Thanks Michael
I find the history function when sweeping a profile then fine tuning it after generation invaluable.
I typically would array the stone solids and beads and array them along a shoulder profile and once correct don't change it, perhaps a history dump button or option on the history could get rid of the back history and reduce file size .
I see your point that saving all that data will generate large file sizes, my pc seems to handle large files with over 2000 solids (a lot of them with fillets ) Ok , some of the stl output files are in the 100's of mb
Feel free to add history on arrays to my wish list :) oh and the variable radius fillets (like the 2 distance chamfer) :) I realise thats a hard one also

perhaps an on off toggle in the options for those not wanting it rather than mucking around with the side pane buttons

thanks
