Hans,

Thank you for your attention.  How does one apply a patch to Dia?

I just spent a few hours modeling a test rack in Solidworks.  The roller

be a good system.

Now I would like to know which version of Dia you are referring to.
The behaviour of Dia 0.97.1 and before was considered improveable,
so it got changed by https://bugzilla.gnome.org/show_bug.cgi?id=540210

But significantly the zoom level changes a lot less per
step making it very useful.

The scaling per step also got smaller by the patch above.

I never gave this much thought, but I will set
the cursor off center towards what I want to be centered and I will roll it
back and forth this has the effect of scooting the view towards the center I
am after.

So you can probably easily adapt to the improved behaviour, too ;-)

So then I wonder I can adjust the amount of zoom myself?

Not without compiling Dia yourself. But if you intend to to it look at:
http://git.gnome.org/browse/dia/commit/?id=dc4fccba65a30dec1c81b4506a0f44fb880ceaa4
(Also linked in the bug report mentioned above.)

I don't use the
roller button to zoom in Dia as much as I would, and I can't take issue with
Andrey's comment that the diagram quickly is lost if you are not very
careful.

Knowing ctrl+E certainly helps. Of course there also it the menu entry View/Best Fit.
