a part in the middle between two selected planes or surfaces! this constrait should support also round objects!!

I would like to have the possibility to constrain onto curved surfaces like O-rings. Now you must use the reference geometry, but this is not always possible. It would save a lot of time when the surfaces of the ring and chamber could be used for constaining. Also when the central axis of holes or revolutions can be displayed and used for constaining like in Solidworks.
