so true..architects need this.--grasshopper logic to sketch-up
here's an idea ...how about break it down n develop a simple plugin that can have implied relation between entities .for eq i use the loft or skin plugin to create organic shape using 3 benzier curves. now the plugin should make sure relation between curves n the function ( tht is to loft) is intact or preserved ...so tht @ later stage if designer feels to change the curve profile (let say using control point) the organic shape modifies simultaneously...the idea is that several iterations can be developed from one concept n its intuitive ...

WHAT I MEAN IS ,THIS PLUGIN SHOULD BREAK THE SEQUENTIAL MAKE MODELLING IN SU .THAT IS, IT SHOLUD NOT BE LIKE--- GEOMETRY(eg rec)>>> THAN ACTION (push)>>> THAN RESULT (box)>>> BUT THE ALGORITHMIC RELATIONSHIP SHOULD BE MADE POSSIBLE _____ THAT'S WHAT GRASSHOPPER DOES TO RHINO ...N WE NEED SOMETHING LIKE THT FOR SKECTCHUP

AM I MAKING SENSE, GUYS? PLZ RESPOND
