Link values of different components in an assembly
Link values of different components in an assembly
(OP)
I am trying to link two dimensions that are in 2 different components in an assembly. I tried linking them but it doesn't work. Does linking values only works if I link 2 or more values in the same sketch?

You will have to use equations instead.

RE: Link values of different components in an assembly
Sorry Scott, I have to disagree ... Equations can & (as far as I know) always have been able to use a dimension of one part to control a dimension of another part in an assy.
Try it and see with a simple Width@... = Length@...
RE: Link values of different components in an assembly
I'm pretty sure there was a time when you couldn't control a part like that, but then again I might be wrong.
I was always told this for years. But things change and sometimes it's hard to keep up. Thanks for pointing that out CBL.

RE: Link values of different components in an assembly
For a simple example.
I have two parts in an assembly called 'Box' and 'cylinder'. The length of the box is set to equal the length of the cylinder by an equation. However, If I then create a number of configurations of the cylinder (controlling its length) and then change the configuration of the cylinder used in the assembly, the square will not update (or at least I can't get it to) - Has anyone come across this before? Anyway around it?

RE: Link values of different components in an assembly
I have a cylinder with wall thickness 'T' and I want this to stay equal to the side of cube 's'. The cube has numerous configurations. Lets say I need to control this by an equation in the assembly. Here is what I did. In assembly mode select sketch and select a face of the cube as the sketch plane. Select an edge of the cube and then convert entities. Now also dimension this line. You will get the overdefined warning. Right click on the dimension and select 'Driven'. That will remove the error.I will call this dimension 'd' from now on.
Now you have a dimension inside the assembly that will change as the cube component configuration changes, as will the driven dimension. You can now use dimension 'd' to define dimension 'T' (i.e. set T = d). The only draw back is that you will end up with a load of 'dumb' sketches in your assembly. The other problem is that you cannot do this for things like quantities of features in patterns. I wouldn't recommend as a design methodology but I find it neccessary in one or two eqn's within my assembly.
