Learning Curve's A Bit Bumpy...
-----------------------------------
Spent the day trying work-arounds for the 3D Boolean problem. Sadly, anything derived from a door model soon locked-up. I honed the work-flow, but only got a migraine out of it...

So, forget that approach, revert to 'first principles'. I crafted my 'arch-ery' by months of trial, error and basic geometry. Each arch began as a polygonal prism with the same number of sides as inches to span. I used the doorway as a 'jig' to draw an identical but fresh polygon, 3D sliced it level, added a block to cut out the rest...

A grim hour later, I realised that *3D Adding* these two parts was a mistake, as it began the count-down to a Boolean lock-up. I then discovered that 'bundling' the separate parts as a library object prevented their combined use for Booleans. I had to 'explode' the pair prior to use, apply them individually...

Good news, they worked repeatedly !!
