Using bottom up assembly, how do I adjust a part to fit another part.

I have imported some predesigned parts, and want them in my assembly, but have a question. Lets say I have 2 imported parts that are connected by a pipe. I do not know how long the pipe is, but I need the 2 parts to be 1m apart based on a certain point on the imported parts. How would I do this?

@brian_wagener, I don't think mate connectors are even necessary in this example. Mate connectors are helpful for (wait for it) assembly mates. In your case, you can get away with designing your whole assembly in part studio since there is no relative motion between parts. Thus, no mate connectors required. Take a look at my example. You can change the #Size variable, and the position of the derived part and connecting tubes updates accordingly.
Bottom up test
If you did have to use any of the parts in an assembly, just make sure to add the mate connectors after you've done any necessary transformation. That should yield robust, non-buggy results.5

Obviously there are many ways to achieve what you are looking for. I would recommend inserting your imported parts as derived parts and transforming with mate connectors to set the 1m dimension. Then you can build your pipe to fit. Also if the 1m dimension changes in the future....the pipe could update to match the new dimension. Additionally if one of the fittings changes in the future....you can just version up and remove the derived fitting and insert the new one.
It is a little tough to give advice without actually seeing what you are doing and the parts.
You can create a public document and Im sure multiple people here will jump in and help
I have made many things before with onshape, but this is the first time with multiple parts, and having problems figuring anything out. If you look at the linked project, on the part studio page, you see 2 parts that I want to connect with the pipe. I have a sketch, that I want to align the vertex of the sketch with the center of the circle on the parts. I tried adding the parts as derived, but couldn't even figure out how to move them.
I think you may be seeing the mate connector from the derived part in its original position.
Look in the feature tree on the left side and find the derived feature....hide it. See if that makes the mate connector go away.
I find it weird that mate connectors from derived parts stay in the original position after transforming.
