How to change dimension ?

[Max58]

Hello,
I'm trying to model a Yagi antenna but I find difficult to make the element the right size. I mean I want to resize only lenght and not the diameter of element. Which tool can i use ? In which way ?

Most likely you can use Push/Pull to move the end of the cylinder the right distance. It would be easier to give you an exact answer if you share the SketchUp file and tell us what you want to change the length to.

I would use the 'Move'tool on a (selection of) rod(s) that need to be moved.
You can move the rod from its current position to where you create a guide (parallel to the rod).
