hi all, i am an architect and a newbie too mathematica. i wish to build a program related to parametric geometrical design (2 dimensional floor plans) and parametric geometrical optimization. a few questions pops up and will just write them randomly as i think of one. 1. is there a way to draw vectors in mathematica the way we draw in autocad--meaning by more intuitive freehand mouse and visually drawing it instead of inputting formulas and nos. and rules? say, i want a quick drawing of a house, it's more intuitive to draw vector lines using mouse. 2. how do i export vector drawings into mathematica from Autocad( dwg or dxf) ? 3. how do i measure areas and lengths of segments or radius of curves of the elements of the imported vector drawings? 4. If i don't import the file/drawing, can mathematica "read" Autocad drawings? 5. as mentioned, I'm a newbie to mathematica and thought i should embark on this project by improving my proficiency in analytical geometry first as a starting point. I wish to use mathematica to learn and self-study about analytical geometry, is this possible and if so, can mathematica "Teach" me? any other suggestions as on how best to approach my 'project goals' are welcome and thanks in advance for your assistance! Jim
