Sorry, I probably did not explain well what I mean. Sometimes it really make sense for ISO drawings to create a small gap between the piece and the extension line. My question meant: Is there a case for a single dimension, when the gap should be made between the piece and e.g. the extension line from the dimension starting point, but not between the piece and the extension line from the dimension ending point? This would mean to split the setting into actually 2 independent values (let's say "Start Gap" and "End Gap").
I would certainly like that kind of degree of freedom, but I'm not sure if it's worth the effort. For me, as a user, the main convenience would be a possibility to switch between a gap and no gap for the whole dimension. If I've understood correctly, the main points said in this discussion are:
- The default for a dimension should be as close to the standard as possible when the dimension is created, whatever the current standard is
- When the standard for a dimension is changed to some other standard by the user, all the related dimension options for that dimension should be reset accordingly, to the values of the standard defaults.
- User may be able to change certain aspects of the dimension after it's created with its default standard-obeying values
Also, currently, a user can freely select different standards for different dimensions in a single drawing. This does not make any sense, but at least I like the freedom of possibility to do stupid things!
Another "issue" which comes to mind is, if you are dimensioning for example a circle. If the circle is big enough, the 6x line width ASME gap between the opposite points on the circle and the extension line ends is not sufficient to create a visible break. In such a case it would make sense to actually provide the "Gap Size" in distance units, instead of fixed line width multiple. Did anyone encounter this imperfection as a real problem?
I have noticed this issue before, but at least for me it hasn't been a problem. I mostly use the inner diameter dimension placement for big circles, anyway. Maybe it might be a problem for someone else, it's difficult to say.
