I just tested with CatProduct, so I confirm that you can open them (even if there is an error message related to the lack of license). It only takes the standard license.
In SolidWorks, the only way would be to do point-to-point measurement, but in any case you have to select the entities sequentially. If the measurement is still made from a " fixed " entity, you can always deselect the last entity and then select the next one. Otherwise, once the measurement has been taken, right-click and then " Cancel selections "
