Ok so ive had some excellent help of this forum over the last few weeks. im hoping its not going to stop here!

See Fig 1.


A sketch split into 3 bodies, i can extrude from this 3 separate part bodies in a number of ways (for example)


1, to make a extrusion using a "area"


2, a derived sketch  using convert entities then use the sketch of that to make the extrusions


there are also a few other ways.




so basically i end up with 3 bodies driven by the top sketch - see fig 2.


Now i can change the shape of these see fig 3


which works fine


but if i change any of the lines see fig 4


then fig 5 happens.


anyone got any solution to this?


i have one "work around" but im hoping someone has an actual solution.


thanks Joe.
