Dimensioning Isometric Drawings

Back in school, I learned how to dimension Isometric drawings (at least I
think I did) so that they matched the planes. Does anyone remember how? I'm
using A2k.

Imangine an iso cube:

Left face -- rotate=-30, oblique=-30,
Right face -- rotate=30, oblique=30

top
right oriented -- rotate=30, oblique=-30
left oriented -- rotate=-30, oblique=30

I don't know of any way to use the traditional dimension comands to get tick
marks and such. I just draw the dimension lines manually.

Usually you put an aligned dimension, and then oblique it to 30, 90 or
150 degrees. Keep the text setting horizontal. If you want the dimension
text to appear to be in the plane of the dimension, add an oblique angle
of either +30 or -30 degrees to the text, and set it to align with the
dimension line. Making left and right obliqued styles will help with this
approach.

The add-on below will oblique dimensions automatically to the angle
you pick from a menu. A trial version is at:

Albert,
In the Dim Style Dialog box under text, look at alignment, there is ISO standard you can check. I haven't tried this, but you might want to create a style with that text alignment set and then make sure your faces are set right, iso top, left, right, when you dimension each side. I'm not going to guarantee this will work, we don't do ISO's here, but I did do it in school and at a previous job, so, I know it can be done and this may be the variable in 2000 that you're looking for. - Deb

Albert,
Have you considered drawing in 3d wireframe instead of a flat iso. If you
change your view to SEISO (or any other isometric viewpoint), you can draw
your parts to scale in height, width, and depth, then orient your UCS
accordingly and dimension as usual. If you want the drawing to appear solid,
trim using VIEW option. I can't imagine trying to draw an accurate isometric
drawing on a flat plane, and having the dimensions associative and accurate,
especially since it is so easy to draw in 3 dimensions.

Debjoh,

That ISO Standard in the Text tab of the Ddim dialog box refers to the
text's alignment, as follows:

"Aligns text with the dimension line when text is inside the extension
lines, but aligns it horizontally when text is outside the extension
lines."

It actually does not have anything to do with aligning dimensions
accordingly to the current isometric plane.

Some solutions to this can be found looking for "isometric dimensioning"

Refer to http://www.uti.com/~boudreau/jjc102/isometrx.html for illustrations
(drawings) containing the proper oblique and trotate settings needed for
creating Isometric drawings in AutoCAD. There's also a drawing show the
dimblk1 and dimblk2 arrowheads that should be created for the proper
cosmetics shown in the resulting dimensions.
