Ah, this is useful. Let me mess around with this.
Somebody has been busy since I last checked two years ago.

Hi,
It is very likely that better CAD functionality will hit QGIS soon. An
approach based on the CadInput plugin [1] is being discussed [2] and
parted to core [3]. Maybe this does already provide a lot of what you need?
Best regards,
Matthias

The line thickness is good. The endpoints could be improved.
Crossmarks would be better than dots. If dot endpoints are easiest to
program, then put a smaller white dot in the middle of the larger red
dot. This will help measurement accuracy. The most desirable quality
of the tool would be for the markers remain on screen until cleared by
the user. This includes remaining on screen while other commands are
selected and new data entered. This onscreen persistence should also
be applied to the angle measure tool.
With robust CAD tools this would not be an issue because the operator
can quickly draw temporary measure lines on screen and erase them at
his leisure. With QGIS the CAD tool functionality is clumsy and
inefficient. Data point creation with other systems is fast and well
developed. Most CAD systems allow inputting a data point, then drawing
the next point using a relative angle and distance at the keyboard or
visually with onscreen angle and distance display controlled by snap
settings. Perhaps what I'm really asking for is better CAD tool
functionality.
I have many *thousands* of points to calculate and enter by hand.
Months worth of work. If I were a programmer perhaps this would not be
necessary. Unfortunately I don't think I have the time to spend a
month or two getting up to speed programming in the QGIS environment,
not that I would not like to. I just spent 7 months learning a foreign
language to translate documents for my project. When the functionality
of the measure tool changed after QGIS 2.1(1.8, 2.1 something like
that), and the measure tool lost its persistence I despaired.
I am pressing for this functionality because I need to finish my
project and put food on the table.
Anyway, this is my project, analyzing ships navigation data:

In this project QGIS is merely a tool to develop a better
understanding of historical events. What will really be significant is
when QGIS goes 3D and I am able to visualize aircraft and ships data
simultaneously in an animation using the animation plug-in.

The measure tool onscreen markers are not persistent and are
therefore not useful. Why have tools that have no useful
function? I've complained about this before, filed a ticket and
was argued down by a developer.
It is frustrating to try to contribute to a project when nobody
wants to cooperate.
I don't think it is fair to characterise QGIS as a project where
nobody wants to cooperate. People are busy, may have differing
opinions to you, may not have noticed your ticket etc. We are a
community of people trying our best to cooperate and sometimes we
fail, but it certainly isn't through a lack of desire to cooperate.
My advice is keep trying (in a friendly way) to get your request
noticed, and if others don't always agree with your ideas, don't take
it personally.

Tim
