survey with laser meter

Postby pace514 » Sat May 08, 2021 3:03 pm

Hi all !!!
I'm trying to survey the interior of a bathroom after its demolition in anticipation of its renovation. I'm using a DISTO 910s from Leica which provides me with a DXF documents (and jpg) as showed in the following: https://www.dropbox.com/sh/129h1uss17fu ... OPFaa?dl=0

Once imported in Sketchup, i'm having difficulties to reconstitute the puzzle. One of the problem is the fact that, obviously, nothing is perfectly flat or aligned. So, let's say you got 3 (or more) points of a wall. If you joint them, you will not get a face...unless you are incredibly lucky ! I guess you can use the 2DG and 2DW as reference but what the way to do ?

I was wondering if if someone as experience in that matter and could help me developing a workflow or giving me some tricks/advices. Any help would be greatly appreciated.

Thanks a lot

Pascal from Montréal

ps: excuse my not perfect english...

Je pense que ce laser n'est pas adapté à ce genre d'environnement complexe. Il faut ressortir le mètre ruban ;)

I think this laser is not suitable for this kind of complex environment. You have to take out the tape measure;)

I have the Disto D510 and although it's less feature rich than the S910, I would never rely on a DWG or DXF import produced by the Disto to create a SketchUp model for exactly the reason you describe.

I once tried to create a model from a DWG import provided by a survey provider and it was a nightmare. I ended up just using the DWG for reference.

I use my Disto to take the measurements and I annotate a paper sketch plan of the site with those dimensions.

If the software was more user friendly I could imagine myself transferring the Disto measurements via bluetooth to the Disto app bypassing the paper sketch plan, but even then I'm not sure...

I only do small scale residential work.

I second orbital. For CAD and modeling I want a clean approximation of the final shape of the room and as long as it's close to rectilinear that is what I'd use, while still respecting the actual dimensions in considering details or tolerances.

Good idea though to take as comprehensive photographs as possible of existing framing and plumbing to remain. And measure these accurately. Model or draw in CAD if it helps. I usually don't have time (or opportunity) to record specific existing wall framing, but it can be helpful, especially in an older building.

Here's my best guess.
