First this is not a stupid question it’s a sign that you are a careful modeler.

This used to be a very common question when most of the models were hand drawn and the lines were thick. I would suggest that you make your judgment based on the thickness of the lines. Newer models designed in the last six or seven years have very fine lines often less then the thickness of the paper the model is printed on. On these fine lines I would cut to the middle of the line and dry fit the parts, you may have to trim or sand the part to fit. After you assemble a few parts you will get the feel of how the designer wanted the lines cut. I have found that on the Modelik and Halinski kits you want to cut to the inside of the line. GPM seems to vary but generally cutting to the mid to inside works well.

Bottom line cut the part over size and fit the parts this is a little more work but you will get better fits.
