johnnyshield, the file you are importing does not have a defined scale in the Paper Space. LayOut needs this information to import the data correctly at the right scale. So in acad or other, define the scale of the Model Space, you can then adjust the viewport to crop the area you would like, save, then import into LayOut.
By default a cad file will have a Model and a Paper Space so LayOut will see that a Paper Space is available to import but if the the viewport does not have a scale defined LayOut will not import it.
