small niggle follows:

floor construction say 150mm concrete slab on 150 hardcore layer with the concrete slab having an edge thickening. once a section has been cut the thickening positions itself to the hardcore rather than the concrete slab. although the thickening can be moved with an offset the hardcore runs straight through the upstand (boo). i can manually cut out the hardcore on the sections but this all seems rather manual/a fudge. any bright ideas from any bright sparks?

Wow - you made me smile.  Trying to understand your slang (terminology) - I hope someone else from GB can answer this because I don't understand words like niggle (problem?) hardcore ? (don't have a clue) upstand (boo) ... << what :->

 

I am assuming that your floor is multilayer with the hardcore being something like gravel? 

 

Maybe you will have to split this into slab and hardcore as two seperate elements?

I know exactly what you mean! Smile

I think the best way to sort this out is to do as WWHub says (& BTW WWH you're not incorrect in your slang interpretation!) lay you 150mm floor with it's build up as 75mm screed, 75mm insulation, 150mm concrete as one floor, apply the slab edge to this floor. You can lay another 'hardcore/gravel' layer under the floor just created using the floor tool, then model the angled section as a sweep. Use 'join geometry' to merge sweep & floor

You could try pads, but they're rubbish at angles

You may have to hide the sweep in plan views however, but you do get away without all the 'edit cut profile' manual stuff

thanks for that mathewh75. perhaps as im not having to do any takeoff/quants for the hardcore then having 2 floor buildups might be a little OTT especially if any voids/lift shafts etc move around. maybe in this case it might be that i just create a filled region on the sections - then again id have to edit the filled regions if something changed in anycase. swings and roundabouts i suppose

You can lock the floor sketch lines to the lift shaft walls, and the sweep lines & paths to the toe of the foundations allowing them to flex together, personally i think it's worth spending the time doing the little work involved in setting up the 2 floors as potentially editing all the layers in the floor for each section at the toe junctions is a right pain in the backside. Unless someone else can tell me a different way to do it?
