So taking a breather from Pojects I was thinking about the post I did regarding the mirror command (using mirror and rotate at the same time). The more I think about it I wonder which is faster - the mirror copy/rotate or a simple polar array. Granted, the array will create 4 lines instead of 2- but they would be the correct size and orientation. I think bits like this is what makes AutoCAD so interesting yet challanging - there are lots of ways to do things, and each person may accomplish the same thing in different ways. So once you get to a certain skill level, and are accustomed to a certain way that they are comfortable, it is hard to pick up new ideas since the tricks are often in the subtle details of easy commands.
One of these days I am going to challange myself to see how many commands I use on a simple drafting package. I think there would be more dimensioning / text / and layout commands used than most of teh rest of the drafting.
