Extending an existing STL file ??

I have modified a few existing STL files by importing them and then
adding/subtracting with SCAD and it's worked out well :-)

However, I now need to modify one by making the center 10% portion of a
hollow shape longer. The rest needs to remain the same so a simple
scaling operation wont work.

Can anyone suggest the best approach to this problem ? My initial
reaction is to cut it into 3, stretch the middle bit and stick it all
back together but I wonder if there is a better way.

TIA Dave

Hi Dave,

I'm struggling to envisage exactly what you want to do, and the answer will depend on the actual object.

But, if the object edges at the middle are parallel to the axis you want it to expand in, then just union the original object with a copy that has been offset by the desired amount.
