looking at this section of drawing there has been one little mistake made in assembly

the numbers that are marked on the custom panels of the facets (for identification during assembly) are supposed to be facing outwards (the back face of the formwork) when put together. however it was decided for mainly aesthetic reasons (there was a sneaking suspicion that the 50:50 choice would come out wrong) to put the numbers on the casting face of the formwork.

which can be resolved in a few ways....

1. rebuild every facet assembled the other way round... ie put the backing support struts on the other side

2. deal with the matter and have the cast inside-out model and have the formwork semi attached

3. deal with the matter and have the cast inside-out model and then reassemble the formwork the right way, so that the numbered face is on the outside and not the inside which (as 3.a) could potentially be poured the right way, however this will leave the supporting struts buried in the plaster, no doubt destroying the face of the plaster when the face pieces are removed.

so in all option 3 seems to be the one to aim for, a little wrong. but still good. will still do the intended job.

numbered specials on casting face potentially printing onto cast plaster (in negative)

supporting struts on the unnumbered side (currently assembled)

move the supporting struts to the opposite face (essentially requiring all the assembled pieces to be reassembled (option 1))

assembling piece number 1(actually the second)

why did i think this would be a good idea?

ouch... manually nesting all these pieces for lazercutting.

the reason it had to be manually laid out is that the nesting plugin wasn't able to cope with as many pieces

tessalation was best achieved by retaining the plywood sheet orientation; and not using a randomised approach.

the text probably needs to be increased in size a couple of times.

450x750 1:20 automatic spacing vs manual spacing

alignment script corrected

click together profiles for all components assigned

top left panels omitted inadvertently to be replaced.

still the start of the panels could be optimised, but to push the scripts to achieve that would take till 5 tomorow morning, and the lazercutter wants feeding!

the numbers still need to be assigned.

this example didn't optimise the rotation angle of the plywood panels

the green pieces are the standard 4 by 8 formwork panels, the blue pieces are the large size cut formwork panels

and the red pieces are the small cut formwork panels(these ones arent big enough to take a reference number at 1:20, and so must be dealt with separately

it is big.. these dimensions are in metres
