Dimension extension line weird behaviour

Hi all,

Take a look at the attached picture.

All dims are done with the same settings, I changed nothing inbetween dimensioning, however...

The extension lines are different. When I pull the dimension line far, far away from the object that was dimensioned the extension lines are normalise.

Does anyone have an explanation for this? And how can I fix it?

Thx for your time and knowlidge

My first guess is that "Offset from origin" (DIMEXO) is too large and "Fixed Length Extension Lines" (DIMFXLON) is ON.

Attach a sample drawing for an absolute resolution.

Here is a sample, sometimes the dim look fine, and other times...

If you 3Dorbit the drawing, and select one of the dimensions without an extension line, you'll see your dimension is at 0 elevation, but the dimension nodes are at -7983 elevation. Normally, this doesn't cause a problem, but apparently there is an issue when the extension line is a "fixed length"

To fix, I think you'll have to recreate the dimensions after either changing the UCS to the elevation of the object(s) you're dimensioning, or by changing OSNAPZ to 1 while you place the dimension(s).

(both of the suggested fixes above assume the objects in the drawing are supposed to be at different elevations)

Thx for your explanation

Much apeaciate the time and knowidge
