Just curious if there is a way that I can perform an offset, then pick the beginning point then the end point and it will offset every 9 feet or so. I know this is probly a no brainer, ... just cant think of the command to do this. thxs
-
Are you aware of the "Through" option in offset or maybe the array command? It's hard to tell exactly what you're aiming for. from your description. Maybe a sketch will help you explain.
-
Ok. I was not aware. Thanks for pointing that out, but still not getting it to do what I want...
-
Then please refer to the rest of my response.
-
Array should be perfect for that...? Or maybe we do need a sketch? :-)
-
Best example I can come up with is the following:
Parking Stalls,
being able to select an object. tell it I want it to offset 9 feet from the point of begging to the end. It will offset in between.
I need to look at the measure tool and array...

There are parking stalls as dynamic blocks that will do what you are after on the tool palette

Yes, there's an app for that! :-P
If you need the end to be the same distance as the beginning, using array is where you want to go.
If you don't care what the end result is, simply copy; 9', 18', 27', ...
If you need specific measurements between the beginning and end, draw a line from beginning to end, set your Point Style to something other than a point or blank (so you can see/access the nodes), divide the line by the amount of spaces you need (not the count of lines between the spaces, but the spaces themselves), draw your line/object & copy from node to node (not so quick & dirty but it works easily enough).

I use this to offset most anything but trusses in plan view is what I use it for the most.
It now uses one of Lee's older Vector Offset routines. See the two functions at the very end to call the routine from the command line.
;; ArrayObjects is a modified from of Lee Mac Array on Vector
;; This engine allowed me to replace several of my stand
;; alone lisp routines, now I have a versatile offset routine.
