Here's a nice example of something that was easy to model in Rhino (about 1hr). It matches the point cloud to within +/-5mm. Sure, you could do it in Revit, but it's much harder.

The final output depends upon its future use or purpose.

Certainly Revit could achieve this, however, like you say, you should pick the tools which suit you.

Nice model :)

Thanks, I would think so too, and when you say quality of point cloud data, is 3cm tolerance a good quality? Sorry for the dummy question, very new to this area.

3cm is rather sparse.

3cm is rather sparse.
On a wall a meter long 3cm is sparse. On a wall 100m long it's not. It's all a question of scale and scope. What have you been asked to do, what did you promise to do, and what is really necessary?

If you have to produce something in Revit then you should agree a tolerance before you start. Let's say you are drawing a wall at 1:100 scale on a 2D plan - +/-30mm is fine, becuase you cannot measure to any greater accuracy on a 1:100 drawing with a scale rule. It's all 3D and digitial now, so a model in Revit can be shown in whatever scale is chosen. You could model to +/-30mm and your client could try to plot a drawing from the model at 1:10 scale - this drawing would not be accurate.

Agree your scope with your client before you start and stick to it. Otherwise you will have to do whatever they ask, which will be difficult.
If you don't see that there is nothing, then you are kidding yourself.

Thanks for all the good suggestions, I will pass on to the boss, he is dealing with client and we are both new in this area, so do not have a specification agreed before starting the work, still in the "learning by doing" process. :D
