Trim fuselage with scaled wing . (Scale wing geometry for about 30 percent). Hide wing we will not use it now. Fig. 76 – Trimmed fuselage geometry in UG NX4 Insert ZY, DATUM PLANES where we will have fuselage frames. It is important to remember that too many fuselage frames make geometry hard to export to <strong>PANUKL</strong>. If you have time and fast CPU insert as many as you want . Fig. 77 – Fuselage half with DATUM PLANES in UG NX4 66
Remember: don’t insert DATUM PLANES where wing trailing & leading edge intersect fuselage. Fig. 78 – Important note about inserting DATUM PLANES for frames, UG NX4 Use INTERSECTION CURVE (UG NX4) function to create intersection curves where we have inserted DATUMS. Additionally add curves where the model was trimmed with wing. We have made our fuselage frames. Fig. 79 – Fuselage intersection curves – fuselage frames, UG NX4 Now we need to create points on our frames – use POINT SET/POINTS ON CURVE function. 67
