Lines and Dimensions

I've been using Autocad for years to do light personal projects and I feel

very comfortable but I've skipped over learning the basics and I tend to just make do with what I know. I'd like to learn the right and quickest way for a

couple of areas like setting line start, end and length and setting exact dimensions.

Currently I just select the line tool, clink my start point by eye move the mouse

while watching the length in the lower left and then click the end point. If I'm using something like .0000 precision it seems my lines end up being 1.0015, etc. I'd like to be able to tell it the exact length. I've used the "lengthen" command and that works but seems like a lot of work, is there not a quick edit somehow?

I'd also like to specify the exact start or end in my current scale, like start at 2" x 2", is that possible?

I also have the same issue with dimensions they end up being 2.0123 instead of 2.125.

This is Autocad Arch 2. Thanks!

Start your line command, click a point, drag the mouse in the direction you want the line to be drawn in, type in the exact length that you want that line to be and hit enter.

Exact line lengths can be obtained using direct distance entry. Ex. - you want a line to be 2.375" long. Start the line command, pick your starting point (make sure Orthomode is enabled) then at the command line type @2.375>0 or whatever the angle is or just drag your cursor in the direction you want to go. This is but one option; there are others.

Yes, you can do that to any precision you want. Start your line command, drag the mouse in the direction you want it to go and do a keyboard entry of the exact distance. You can have it be 2.125 if you want, or 2.12586924 or what ever, out to 8 digits. If you want to start at an exact point, simply start the line or circle or whatever, and when it says "specify first point" on the command line you can enter the cooridinates you want. if you enter 2,2, that will give you a starting point at 2 over and 2 up from the zero point of the current ucs. If you enter 2,2,2 you'll get the same point in x and y, but elevated in the z axis by 2 units.

Help files on coordinate entry will tell you all about it.

I suggest you go through the tutorials either on your Autocad disc or on this site. There are an assortment of books on the vertical products. For one that old, you may have to dig a bit, but they are still out there.

Remark types faster than I do too...

Too cool... and too simple, thanks guys!

In addition to direct distance entry, become familiar with offset, trim and extend commands. (o, tr, tr+shift)

And of course object snaps shift+right mouse button.
