Construct a Nominal plane

I have a bent tube and I want to construct a nominal plane at one end of the pipe so I can intersect a cylinder to it, I have the XYZIJK info but I am unsure of the best way to do this, should it be before or after my alignment, what type of plane do I use? I have cad.

Use a generic plane. Is this a measured plane? Is that where you're getting the XYZ and IJKs? If it is then you can do something like this.

T_CYL=FEAT/CONTACT/CYLINDER,CARTESIAN,OUT,LEAST_SQR
            THEO/<1.151,-4.288,-10.45>,<-0.6327551,-0.774329,-0.0059655>,0.25,0.44

            START ANG=90,END ANG=-90
            DIRECTION=CW
            ANGLE VEC=<0,0,1>

            SHOW CONTACT PARAMETERS=YES
              NUMHITS=3,NUMLEVELS=3,DEPTH=1.42,END OFFSET=-0.58,PITCH=0
              SAMPLE HITS=0,INIT SAMPLE HITS=3,SPACER=0
              AVOIDANCE MOVE=NO,DISTANCE=1
              FIND HOLE=DISABLED,ONERROR=NO,READ POS=NO
            SHOW HITS=NO
T_NM_PL=GENERIC/PLANE,DEPENDENT,CARTESIAN,$
            NOM/XYZ,<T_CYL.X.THEO,T_CYL.Y.THEO,T_CYL.Z.THEO>,$
            MEAS/XYZ,<T_CYL.X.MEAS,T_CYL.Y.MEAS,T_CYL.Z.MEAS>,$
            NOM/IJK,<T_CYL.I.THEO,T_CYL.J.THEO,T_CYL.K.THEO>,$
            MEAS/IJK,<T_CYL.I.MEAS,T_CYL.J.MEAS,T_CYL.K.MEAS>

If you ONLY want a nominal plane then replace the .MEAS with .THEO and the plane will always be at the nominal location of whatever feature you choose to load your generic plane with.
