text/dimension on 2d isometric????
- Thread starter sonnybox
- Start date
There are lisp routines available to do this for you. I have a group of the 6 dimensions, one for each direction in each plane (with two different styles) and simply copy the one I need and stretch it. They are not associated to the objects, but most of my 2D isometrices are not to scale and I override the dimension text anyways.
the reason I do not like the LISP routines generally available for this is the use aligned dimensions instead of rotated dimensions. This forces you to be careful of where you dimension nodes are as you can quickly get a very odd looking dimension.

You are, not to put it too strongly, crazy, to be making 2D isometric drawings.
After a (okay, jagged) learning curve, you could just make models in 3D. If you like isometric style dimensions, you can put orthographic dimensions in model space, and look at the model and the dimension in an oblique view in paper space.

MikeHalloran,
3D models are all well and good, but some piping systems do not lend themselves well to properly scaled isometrics, you can have pipes that would be hidden by others. And if you doing the work in AutoCAD 3D is difficult (even with the great improvements in 2007), I would much rather do 3D work with a proper parametric solid modeling program like Inventor or ProEnginer Wildfire, etc. But the cost/benifit of this system given a enormous history of existing 2D isometrics does not usually point in favour of the use of the software.
sonnybox. If you are interested in the LISP file I have or a copy of the dimensions I use, I will put them on a free file server somewhere (any suggestions to a good one, also free).
