hey thanks all for the answers...

btw, i've been meaning to ask. what's all about the ruby or ruby console? where can i get it? sorry im quite new here though i've been using SU for quite sometime i didnt know there's more to it. haa. i'd love to learn more about it. hope you can help me! thanks!

where can i find the list of keyboard shortcuts for sketchup? thanks!

when i import dwg to sketchup, the lines are not all connected. is it really like that? i have to go trace everything again so as to make the lines functional.

and i always have that problem, i can't seem to connect all the lines properly. is there a way to solve this? thanks in advance!
