SO i got myself this software recently. THinking of using it to draw sketches of my biulding project = a computer. Earlier ive used Google Sketchup, it was quite okay but it didnt have too good textures and also i think it was hard to draw the exakt mesurement. Anyhows, this Autodesk Inventor, or AI, for far more harder to understand? Are there any guides for using the program for tiny skectes like computers?
