RCM on drawing charges paid

XYZ (Belgium) had placed an order on PQR(India)for supply of Machinery. The drawings relating to these Machinery was supplied by XYZ to PQR and issued an Invoice on PQR towards recovery of Drawing charges. Is PQR required to pay GST under reverse charge on the amount paid to XYZ? In my view, it will fall under Section 13(2) of IGST Act and therefore, PQR will be liable to pay GST under reverse charge. Views of the experts please.
