I am not having the best luck extracting measurements in the 3D view, as it is difficult to see what part of the cloud I am actually measuring.
The slice shown in the Overall Profile 2D viewer would be a much easier tool from which to measure.

Yes - you should currently be able to take measurements in the front and side profile views. Are you saying you can't do that with the data you have?

I think I was trying to take measurements in the Overall Profile for which the tool wasn't enabled.
I can do it within front and side profile views.
I seem to be leaving lots of lines and blocks all over my 2D view though from the profile tools, and I am not sure how to remove or move some of the elements, is there a way to understand this a little better?

Ok, I'd forgotten about the "overall" view for the polyline profile movie-mode. The idea there was for you to "play" along the route and then stop when you saw something you wanted to measure and you'd measure in the side or front views.
So I think the "lines and boxes" you are referring to are the link boxes and original polyline?
Sounds like you may simply want to use the rectangle mode. A narrow rectangle is the same as a straight polyline and effectively gives you the "overall" view in the side view panel (in which you can measure things) without all the link boxes you need for the polyline movie mode.
Just drag out a narrow rectangle in the area you're interested in and then rotate and move it to the exact location you want. Does that help?

Yep, that does explain it a bit.
I am still not quite getting how to manouever all the lines and boxes though. With the polyline profile I would like to use the pink box and move it along the line, but I don't seem able to select it, move it or delete it, I can move the line though.
I don't know how to de-select a Select by Polygon area of points.
Or how to de-select the Rectangle Profile area.
All of which makes my views quite messy and confusing.
Is there anything written to explain how to use all these tools, as I haven't managed to find it yet?

When using the Polyline PRofile you move the box by using the Play tools (in the Profile Roam group).
To remove selections of points just double-click somewhere away from the selection. That should remove the selection and any selection graphics.
To get rid of the Profile graphics you can turn the tool on and back off again - that should negate any existing graphic.
There's one eTraining video module on Point Clouds. We probably need more:
Hope that helps,

With the main 2D View active, there should be a red X in the Profile group that turns off all the profile graphics.

I see now.
It only appears when the 2D view is selected, and a LAS file is highlighted - to enable the Point Cloud tab.
This is what I was seeing before (attached).
