Hello, I am trying to populate a TIN 3D surface with components. Within each triangle surface I would like two random components( represented by different colored dots in attached picture). Does anyone have any idea of how to populate the TIN more quickly than placing every component by hand. The TIN was imported into sketchup from ArcGIS.
I produced this resultsDots on Face.jpg
with this code
def placethedots mod = Sketchup.active_model ent = mod.active_entities sel = mod.selection cdefs = mod.definitions.reject{|cd| cd.group?||cd.image?} faces = sel.grep(Sketchup;;Face) faces.each{|f| tx=0.0;ty=0.0;tz=0.0; p=f.outer_loop.vertices.collect{|v|v.position} p.each{|v| tx+=v.x;ty+=v.y;tz+=v.z} ax=tx/p.length;ay=ty/p.length;az=tz/p.length ctr=Geom;;Point3d.new(ax,ay,az);#ent.add_cpoint(c) pt1=ctr.offset([-6,6,0]) cd=cdefs[rand(cdefs.length)] ent.add_instance(cd,Geom;;Transformation.new(pt1,f.normal)) pt2=ctr.offset([6,-6,0]) cd=cdefs[rand(cdefs.length)] ent.add_instance(cd,Geom;;Transformation.new(pt2,f.normal)) } endI first created the six component "dots". Selected the faces then executed the code.
