positioning asemblies
positioning asemblies
(OP)
Good morning All,
We have a number of assemblies such as cylinders, press units, pick and place units, etc. which are mated to allow movement to the their respective extreme positions generally using coincident mates. Configurations provide the options for these positions and work well.
In cases where an intermediate position needs to be shown i.e. somewhere within the defined extremes of position, I am trying a limit mate to allow free movement within the mechanical limits of the assembly. These assemblies are brought into the next level as subs with the "free" configuration selected there and flexible. I then use a set of position control planes to define tooling positions, and mate the freely configured sub assembly to these control planes. Sometimes it will work, but mostly this method produces mate errors.
If the desired tooling positions are at the extremes of the sub, the appropriate configuration is selected with no problems. It is only when I need the intermediate position when I have a problem. Since the subs are standards I do not what to create a new sub for any change in positioning, nor add configurations for the unlimited number of possible positions.
Any thoughts on how to produce any given position of a sub assembly controlled from the top level? Thanks

You can also use the tick box on the mate properties labeled "Use for positioning only" to move the part held by the limit mate to the required position.

Needed to supress limit mate.
