3D Stretch in Z-axis Plan view / Push-Pull
Posted: Tue Aug 15, 2017 7:32 am
I'm trying to model various complex shaped slabs with localised falls and setdowns. The aim is to continue to use the 3D model as part of the 2D documentation in the same way smart walls work. Rather than use inclined polygons and calculate the angles of each slab fall, a quicker method would be to create the overall slab (3Dslab or covered polyline maybe exploded to polygons), then -
a) in plan view, be able to identify the top surface of the 3D slab, (this could be achieved by working from the current z-h = top of slab created),
b) add a 3D snap point = add vertex to the top surface,
c) allow 3D stretch in the z-axis (up or down / push or pull) a distance input, ie -50 to stretch the surfaces down 50mm in plan view instead of having to go into various elevation views with clipcubes enabled to find the actual point you need....takes too long . Being able to add a number of snap points across a plane then push/pull each up or down whilst remaining in a plan view would be the best outcome,
d) slab setdowns are easier as punching a void then infilling with another slab or covered polyline at a lesser depth works, however, being able to add one entity to another to create a master slab would be better still. Using the Boolean add/subtract creates 3D entities with too many visible triangulated sides. The best entity to work with is the covered polyline but it is limited in the way it can be edited in elevation and once inclined off horizontal.
e) the best outcome would be to add a parametric slab builder into the smart entities
