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.
